I remember the line from the guy on the ground, as they pulling the sheet over his face, "I'm not dead yet!"
I guess that was the 1st disaster film spoof, though not the best. I still woulds like to see it again. The thing is, it spoofed disaster transportation films in general, while Airplane spoofed a particular film, THE BIG BUS -- wait a minute! there is a link to a NEOPLAN JUMBOCRUISER on the Wikipedia page!

Somebody really did mage a huge bus!
Anyway, so I had seen the Poseidon adventure, & that was about it, until much later.
I did see the [
Zero Hour] airliner disaster film, on TCM a few years ago, & had not seen
Airplane itself in full until TCM ran them both one after the other, though Airplane was 1st! So, for those seeing Zero Hour only after seeing Airplane, I can imagine them laughing at a totally serious movie, because item for item, Airplane spoofed it.

But even seeing Zero Hour before Airplane, I could not help thinking S. Haydon's character was General Ripper, whom he played in Dr. Strangelove.
While I cannot recall much specifics from THE BIG BUS, I suppose it did spoof airline disaster films.
