Nose art pays tribute to B-52’s top secret past
An information plaque for a D-21 reconnaissance drone on display at Blackbird Air Park at U.S. Air Force Plant 42 in Palmdale, California. The D-21 was a ramjet-powered reconnaissance drone that could reach Mach 3 speed. Ideally, the drone would air launch from a mothership and after conducting its reconnaissance mission it would eject a hatch with photo equipment to be recovered either mid-air or after the hatch landed.
