Content Description The Ray L. Streich B-47 Flight Checklist is a small collection consisting of the flight checklist used by Lt. Col. Streich during his service with the U.S. Air Force. The B-47 flight checklist was printed in December 1959 but includes some pages dating to 1957 and 1958. There are handwritten annotations throughout and some small notes enclosed. An undated report, "Last Resort Type Bombsight," developed by the Strategic Air Command was folded and inserted into the manual.
