On 11/30/71, SA THOMAS J. MANNING advised that
investigation conce-rning the suspect aircraft now discloses
that it could be a TR-6 instead of a Cessna and that both
kinds of aircraft should be considered. He said a TR-6
was a World War II training plane and that several of them
are still being used.
