[aircraft] Lockeed Martin M-21/D-21 (1969)


Well-Known Member
A combination among a mother vector (''M'' stands for ''mother'') and a remote control little plane (''D'' stands for ''daughter''). The production was suspended in 1971 because of the high costs and the few results reached. This has been successfully replaced by the SR-71 blackbird.
