The people who made the movie probably read (and licensed!) Nevil
Shute's book "No Highway".

And that book was probably written _after_ De Havilland discovered
metal fatigue, being based on the story of that discovery.

Ah, I see I'm mistaken. Both the book and the movie preceded (1951)
the problems with the Comet (1954). But metal fatigue was actually
discovered in 1837, the name having been coined in 1854. But while
metal fatigue was known, it was still not fully understood - and it
was not anticipated that simply having windows with square corners in
the Comet would cause cracks to develop at their corners under the
stress of repeated pressurization cycles.
