Viewers watching 'The Falcon and the Snowman' on HBO saw the film replaced by a color-bar test pattern and a message: 'GOODEVENING HBO FROM CAPTAIN MIDNIGHT $12.95/MONTH ? NO WAY ! (SHOWTIME/MOVIE CHANNEL BEWARE!)'. John R. MacDougall, a 25-year-old operations engineer at an uplink station in Ocala, had beamed his own signal at the Galaxy 1 satellite, overpowering HBO's. The stunt exposed how vulnerable satellite television was, and it led Congress to make satellite hijacking a felony.
HBO had begun scrambling its satellite signal earlier in 1986, and owners of backyard dishes, who had been watching for free, were now asked to pay $12.95 a month for a decoder subscription. John R. MacDougall, who also sold satellite dishes and had watched his business suffer, worked the late shift at Central Florida Teleport in Ocala. Shortly after 12:30 a.m. Eastern time, alone at the station, he aimed its transmitter at Galaxy 1 and swamped HBO's signal with his own.
For four and a half minutes, viewers across the eastern United States saw his text on screen. HBO's engineers noticed but could not override him until he stopped transmitting. The Federal Communications Commission began a methodical search, narrowing some 2,000 licensed transmitters to the few hundred uplinks powerful enough to do it, then to a dozen. The break came from an accountant who overheard a man bragging about the stunt at a rest stop and noted his license plate.
MacDougall pleaded guilty, paid a $5,000 fine and served a year of unsupervised probation. The episode shaped the Electronic Communications Privacy Act of 1986, which made satellite hijacking a felony punishable by up to ten years in prison, and pushed the industry toward systems that automatically identify every uplink transmitter.
