B-29B Superfortress (Stratovision)Stratovision was a system to rebroadcast TV and FM radio signals via transmitters mounted on airplanes. The idea was first proposed in 1944, and by September 1946, engineers had a workable design, first tested over Baltimore in a PV-2. Martin modified B-29B (44-84121) for testing Westinghouse engineer Charles Noble's concept. On 23 June 1948, the B-29 crew, orbiting 25,000 feet above Pittsburgh, re-broadcast the Republican National Convention directly from WMAR-TV in Baltimore. The B-29B was outfitted with an 8 foot mast on its vertical stabilizer to receive programs. The signal was sent from the antenna to the cabin, and then to the broadcast antenna which was stored horizontally in the bomb bay & extended 28 feet vertically when operating. Testing wrapped in 1949 and Westinghouse dropped Stratovision in 1950. Purdue University later experimented with the same idea using two DC-6Bs to broadcast non-commercial eductaional TV programs under the Midwest Program on Airborne Television Instruction program in the days before satellites & cable TV in the Midwest from '61-'68. Stratovision technology was used by the U.S. Navy from two Project Jenny NC-121Js (BUNO 131726 & 131641) during Operation Blue Eagle from 1966 to 1972 to provide television service to the Saigon on channels 11 (in English) and 9 (in Vietnamese), plus radio stations on AM 1500 and FM 99.9. A third aircraft (128444) at DaNang provided airborne PSYOPS radio broadcast services for MACV-SOG. These aircraft were the forerunners of Coronet Solo & Commando Solo (the 193 Special Operations Wing the PA Air National Guard) which still flies PSYOPS missions today in their EC-130s.<img src="https://scontent.faep8-1.fna.fbcdn.net/v/t31.0-8/27021682_1827830897262193_43460404727619_o.jpg?oh=fd6be8022ff77974f20304f606b3f94b&oe=5B20852A" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="https://scontent.faep8-1.fna.fbcdn.net/v/t1.0-9/27332306_1827835663928383_3324483798995306072_n.jpg?oh=4d3c85a4cb2f25c9ef8dc0fdf233b0cb&oe=5B23B541" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="https://scontent.faep8-1.fna.fbcdn.net/v/t31.0-8/27021681_1827890783922871_5253175296749377945_o.jpg?oh=bf9b3902da8e92135d82178f6db6346b&oe=5AF23816" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="https://scontent.faep8-1.fna.fbcdn.net/v/t1.0-9/27072453_1827891127256170_8786424623682546969_n.jpg?oh=22192a0b703e4aaa61ea710bae79ebdf&oe=5ADB6665" alt="" class="fr-fic fr-dii fr-draggable " style="" /><img src="https://scontent.faep8-1.fna.fbcdn.net/v/t1.0-9/27336212_1827891330589483_2123674748511592436_n.jpg?oh=5467a46161058405a3f149ce460fb9ea&oe=5ADEABDF" alt="" class="fr-fic fr-dii fr-draggable " style="" />del FB de Detail & Scale ...</blockquote>
