Thanks Ulric
Thanks Ulric, indeed an interesting read, and at a minimum those are by far the best photos of the flaperon I've seen. I gather this is an unofficial effort by someone with expertise who only had access to publicly available photos. It's too bad he didn't have access to the flaperon, I'm sure a close look at that trailing edge would allow a determination whether it was flutter or impact that broke it off. I agree with Oleostrut and AirLandSeaMan, the flutter fail mode is my best guess. Feint to the NW, final turn S toward the middle of nowhere, hypoxia, fuel exhaustion, spiral in.
