There were some things I didn't remember, like the disco dancing scene. There were some lines that I didn't realize/remember came from the movie--"Roger, Roger, what's our vector Victor?" and "Don't call me Shirley."
The movie was so simple in its mockery. I don't think this film could be made today. I think it would get mucked up with special effects, political correctness, and bad acting.
Airplane! was still funny. I'm glad we went.
