It’s kind of hard to compare the two. Monty Python relies on silly situations, whereas Airplane used more serious situations with literal re-interpretation.
Airplane had a lot more english wordplay, delivered completely deadpan. A lot of the script was taken from a serious airplane drama (so much that it was licensed), and many the actors were serious actors that had never been in comedies before, including Leslie Neilson.
"Surely you can’t be serious!" "I am serious, and don’t call me Shirley."
You keep spelling it wrong. It’s Airplane!
The punctuation is part of the title.
