An NTSB investigator looking at a plane crash. My memory of some of this is hazy. This movie had very odd elements, like him dreaming about being in a plane and seeing cracks developing in the body of the plane. Also, finding an extra arm. Turns out that he's on the plane that crashes.
I don't have any memory of time travel being involved. And, in this one, I think that, at the very end, the NTSB guy is sitting in the airplane, seeing the cracks form and realizing that the extra arm was his and that he's on the plane that's crashing. I've gone through IMDB looking for airplane crash movies and I'm starting to wonder if this was an episode on some tv series like The Outer Limits.
