Will A.Net reconsider the Lockheed D-21 drone? This was carried by the A-12 as project 'Tagboard' and later the B-52H as project 'Senior Bowl'.
There is just one photo which has been in the database for some years now taken by AirNikon yet my several attempts to upload photos since have been blocked using the ubiquitous 'Motive' rejection. I cannot believe that I have been the only uploader given how many are now preserved in the USA.
As a comparison A.Net was perfectly happy to accept the Gyrodyne QH-50C Dash which was a drone conversion of the H-50 flown from destroyers for anti-submarine warfare, being armed with two Mark 44 acoustic homing torpedoes.
The D-21 really was the Grandaddy of the current recon drones and, IMHO, as such deserves a place on A.Net.
