Raymond Michael Mancini, best known as "Boom Boom" Mancini, is an American former professional boxer who competed professionally from 1979 to 1992 and who has since worked as an actor and sports commentator. He held the WBA lightweight title from 1982 to 1984. Mancini inherited his nickname from boxer Lenny Mancini. In 2015, Ray was inducted into the International Boxing Hall of Fame. Mancini, an Italian American, was born Raymond Michael Mancino in Youngstown, Ohio on March 4, 1961. Boxing played a prominent role in the Mancini family history. Mancini's father, Lenny Mancini, was a top-ranked contender during the 1940s. Lenny Mancini's dream, was dashed when he was wounded during World War II. Although Lenny Mancini returned to boxing, limitations resulting from his injuries prevented him from fulfilling his potential. Lenny inspired Ray to develop his boxing skills and encouraged him to train at a gym when he was quite young. Thus, Ray began his quest to win the world title for his father. On October 18, 1979, Mancini made his professional debut and defeated Phil Bowen with a first-round knockout.

His whirlwind punching style caught the attention of network executives at several American television networks, he became a regular on their sports programming. During this time Mancini defeated some notable boxers including former US champion Norman Goins in March 1981. On April 30, 1980, Mancini defeated Bobby Sparks with a knockout at 1:28 in the first round for the regional Ohio State Lightweight title. Over a year on May 16, 1981, Mancini won his first major title by defeating Jorge Morales for the WBC-affiliated NABF Lightweight championship when the referee determined that Morales could not continue after the 9th round. In the post-match interview, Ray said that he was "keeping this title for myself because the world title is going to my dad". Two months he defended the title against José Luis Ramírez after a unanimous decision. Mancini's first attempt at a world title came on October 3 when he was pitted against Alexis Argüello for his World Boxing Council lightweight title; the event was selected by many as one of the most spectacular fights of the 1980s.

Mancini gave Argüello trouble early and built a lead on the scorecards, but Argüello used his experience to his advantage in the rounds and stopped Mancini in the 14th round. Mancini would rebound from the loss to Argüello by winning his next two bouts, including a second successful defense of his NABF Lightweight title against Julio Valdez which would earn him another chance at a world title. On May 8, 1982, in a match held at The Aladdin in Las Vegas, he challenged the new World Boxing Association lightweight champion, Arturo Frias. Fifteen seconds into the fight, Frias caught Mancini with a left hook to the chin and another combination made Mancini bleed from his eyebrow. Mancini dropped Frias right in the center of the ring with a combination. Dazed, Frias got back up but Mancini went on the offensive and trapped Frias against the ropes. After many unanswered blows, referee Richard Greene stopped the fight at 2:54 in the first round, the Mancini family had a world champion. Mancini's first title defense, against former world champion Ernesto España, went smoothly with a Mancini knockout win in the 6th round.

On November 13, 1982, a 21-year-old Mancini met 23-year-old South Korean challenger Duk Koo Kim. Kim had struggled to make the 135 lb weight limit, had to lose several pounds shortly before the fight; the title bout, at Caesars Palace in Las Vegas, was televised. It was, according to many observers, a fight filled with action. Mancini won by TKO in the 14th round. Moments after the fight ended, Kim collapsed and fell into a coma, having suffered a subdural hematoma, died four days later; the week after his death, the cover of Sports Illustrated magazine showed Mancini and Kim battling, under the title "Tragedy in the Ring". Mancini fell into a deep depression afterwards, he has said that the hardest moments came when people approached him and asked if he was the boxer who "killed" Duk Koo Kim. Mancini went through a period of reflection. In addition, Kim's mother committed suicide three months after the fight, the bout's referee, Richard Green, killed himself in July 1983; as a result of Kim's death, the WBC took steps to shorten its title bouts to a maximum of 12 rounds.

The WBA and WBO followed in 1988, the IBF in 1989. Mancini began the process of getting his life back together by once again putting on boxing gloves, he went to Italy to face British champion George Feeney. He defended his title two more times. First, on September 15, 1983, he beat Peruvian challenger Orlando Romero by a knockout in nine rounds at Madison Square Garden to achieve a lifelong dream of fighting in that building, after a November 25 tune-up bout in which he defeated Johnny Torres by first round knockout in his return to the Caesar's Palace hotel in Las Vegas. In January 1984, in a bout with former world champion Bobby Chacon, broadcast on HBO, Mancini defeated Chacon when referee Richard Steele stopped the fight in the third round with blood dripping from Chacon's left eye. In June 1984, still recovering from the emotional trauma of Kim's death, fought Livingstone Bramble to retain his title in Buffalo, New York; this time however, Mancini came out on the losing end, defeated after 14 rounds.

Mancini lost the title, but not before a fierce effort that resulted in an overnight stay at Millard Fillmore Hospital and 71 stitches around one eye. Mancini returned to the ring twice to att

The Curtiss-Bleecker Helicopter was an American prototype rotary wing aircraft, introduced in 1926. The thrust of the aircraft was distributed from a central mounted engine through shafts to propellers mounted on each rotor blade; the Bleecker Helicopter was designed by Maitland B. Bleecker, a junior engineer from the National Advisory Committee for Aeronautics; the aircraft was constructed by Curtiss Wright for $250,000 over the course of four years at Garden City. The aircraft featured a rotary wing design with a single engine; each rotor, painted silver and yellow, had an individual propeller for thrust and a trailing control surface called a "stabovator" to change pitch of the rotor. The aircraft was controlled by a stick. Yaw was controlled with a "Spin Vane" that used downwash from the rotor to pivot the aircraft with foot pedals. Testing on the Bleecker Helicopter was stopped after the failure of a drive shaft on a test flight in 1929. By 1933 the project was abandoned following vibrational issues in further tests.
