Feb. 24, 2005 — Today, if you ask the Air Force about UFOs, it will cite its own 22-year study called Project Blue Book, which said there is no evidence that they are extraterrestrial vehicles and there is no evidence that they represent technology beyond our own.
Blue Book, based at Wright-Patterson Air Force Base in Ohio, investigated hundreds of UFO reports yearly throughout the 1950s and 1960s.
...
Blue Book was far from a massive institute with a staff of white-coated lab technicians, said UFO researcher Mark Rodeghier. "There was a guy at a desk and a secretary and a private or someone there typing stuff. It was a very, very small project," he said.
...
Col. Robert Friend, the project's director from 1958 to 1963, told ABC News, "We wanted to explain as many sightings as possible, but we recognized that the amount of resources that would have been necessary in order to do this would have been far beyond those that we were ready to commit at the time."
.....the best way to keep UFOs out of the newspapers — and therefore, out of the public mind — was to say repeatedly that they were nothing more than weather balloons or rare atmospheric conditions, like a star on the horizon.
