All I see is a minus sign in a circle (no picture)

Default gopro

Would have loved to see the gopro footage of this - doubt it exists unfortunately. Amazing.

Default Congrats to the awesome pilot!

Absolute miracle that it allowed a clearly excellent pilot to land! Well done!

It looks like the right elevator buckled (1st), an 8 elevator has failed like this and was posted here with pictures. I thought the Rockets had the H bars extended into the front spar more. It will be interesting to hear the experts evaluation of the parts if they get posted.

Sure glad it did not end like the 7's with inflight failures.

It will be interesting to see what caused this failure. The r/h stab spar webs seem to have failed in an aft direction, however the anhedral of the l/h stabilizer would indicate negative g loading. It is quite amazing this guy was able to get this thing on the ground in more or less one piece. Glad everybody is OK.

In a positive G loading, isnít the tail loaded down?

Yep -- but we don't know the condition when the failure occurred. We only can see the condition now, in the hangar, following (perhaps) some maneuvering to make the airport. So it's premature to attempt to analyze this event.

I'm darn glad and amazed that they made it back. Those folks are good.

I totally agree. .I wasn't stating that the position now is representative of the forces at play that caused the failure.
I do have a question for the experts out there. .This looks like a standard RV8 empenage, right? You can see the Hs-810 and HS814 angles, I thought the rocket tails had more parts than a standard 8 tail? Were the original rockets with a non balanced rudder?

The F1 empennage is not a standard -8 tail. If you look carefully at the original Flickr pics you can see the elevators have riveted trailing edges. Also, I believe nothing is pre-punched on the F1 tail.
