It is extremely rare that a UFO incident would end up in the United States government being sued by two citizens. On December 29, 1980 just outside of Dayton Texas petty cash and Vicki and Colby Landrum were returning home from dinner. The witnesses saw a diamond-shaped aircraft burst into flames radiating heat while struggling to remain aerial. As the witnesses watched the craft eventually righted itself returning to higher altitudes where it was surrounded by helicopters identified later as tandem rotor CH – 47 Chinooks. Unfortunately all of the witnesses experienced health problems similar to ionizing radiation and sued the government for $20 million. The case was dismissed for lack of evidence that the helicopters, in question, ever belonged to the government.
