AF intercepts UFOs over DC in 1952

So said The History Channel’s Ancient Aliens, with one of the program’s experts stating Air Force “F-93s” made the interception.

F-93? I didn’t remember that number as part of the Air Force inventory.

“On 9 June 1948, the USAF ordered 118 F-93s, but the order was cancelled a year later.”

“In 1949, the production order was abruptly canceled as priorities had shifted dramatically following the testing of the ground-breaking Boeing B-47 which reputedly would not need an escort due to its high speed capabilities.”

It’s a small thing, giving credit to the wrong aircraft. But … Small wrongs in an alleged history program add up to wondering what else did the researchers and writers and experts get wrong?
