None.

Slapstick content throughout.

Planes often crash, explode, and getting destroyed in as many ways as ever possible. As a result, the main characters often fall to the ground, but never get injured or killed. It's all played for comedy.

Occationally, characters are attacked or beaten by other characters. Again, all played with comedy.

The main plot of the show involves the main characters using planes to attack a pigeon, in order to stop him.

Dick Dastardly often calls other characters by words like "dumb heads", "knuckleheads" and more.

Dick Dastardly often mutters "drat and double drat" whenever a failure happens.

Only one brief scene of a man smoking a tobacco.

This is a very comical cartoon show, even though the show often features planes getting destroyed in as many ways as possible.
