I have not had a third party conformation of this, yet.
Just had an amazing story told me. Here is the new M-22 Mustang, at it's maiden press release. The members of the press were assembled, the Mustang shined up and ready. The test pilot was at altitude. There were two Com's set up, one for the public, and one inside the hangar. The story goes like this, " I've reached FL20 and all is well" "Kerrville, we have a problem" Seems there was some kind of engine fire. The Pilot empty's the fire extinguisher. Get's the fire out. He then proceeds to deadstick the bird onto the short runway, and rolls it to the hangar doors on momentum alone. The legend is that the pilot got out of cockpit, waived at the crowd, and walked inside.
Again, I don't have this verified. I asked my father and he does not remember it happening. I will ask and try to get it verified.
