What's the old B&W classic about flying a Ford Trimotor (?) across the
Andes in South America -- flying through a narrow pass in a thick fog.

And the more recent one about the male pilot and female passenger who
make a forced landing on a tropic beach, with no one knowing where they
are; and have to essentially rebuild part of the plane with logs and
rope to get back off. (Or is that one of the one's already mentioned?)
