In the awesome 1980 comedy Airplane!, there are two jokes that make no sense and I've never been able to find an adequate explanation for them. Is anyone able to shed some light?
Near the end of the film, Rex Kramer (Robert Stack) arrives at the control tower to help Ted Striker (Robert Hays) land Trans-American Airlines' endangered flight 209. Kramer confers with Lloyd McCroskey (Lloyd Bridges) and, while they're discussing the situation, they have the following exchange:
McCroskey: Right now, things aren't so good.
Kramer: Let me tell you something, Steve. Ted Striker was a top notch squadron leader. A long time ago.
At that moment, a spear whizzes across the room and into a nearby bulletin board. Without referencing the projectile, the conversation continues:
McCroskey: I want you to get on the horn and talk that guy down. Now you're going to have to let him get the feel of that airplane on the way and you'll have to talk him onto the approach. So help me, you'll have to talk him right down to the ground.
At this point, a watermelon drops from above and smashes onto the corner of a desk in the background. It is not acknowledged by either character.
Everything else in the movie is crystal clear, but these two gags have always confounded me. Surely somebody must know!
