Nose art pays tribute to B-52’s top secret past
A B-52 currently used for testing by the 419th Flight Test Squadron, sits on the flightline at Edwards Air Force Base Oct. 16. The bomber, tail# 60-0036, was used in a top secret test program that began with the code name Tagboard. The program involved testing the D-21, which was a ramjet-powered reconnaissance drone that could reach Mach 3 speed. The D-21 would be launched from underneath the wings of the bomber.
