Corso Quotes about the San Augustin Crash

1997 - Art Bell Show with Linda Howe, from Roswell

Q. Art Bell: Did the alien tchnology you worked on come from Roswell?

A. Corso: It was from Roswell, but sometimes I get the idea that some of it may have come from the San Augustin crash.

Philip Corso videotape interview with Ted Loman, for Laughlin conference, 1997

Q. Loman: Were you privy to any other crash sites in Arizona, New Mexico?

A. Corso: I was privy o the San Augustin crash and one other crash right down south in Mexico. There were two crashes I was privy to in this area...and there were others.

Loman, again questioning Corso

Q. Loman: That San Augustin crash...could that have been crashed at Socorro instead of San Augustin, in that area?

A. Corso: No, it wasn't Socorro; it was down on San Augustin. I got a map and Roswell went through my area.

(Note: in 1957, Col. Corso was stationed at the Red Canyon test firing facility at the north end of the White Sands missile range. Lining up the Roswell site with the old A-bomb (Trinity) site with the Plains of San Augustin, implies that Col. Corso may have had knowledge of a connection between the Roswell and San Augustin crashes.)

George Knapp, investigative journalist, speaking of Corso's integrity to a large audience in 1997, said:

"What do you make of Phil Corso? Bottom line, I think he's telling the truth...".........."I have found him to be charming, articulate and honest...".........."He is blessed with a good memory and a sense of honor as well."
