here is the excerpt I gave him...
------------------
The D-21 was designed to carry a single high-resolution photographic camera over a preprogrammed path, then release the camera module into the air for retrieval, after which the drone would self-destruct.[1] Following a fatal accident when launched from an M-21, the D-21 was modified to be launched from a Boeing B-52 Stratofortress. Several test flights were made, followed by four unsuccessful operational D-21 flights over the People's Republic of China, before the program was canceled in 1971.

We've done similar things...just a little faster than a balloon. I trust we'll reach an understanding.
