In 1947 a U.S. government survey found that only 10% of Americans thought that UFOs were really spaceships from other planets. In 2006, another survey asked similar questions and found that 24.6% of Americans thought that UFOs were E.T.I.
Most Americans believe that those lights and strange sightings are a result of their government experimenting with (and hiding) aerospace technology. Credible sources (i.e. astronaut Gordon Cooper) make UFO phenomenon hard to dismiss.
