Mississippi State University XV-11 Marvel

The Mississippi State University XV-11A Marvel was an experimental American STOL research aircraft of the 1960s. The MARVEL was a single-engined pusher monoplane fitted with a boundary layer control system; the first all-composite aircraft, it carried out its initial program of research on behalf of the US Army in the late 1960s, was rebuilt in the 1980s as a proof-of-concept for a utility aircraft. The Department of Astrophysics and Aerospace Engineering at the Mississippi State University had been involved in a program of research into boundary layer control on behalf of the Office of Naval Research and the US Army since the early 1950s, carrying out trials on a modified Schweizer TG-3 glider, a Piper L-21 and a Cessna O-1. Based on the results of these studies, the US Army awarded the Department a contract to develop a new STOL research aircraft the XV-11 MARVEL; the resultant design was a shoulder-winged monoplane powered by a single Allison T63 turboprop engine driving a pusher ducted propeller.

The aircraft's structure was made of fiberglass, making the Marvel the first example of an all-composite aircraft. The boundary layer control system used a blower driven by the engine to draw suction through more than one million tiny holes in the wings and fuselage, while instead of conventional flaps the Marvel used a form of wing warping to deflect the wing trailing edges to vary the wing's camber; the aircraft's tail surfaces were attached to the duct around the propeller, extending behind the duct. The undercarriage, of the so-called "Pantobase" configuration, with tandem wheels fitted within two sprung wooden pontoons, was meant to allow operation from rough surfaces, or from water, it was constructed of fiberglass, with steel used for reinforcement and as heat shields around the engine. The aircraft's wing and ducted propeller were tested on a piston-engined test bed, the XAZ-1 Marvelette; the full-sized Marvel was built by the Parsons Corporation based at Traverse City, making its first flight on December 1, 1965.

It completed a 100-hour flying program for the US Army in 1969, where it demonstrated good STOL performance, taking off within 125 ft, although the boundary layer control system was not as effective as hoped, it still provided a large amount of test data. Following the completion of the US Army testing in 1969, it was sent to storage awaiting further tests; the Marvel was brought out of storage as a proof-of-concept demonstrator of a STOL utility aircraft for Saudi Arabia. It was fitted with a more powerful engine and longer span (36 ft 10½ in wings, first flying in this form as the Marvel II on August 17, 1982. After initial tests in the United States, the Marvel II was shipped to Ta’if, Saudi Arabia, carrying out a short test program which showed that its landing gear was unsuitable for operating from soft sand and it was still underpowered, after which it returned to Mississippi. In 2000, the aircraft was displayed at EAA Airventure promoting the Mississippi State Department of Aerospace Engineering.

In 2004, the XV-11A was donated to the Southern Museum of Flight at the Birmingham International Airport in Alabama.

WBZA is an adult hits station in Rochester, New York, broadcasting at 98.9 FM. It is owned by Entercom Communications, who purchased the station from Sinclair Broadcasting in 1999. Before its current format, the station played oldies as WBBF before that station moved to a lower-powered station broadcasting on 93.3 FM. The station's studios are located at High Falls Studios downtown, its transmitter tower is on Rochester's west side; the 98.9 frequency in Rochester has been in continuous use since 1946. Before signing on at its current frequency, the direct predecessor of WBZA known as WHFM, broadcast in the old 42-50 MHz FM band. Founded as a sister station to WHAM by Stromberg-Carlson, its daily operation dates back to 1939, making it one of the oldest surviving FM stations in the United States; as WHFM, the programming format was top 40/CHR from the late 1960s until early 1985. In early 1985 the call letters were changed to WZKC, the format changed to country music. In the summer of 1986 both format and call letters were changed again, with WKLX adopting a classic hits format.

In April 1988, the format was changed to "classic oldies" and at the same time the transmitter site was relocated into the city of Rochester. It took on the WBBF call sign in 1998. In November 2000, WBBF's intellectual property moved to then-sister station 93.3 FM, 98.9 flipped to all-80s hits as "The Buzz." This continued until 2004, when it shifted while retaining the "Buzz" moniker. With the demise of hard rock station WNVE in 2007, WBZA shifted from classic rock to mainstream rock at the same time when Entercom purchased classic rock station WCMF from CBS Radio; the callsign had been that of WBZ's sister station in Boston, established in 1924. Following the closure of WBZA in Springfield, the call letters were assigned to an AM station in Glens Falls, New York; that incarnation of WBZA broadcast on 1410 kHz with 1,000 watts of power. The station had signed on in 1959 with the call letters WSET. 98.9 The Buzz - Official website Query the FCC's FM station database for WBZA Radio-Locator information on WBZA Query Nielsen Audio's FM station database for WBZA
