I did do a search, but I didn’t see anything mentioned about this…
First, let me say the movie was kinda crappy, but had my curiosity piqued only because it was based on ‘true events.’
My question is, after all these years, did they ever find out what caused the bridge to collapse in Point Pleasant, W. Va. on December 15, 1966?
Never mind - I found this (and apparently it occurred in 1967):
Carry on.
