Have you ever heard of MPATI? - The Midwest Program on Airborne Television Instruction? If you answered NO, read on! If you answered YES, well to be honest, I probably don't believe you, so read on anyway!
The following is from Wikipedia -
Midwest Program on Airborne Television Instruction. (2009, December 9). In Wikipedia, The Free Encyclopedia. Retrieved 22:12, August 25, 2010, from http://en.wikipedia.org/w/index.php?title=Midwest_Program_on_Airborne_Television_Instruction&oldid=330741975
The Midwest Program on Airborne Television Instruction (MPATI) was a special broadcasting initiative designed to broadcast educational television programming to schools, especially in areas where local educational television stations are either hard to receive or unavailable.
The undertaking began as a three-year experiment in 1960, with MPATI organizing, producing, and broadcasting instructional television with seed-money from the Ford Foundation. This was a nonprofit organization of educators and television producers that pioneered instructional television for enriching education in public schools throughout the midwest. This was in times prior to the advent of satellite television transmission. By 1963, MPATI moved into its second phase where it relied totally on membership fees but it was never financially stable. MPATI found it difficult to get enough member schools to finance the organization. In its third reorganization, MPATI, unable to meet its expenses through membership fees, ceased producing and broadcasting courses in 1968 and became a tape library.
One of the two aircraft would go aloft for six to eight hours at a time; take up a twenty minute figure-eight station centered over Montpelier, Indiana (35 miles north of Muncie, Indiana) at an altitude of 23,000 feet. From this position the range of transmission was approximately 200 miles in diameter; stations transmission included both Chicago and Detroit metropolitan areas. When on station the plane would reduce speed, and then lower a forty-foot antenna mast which was gyroscopically stabilized so that the antenna always aligned from the aircraft to the center of the earth. This stabilization feature helped to maintain polarization of the signals from these planes. Beam characteristics of the antenna were sharp and reception was optimized by placing the reception antenna as near as practical to the ground and pointing it toward the Montpelier location to minimize multipath canceling and interference.
Programming from the planes was always pre-recorded; program slates, taped classroom instruction and test patterns with canned music were all that was aired from the MPATI planes. Frequently snowy pictures were what students saw from the low power transmitters of KS2XGA or KS2XGD channels 72 and 76 UHF respectively.
The television equipment and transmitters were powered by a gas-turbine electrical power plant in the aft end of the DC-6 fuselage; equipment similar in design to auxiliary power units later jet transport aircraft use for engine starting.
