Iran
–
Iran, also known as Persia, officially the Islamic Republic of Iran, is a sovereign state in Western Asia. Comprising a land area of 1,648,195 km2, it is the second-largest country in the Middle East, with 82.8 million inhabitants, Iran is the worlds 17th-most-populous country. It is the country with both a Caspian Sea and an Indian Ocean coastline. The countrys central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, Tehran is the countrys capital and largest city, as well as its leading economic and cultural center. Iran is the site of to one of the worlds oldest civilizations, the area was first unified by the Iranian Medes in 625 BC, who became the dominant cultural and political power in the region. The empire collapsed in 330 BC following the conquests of Alexander the Great, under the Sassanid Dynasty, Iran again became one of the leading powers in the world for the next four centuries. Beginning in 633 AD, Arabs conquered Iran and largely displaced the indigenous faiths of Manichaeism and Zoroastrianism by Islam, Iran became a major contributor to the Islamic Golden Age that followed, producing many influential scientists, scholars, artists, and thinkers. During the 18th century, Iran reached its greatest territorial extent since the Sassanid Empire, through the late 18th and 19th centuries, a series of conflicts with Russia led to significant territorial losses and the erosion of sovereignty. Popular unrest culminated in the Persian Constitutional Revolution of 1906, which established a monarchy and the countrys first legislative body. Following a coup instigated by the U. K. Growing dissent against foreign influence and political repression led to the 1979 Revolution, Irans rich cultural legacy is reflected in part by its 21 UNESCO World Heritage Sites, the third-largest number in Asia and 11th-largest in the world. Iran is a member of the UN, ECO, NAM, OIC. Its political system is based on the 1979 Constitution which combines elements of a democracy with a theocracy governed by Islamic jurists under the concept of a Supreme Leadership. A multicultural country comprising numerous ethnic and linguistic groups, most inhabitants are Shia Muslims, the largest ethnic groups in Iran are the Persians, Azeris, Kurds and Lurs. Historically, Iran has been referred to as Persia by the West, due mainly to the writings of Greek historians who called Iran Persis, meaning land of the Persians. As the most extensive interactions the Ancient Greeks had with any outsider was with the Persians, however, Persis was originally referred to a region settled by Persians in the west shore of Lake Urmia, in the 9th century BC. The settlement was then shifted to the end of the Zagros Mountains. In 1935, Reza Shah requested the international community to refer to the country by its native name, opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably

Tupolev Tu-154
–
The Tupolev Tu-154 is a three-engine medium-range narrow-body airliner designed in the mid-1960s and manufactured by Tupolev. It was exported to 17 non-Russian airlines and used as a transport by the air forces of several countries. With a cruising speed of 900 kilometres per hour the Tu-154 is one of the fastest civilian aircraft in use and has a range of 5,280 kilometres. Since 1968 there have been 39 fatal incidents involving the Tu-154, most of which were caused either by factors unrelated to the aircraft, following a crash in 2016 all Tupolev Tu-154 aircraft in Russia were grounded. However, the Tu-154 is still being used as of January 2017, the Tu-154 was developed to meet Aeroflots requirement to replace the jet-powered Tu-104, the Antonov An-10 and the Ilyushin Il-18 turboprops. A takeoff distance of 2,600 metres at maximum weight was also stipulated as a requirement. The Soviet Ministry of Aircraft Industry chose the Tu-154 as it incorporated the latest in Soviet aircraft design, the first project chief was Sergey Yeger, in 1964, Dmitryi S. Markov assumed that position. In 1975, the lead role was turned over to Aleksandr S. Shengardt. The Tu-154 first flew on 4 October 1968, the first deliveries to Aeroflot were in 1970 with freight services beginning in May 1971 and passenger services in February 1972. There was still limited production of the 154M model as of January 2009 despite previous announcements of the end of production in 2006,1025 Tu-154s have been built,214 of which were still in service as of 14 December 2009. The last serial Tu-154 was delivered to the Russian Defense Ministry on 19 February 2013 from the Aviakor factory, equipped with upgraded avionics, a VIP interior, the factory has four unfinished hulls in its inventory which can be completed if new orders are received. The Tu-154 is powered by three rear-mounted low-bypass turbofan engines arranged similarly to those of the Boeing 727, but it is larger than its American counterpart. Both the 727 and the Tu-154 use an S-duct for the middle engine, the original model was equipped with Kuznetsov NK-8-2 engines, which were replaced with Soloviev D-30KU-154 in the Tu-154M. All Tu-154 aircraft models have a relatively high thrust-to-weight-ratio which give excellent performance and this became an important factor in later decades as fuel costs grew. The flight deck is fitted with conventional dual yoke control columns, Flight control surfaces are hydraulically operated. The cabin of the Tu-154, although of the same six-abreast seating layout, gives the impression of an interior, with a lower ceiling than is common on Boeing. The passenger cabin accommodates 128 passengers in a layout and 164 passengers in single-class layout. The layout can be modified to what is called a winter version where some seats are taken out, the passenger doors are smaller than on its Boeing and Airbus counterparts

Iran Air Tours
–
Iran Air Tours is an airline based in Tehran, Iran. The airline mainly operates under the English name Iran Airtour as written in Persian and this error is due to confusion between different pluralization rules in English and Persian. The airline was established in 1973 by Iran Air and started scheduled operations in the early 1990s with services for its domestic tours division, for a brief period, the Yakovlev Yak-42D was also operated. The airline was the customer for Iranian-assembled version of the Ukrainian-designed Antonov 140 turboprop. Due to unpublicized reasons, the carrier did not accept deliveries of the type, Iran Air Tours was also to have received several Tupolev Tu-204SM aircraft. As of April 2014, these aircraft had not been delivered due to the United States economic embargo against Iran, with the February,2011 grounding of all Tupolev Tu-154 aircraft in Iran, Iran Air Tours was faced with loss of its primary type. A number of used McDonnell Douglas MD-80 series aircraft were brought online, for a brief period in 2006-2007, two Airbus 300 aircraft were operated but these were transferred to the parent Iran Air. Two Airbus A320-200s were also operated for a few months in 2012, two Boeing 737 Classics were added to the fleet in 2016. The collision killed 133 people – both pilots of the Su-24 and all 12 crew members and 119 passengers on board the Tu-154. 12 February 2002 Flight 956, a Tupolev Tu-154M, crashed into the Sefid Kooh mountains during heavy rain, snow, all 12 crew members and 107 passengers were killed.

Aircraft registration
–
In accordance with the Convention on International Civil Aviation, all civil aircraft must be registered with a national aviation authority using procedures set by each country. Every country, even those not party to the Chicago Convention, has a NAA whose functions include the registration of civil aircraft, an aircraft can only be registered once, in the one jurisdiction. The registration identifier must be displayed prominently on the aircraft, most countries also require the registration identifier to be imprinted on a permanent fireproof plate mounted on the fuselage in case of a post-fire/post-crash aircraft accident investigation. Military aircraft typically use tail codes and serial numbers, although each aircraft registration identifier is unique, some countries allow it to be re-used when the aircraft has been sold, destroyed or retired. For example, N3794N is assigned to a Mooney M20F and it had been previously assigned to a Beechcraft Bonanza. Also note that an aircraft may be assigned different registrations during its existence. This can be because the aircraft ownership, jurisdiction of registration. The first use of aircraft registrations was based on the radio callsigns allocated at the London International Radiotelegraphic Conference in 1913, the format was a single letter prefix followed by four other letters. The major nations operating aircraft were allocated a letter prefix. Smaller countries had to share a single letter prefix, but were allocated exclusive use of the first letter of the suffix and this was modified by agreement by the International Bureau at Berne and published on April 23,1913. The agreement stipulated that the nationality marks were to be followed by a then a group of four letters that must include a vowel. This system operated until the adoption of the system in 1928. The International Radiotelegraph Convention at Washington in 1927 revised the list of markings and these were adopted from 1928 and are the basis of the currently used registrations. The markings have been amended and added to over the years, upon registration, the aircraft receives its unique registration, which must be displayed prominently on the aircraft. Annex 7 to the Chicago Convention describes the definitions, location, the aircraft registration is made up of a prefix selected from the countrys callsign prefix allocated by the International Telecommunication Union and the registration suffix. Depending on the country of registration, this suffix is a numeric or alphanumeric code, a supplement to Annex 7 provides an updated list of approved nationality and common marks used by various countries. When painted on the fuselage, the prefix and suffix are usually separated by a dash, when entered in a flight plan, the dash is omitted. In some countries use a number suffix rather than letters, like the United States, South Korea, and Japan

Islamic Republic of Iran Air Force
–
The Islamic Republic of Iran Air Force is the aviation branch of the Islamic Republic of Iran Army. The present Air Force came into being in the early 1980s when the former Imperial Iranian Air Force was renamed, the Air Force has attempted with some success to maintain in service the large number of American-built aircraft which Iran acquired during the Shahs regime. The Air Force has turned to purchases of Soviet and Chinese aircraft, as well as pressing ex-Iraqi aircraft into service, and indigenously built aircraft, in order to maintain a capable force. As of June 2016, the Islamic Republic of Iran Air Force possesses 348 fighters, making it the ninth most powerful air arm in the world, on paper. The IRIAF came into being when the former Imperial Iranian Air Force was renamed following the Islamic Revolution in Iran, due to strained relations with the west, Iran had to procure new equipment from Brazil, Russia and the Peoples Republic of China. Since the Revolution, the composition of the IRIAF is hard to determine. Many aircraft belonging to the Iraqi Air Force took refuge in Iran during the Persian Gulf War in 1991, and many were put into service with the IRIAF or taken apart for spare parts. Due to the spare parts shortages faced by the air force. In 2002, Iran with the co-operation of Ukraine, successfully started the manufacture of the Iran-140, simultaneously, Iran began construction of two domestically produced fighters, upgraded using technology from the F-14 Tomcat and the F-5 Tiger II. The fighters have been named the Azarakhsh and the Shafaq, since then the country has also become self-sufficient in the manufacture of helicopters. The country claims that it is capable of producing the old U. S. AH-1 Cobra gunship, additionally, Iran also produces Bell Helicopter Bell 212 and Bell 206 helicopters in serial production. These are known respectively as the Shabaviz 2-75 and the Shabaviz 206, a series of purges and forced retirements resulted in the manpower of the service being halved between February 1979 and July 1980, leaving the IRIAF ill-prepared for the Iran–Iraq War. The Iranians retaliated with operation Kaman-99 which involved 206 F-4, F-5, on 23 September 1980, Iran launched Operation Kaman 99 as 40 F-4 Phantoms, armed with Mark 82, Mark 83 and Mark 84 bombs and AGM-65 Maverick missiles, took off from Hamadan. After refueling in mid-air the Phantoms reached the Iraqi capital Baghdad, meanwhile, eight More F-4s took off from Tehran and launched a second attack on the al-Rashid airbase. Iran proceeded to launch 58 F-5E Tiger IIs from Tabriz, which were sent to attack Mosul Airbase, after the attack on Mosul Airbase, another 50 F-5Es were dispatched to strike Nasiriyah Airbase, which was heavily damaged. As all 146 Iranian F-4s and F-5s had been sent for a raid on Iraq,60 F-14 Tomcats were scrambled to defend Iranian airspace against a possible Iraqi retaliation. Iranian F-14s managed to down 2 Iraqi MiG-21s and 3 Iraqi MiG-23s, Iraqi MiG-23s managed to down 2 F-5Es, while Iraqi MiG-21s also downed 2 F-5Es. Iraqis also by mistake shot down one of their own Il-76MD strategic airlifters with a SA-3 SAM, saddam Hussein and the Iraqi military were dealt a heavy blow when Iranian Air Force vulnerabilities failed to materialize

Sukhoi Su-24
–
The Sukhoi Su-24 is a supersonic, all-weather attack aircraft developed in the Soviet Union. The aircraft has a wing, twin-engines and a side-by-side seating arrangement for its two crew. It was the first of the USSRs aircraft to carry an integrated digital navigation/attack system and it remains in service with the Russian Air Force, Ukrainian Air Force, and various air forces to which it was exported. One of the conditions for accepting the Sukhoi Su-7B into service in 1961 was the requirement for Sukhoi to develop a variant capable of precision air strikes. Preliminary investigations with S-28 and S-32 aircraft revealed that the basic Su-7 design was too small to contain all the avionics required for the mission, oKB-794 was tasked with developing an advanced nav/attack system, codenamed Puma, which would be at the core of the new aircraft. That same year, the United States proposal for their new all-weather strike fighter would be the TFX, the resulting F-111 would introduce a variable-geometry wing for greatly increased payload, range, and low-level penetration capabilities. In 1962–1963, Sukhoi initially set out to build an aircraft without the complexity of moving wings like the F-111 and it designed and built a mockup of S-6, a delta wing aircraft powered by two Tumansky R-21F-300 turbojet engines and with a crew of two in a tandem arrangement. The mockup was inspected but no work was ordered due to lack of progress on the Puma hardware. In 1964, Sukhoi started work on S-58M, the aircraft was supposed to represent a modification of the Sukhoi Su-15 interceptor. In the meantime, revised Soviet Air Force requirements called for a strike aircraft with STOL capability. A key feature was the ability to cruise at speeds at low altitude for extended periods of time in order to traverse enemy air defenses. To achieve this, the included two Tumansky R-27F-300 afterburning turbojets for cruise and four Kolesov RD-36-35 turbojets for STOL performance. Side-by-side seating for the crew was implemented since the large Orion radar antennas required a large frontal cross-section, to test the six-engine scheme, the first Su-15 prototype was converted into S-58VD flying laboratory which operated in 1966–1969. The aircraft was officially sanctioned on 24 August 1965 under the internal codename T-6, the first prototype, T-6-1, was completed in May 1967 and flew on 2 July with Vladimir Ilyushin at the controls. The initial flights were performed without the four lift jets, which were installed in October 1967, at the same time, R-27s were replaced with Lyulka AL-21Fs. So the six-engine approach was abandoned, by 1967, the F-111 had entered service and demonstrated the practical advantages and solutions to the technical problems of a swing-wing design. On 7 August 1968, the OKB was officially tasked with investigating a variable geometry wing for the T-6, the resulting T-6-2I first flew on 17 January 1970 with Ilyushin at the controls. The subsequent government trials lasted until 1974, dictated by the complexity of the on-board systems, the crew was equipped with Zvezda K-36D ejection seats, allowing the crew members to bail out at any altitude and flight speed, including during takeoff and landing

Tehran
–
Tehran is the capital of Iran and Tehran Province. It is ranked 29th in the world by the population of its metropolitan area, in the Classical era, part of the present-day city of Tehran was occupied by a Median city that in the Avesta occurs as Rhaga. It was destroyed by the Mongols in the early 13th century, the capital has been moved several times throughout the history, and Tehran is the 32nd national capital of Iran. The city was the seat of the Qajars and Pahlavis, the two last imperial dynasties of Iran. It is home to historical collections, such as the royal complexes of Golestan, Sadabad. Large scale demolition and rebuilding began in the 1920s, and Tehran has been a destination for the migrations from all over Iran since the 20th century. Tabiat Bridge, which was completed in 2014, is considered the third symbol of the city. There have been plans to relocate Irans capital from Tehran to another area, due mainly to air pollution, to date, no definitive plans have been approved. A2016 survey of 230 cities by consultant Mercer ranked Tehran 203rd for quality of living, according to the Global Destinations Cities Index in 2016, Tehran is among the top ten fastest growing destinations. The origin of the name Tehran is uncertain, the settlement of Tehran dates back over 7,000 years. The present-day city of Tehran was a suburb of an important Median city that was known as Rhaga in Old Persian, in the Avestas Videvdat, Rhaga is mentioned as the twelfth sacred place created by the Ohrmazd. In Old Persian inscriptions, Rhaga appears as a province and it was a major area for the Iranian tribes of Medes and Achaemenids. From Rhaga, Darius the Great sent reinforcements to his father Hystaspes, in some Middle Persian texts, Rhaga is given as the birthplace of Zoroaster, although modern historians generally place the birth of Zoroaster in Khorasan. Derived into Modern Persian as Rey, it now as a city located towards the southern end of the modern-day city of Tehran. Mount Damavand, the highest peak of Iran, which is located near Tehran, is an important location in Ferdowsis Shahname, the long Iranian epic poem that is based on the ancient epics of Iran. It appears in the epics as the birthplace of Manuchehr, the residence of Keyumars, the place where Freydun binds the dragon fiend Aži Dahāka, during the Sassanid era, in 641, Yazdgerd III issued his last appeal to the nation from Rey, before fleeing to Khorasan. Rey was dominated by the Parthian Mihran family, and Siyavakhsh—the son of Mihran the son of Bahram Chobin—who resisted the Muslim Invasion, because of this resistance, when the Arabs captured Rey, they ordered the town to be destroyed and ordered Farrukhzad to rebuild the town anew. In the 9th century, Tehran was a well known village, but less known than the city of Rey, the medieval writer Najm od Din Razi declared the population of Rey about 500,000 before the Mongol Invasion

Mashhad
–
Mashhad is the second most populous city in Iran and capital of Razavi Khorasan Province. It is located in the northeast of the country, close to the borders of Turkmenistan and Afghanistan and its population was 2,749,374 at the 2011 census and its built-up area was home to 2,782,976 inhabitants including Mashhad Taman and Torqabeh cities. It was a major oasis along the ancient Silk Road connecting with Merv in the East, the city is most famous and revered for housing the tomb of Imam Reza, the eighth Shia Imam. Every year, millions of pilgrims visit the Imam Reza shrine, the Abbasid caliph Harun al-Rashid is also buried within the shrine. Mashhad has experienced the rise and fall of many governments over the course of history, many Arab, Turkish, and especially Mongolian and Afghan tribes have brought great changes in the language, ethnicity and culture of the people each in their own time. Surprisingly, Mashhad enjoyed relative prosperity in its economy in the Mongol period, Mashhad is mistakenly known as the city of Ferdowsi, the Iranian poet of Shahnameh, which is considered to be the national epic of Iran. Ferdowsi and Akhavan Sales are both buried in Tus, an ancient city that is considered to be the origin of the current city of Mashhad. On 30 October 2009, Irans then-President Mahmoud Ahmadinejad declared Mashhad as Irans spiritual capital, the name Mashhad comes from Arabic, meaning the place of martyrdom the place where Ali ar-Ridha, the eighth Imam of Shia Muslims, suddenly died and so his shrine was placed there. At the beginning of the 9th century, Mashhad was a village called Sanabad. There was a palace of Humayd ibn Qahtaba, the governor of Khurasan. In 808, when Harun al-Rashid, Abbasid caliph, was passing through there to quell the insurrection of Rafi ibn al-Layth in Transoxania, he became ill and he was buried under the palace of Humayd ibn Qahtaba. Due to this event, the Dar al-Imarah was known as the Mausoleum of Haruniyyeh. Several years later in 818 Ali al-Ridha was martyred by al-Mamun and was buried beside the grave of Harun. Although some believe that after this event, the city was called Mashhad al-Ridha, it seems that Mashhad, as a place-name, first appears in al-Maqdisi, about the middle of the 14th century, the traveller Ibn Battuta uses the expression town of Mashhad al-Rida. Shias started visiting there for pilgrimage of his grave, by the end of the 9th century, a dome was built on the grave and many buildings and bazaars sprang up around it. During more than a millennium it has been devastated and reconstructed several times, in 1161 however, the Ghuzz Turks succeeded in taking the place, but they spared the sacred area in their pillaging. Thus the survivors of the migrated to Mashhad. The only well-known food in Mashhad, sholeh Mashhadi or Sholeh, dates back to the era of the Mongolian invasion when it is thought to be cooked with any food available and be a Mongolian word

Aviation accidents and incidents
–
If the aircraft is destroyed or severely damaged so that it must be written off, it is further defined as a hull loss accident. Annex 13 further defines an aviation incident as an occurrence, other than an accident,583, The Tenerife airport disaster, which occurred on March 27,1977, remains the accident with the highest number of airliner passenger fatalities. 583 people died when a KLM Boeing 747 attempted to take off without clearance, there were no survivors from the KLM aircraft,61 of the 396 passengers and crew on the Pan Am aircraft survived. Pilot error was the cause, as the KLM captain began his takeoff run without obtaining air traffic control clearance. A contributing factor was the dense fog, the KLM flight crew could not see the Pan Am aircraft on the runway until immediately before the collision. The accident had a influence on the industry, particularly in the area of communication. An increased emphasis was placed on using standardized phraseology in air traffic control communication by controllers and pilots alike. Furthermore, all members of the crew are now able to question the captains judgment concerning the safety of the airliner. 520, The crash of Japan Airlines Flight 123 on August 12,1985, is the disaster with the highest number of fatalities,520 people died on board a Boeing 747. Pilots were able to keep the plane flying for 32 minutes after the mechanical failure before crashing into a mountain, all 15 crew members and 505 of the 509 passengers on board died. The death toll was exacerbated by delays in the rescue operation, although a number of people survived the impact, by the time the Japanese rescue teams arrived at the crash site all but four had succumbed to their injuries. 349, On November 12,1996, the worlds deadliest mid-air collision was the Charkhi Dadri mid-air collision involving Saudia Flight 763 and Kazakhstan Airlines Flight 1907 over Charkhi Dadri, the collision was mainly the result of the Kazakh pilot flying lower than the assigned clearance altitude. All 349 passengers and crew on both aircraft died. The Ramesh Chandra Lahoti Commission, empowered to study the causes, recommended the creation of the semi-circular rule,346, On March 3,1974, Turkish Airlines Flight 981, a McDonnell Douglas DC-10, crashed in a forest northeast of Paris, France. The London-bound plane crashed shortly after taking off from Orly airport and it was later determined that the cargo door detached, which caused an explosive decompression, this caused the floor just above to collapse. The collapsed floor severed the control cables, which left the pilots without control of the elevators, the plane entered a steep dive and crashed. It was the deadliest plane crash of all time until the Tenerife disaster in 1977,329, On June 23,1985, Air India Flight 182, a Boeing 747-237B crashed off the southwest coast of Ireland when a bomb exploded in the cargo hold. All 307 passengers and 22 crew members died, one passenger had checked in as M. Singh

1993 Auckland mid-air collision
–
The 1993 Auckland mid-air collision was an aircraft accident in New Zealand. It occurred on 26 November 1993, when two aircraft operated by Airwork, under contract to the New Zealand Police, collided and crashed in central Auckland, the accident occurred in daylight with excellent visibility, in uncontrolled airspace, with both aircraft flying under visual flight rules. Both the helicopter and aeroplane were operated by Airwork, and working under contract to the New Zealand Police at the time of the accident, the Transport Accident Investigation Commission investigation found the accident occurred because neither pilot saw the other aircraft. The Aérospatiale TwinStar AS355 F1, registration ZK-HIT, was using call signs Police One with air traffic control and it was operating out of Mechanics Bay Heliport, the base of the police Air Support Unit,1 NM east of the central city. At 4,22 pm it returned to the heliport after a mission for a break of about an hour. It departed to the north over Waitemata Harbour and shortly afterwards made a turn to the left to a southwest heading. It flew this course, climbing, for about 1 minute before making a 30° turn to the left, the Piper Archer 28-181, registration ZK-ENX, call sign Pact 1 was flying a regular weekday traffic patrol, piloted by Allan Anthony Connors. The patrols were conducted at 1,500 feet. It left Ardmore Aerodrome at 3,59 pm, and reported on several traffic incidents, shortly after 5,32 pm, the aircraft flew south from the North Shore to a road accident on the Auckland Southern Motorway near the Symonds Street on-ramp. It flew southeast past the accident, and began a turn to the left around the accident site. The aircraft turned through about 270° and was turning through a southwest heading when the collision occurred, the accident interrupted a report the pilot was making to Police Control over the radio. The collision occurred at 5,34,48 pm, near the intersection of Queen Street and Karangahape Road, at an altitude of about 1,400 feet. The left wing of the Archer separated, and the aircraft rolled, dived steeply, the wing landed on a church roof. The TwinStar lost the main rotor and transmission, and rear tail boom, vertical stabiliser and it fell onto the Grafton Road on-ramp to the Northwestern Motorway, under Symonds Street Bridge, and a severe fire broke out, fuelled by 700 litres of kerosene. The main rotor and tail section fell into a cemetery by Karangahape Road, helicopter debris caused moderate facial burns to the driver of a car, who was taken to Auckland City Hospital. The accident created substantial traffic congestion, which hampered emergency services responding to the scene, a witness at Mount Eden,1.3 NM south of the site, caught the accident on video. The Transport Accident Investigation Commission was notified of the accident at 6,20 pm and he began a field investigation later that evening. The wreckage was moved to a storage site prior to inspection, the U. S. Federal Aviation Administration conducted a cockpit field of view survey for the Commission

Mehrabad International Airport
–
Tehran Mehrabad International Airport, is an airport that serves Tehran, Iran. Mehrabad, however, is still by far the busiest airport in Iran in terms of traffic and aircraft movements. It is capable of handling aircraft such as the Boeing 747. The airport is also the gateway used by the Government of Iran. Newly delivered Republic F-84G Thunderjets and Lockheed T-33A Shooting Star arrived, May 1957 and April 1956, in 1955 just after construction of first asphalt paved runway a new terminal building for both international and domestic flights was designed and constructed.
