I would imagine that they had interesting spin

I think it was Eric Brown who wrote about flying the British all-wing
aircraft, and having it almost rotate backward on him.

This is probably exactly what happened to the YB-49 that crashed near
Muric (now Edwards AFB) killing the pilot Danny Forbes, co-pilot Glen
Edwards, and the crew.

There are two files on the Warbird's Forum consisting of interviews
with Robert Cardenas, the military test pilot after Edwards, and a
very different view from Northrop test pilot Charlie Tucker
