Airplane was also a spoof of the film
Zero Hour. I don't believe the reviews at imdb. The only reason i watched it was because of Airplane. Zero Hour was a very B movie.
There was a TB Movie of the week made back in the 70's called
"Terror In The Sky" with Doug McClure and Roddy McDowell. Both are based on the Arthur Hailey novel
"Runway Zero-Eight"
Actually, its not that bad....
