In the 70's I saw a movie on TV about an investigation into flying saucers.
It was a bit like a docudrama, and might have been a made for TV movie.

I remember: a small plane crash caused by a ufo. Aliens looking like us but with a translucent skin. One of them found dying in a wooden hut, apparently because one of us died. A flight in a small plane over a rocky area with a bright light on the ground from a landed saucer. A smashed film camera as the remains of a reporter that got too close.
And that's about it.

It is not the 1956 UFO the true story about flying saucers, and I can't find it on IMDB.

Anybody knows what movie I am talking about?

Some suggestions:

"UFOs are Here!" (1977)

"Phantom From Space" (1953)

"Unidentified Flying Objects: The
True Story of Flying Saucers" (1956)

"Invasion: UFO" (1972)

"The Disappearance of Flight 412"
(1974)
