Allen Hynek gave many talks and genuinely enjoyed doing so. He was a natural teacher and a presenter who had a fascinating topic to discuss. He lectured around the globe on UFOs, during his Air Force consulting days and afterwards.
This is a the written version of a talk presented to the Hypervelocity Impact Conference Banquet at Eglin Air Force Base in Florida, April 27, 1960.
The American Association for the Advancement of Science held a symposium on UFOs on December 26–27, 1969. This is Hynek’s contribution recapping his 21 years studying UFO reports at that time.
