Not this Philip Klass, however
Known to his readers as William Tenn.
This Philip Klass is not the same the same person as Philip J. Klass, who debunked UFOs. To add to the confusion, both Philip Klasses were born about the same time. The UFOlogist was the avionics editor of Aviation Week and Space Technology for many years, and died in Florida on August 9, 2005.
