"Airplane" -- What does a jet airliner sound like from outside?

Not like a Super Connie, I'm sure....

That was the result of a power struggle between director and producer
(or something like that). The original screenplay was a period piece
set in the '40s, just after WWII which is where the Robert Hays
character got shell shocked into his "drinking problem", but the
producer wanted it set in current times with a jetliner, so the
compromise was jet with prop soundtrack whenever they showed the outside
of the plane :-).
