On April 28, 1956, in New York City, Frank Edwards was a featured speaker at a public meeting by The Civilian Saucer Intelligence of New York ufology group. It was actually the first time Frank Edward publicly talked about UFOs.
The Civilian Saucer Intelligence used to publish written reports of what was said at their publich meetings.
After his lecture, there was a session of questions and answers.
A member of the audience asked:
Q - Is there any evidence that any of these objects have crashed?
Frank Edwards replied:
A - I'm not too sure some of them haven't. Way back in 1947, at Roswell, New Mexico, a farmer reported he saw something strike a mountainside and crash. According to what I was told, they threw troops in a circle all around that place, and would let nobody in for five days. Finally they came up with a picture of a man holding a little crumpled kite with aluminum foil on it --- a radar target --- they said this was it --- believe it or not. There have been many other rumors since then of saucers having crashed. I don't know whether there's any truth in them.

Frank A. Edwards (1908-1967) had been a pilot, then one of the pioneers in radio hosting in the United States in the 1920s to the 1950s. Late in his life, he became also famous for his two popular books about UFOs: "Flying Saucers - Serious Business", 1966, and "Flying Saucers - Here and Now!", 1967.
It is obvious here that Frank Edwards knew more of the Roswell incident than expected, as he gave details that had not appeared in any 1947 newspapers or sources.
