"We now conclude our broadcasting day." Historical film of "High Flight". A poem by John Gillespie McGee, Jr. The local TV station WHIO in Dayton, Ohio used to sign off the air for the night immediately after airing this film clip in the early 1960's. Since there was a USAF SAC bomber B-52 wing based at Wright-Patterson AFB there in Dayton it was truly fitting during the cold war to remind us all that the Air Force never sleeps.
