This is from a local F15 pilot apparantly

Guys,

I’ve done some more research. This photo shows that Jimmy’s elevator trim tab is apparently missing. If that’s the case, there is some precedent to tell us what might have happened.

The same thing happened to Bob Hannah in 1996 in Bob Button’s Mustang, called “Voodoo Chile” at the time. Hannah’s trim tab came off at 450 MPH, and the airplane pitched up at over 10Gs, popping the tailwheel out and G-LOCing the pilot. He woke up at 9000’ AGL and successfully landed.

10Gs could also explain why the Jimmy’s helmet is not visible in the canopy (the photo I sent in the previous email.) He might have been slumped down below the rail.
