The flight crews that serviced the B-57s were rotated from Yokota AFB with the 53rd Weather Reconnaissance and the 6091st Squadrons as the B-57s were the staples of the weather and reconnaissance (Tail numbers of three of them were 446,447,448). The RB-57E models had extended wings and overflew Russia and China testing the air after nuclear detonations from 1960-1962. The RB-57s flew so high the SAMs could not reach them. They took the place of the U-2s for a period of time.
Exactly right. I was at Bien Hoa when it happrnrd.
