Deliberate mistake: David spots the boat with the old folk on and runs around the harbor, down the jetty and jumps towards the dive boat as it leaves the jetty. He doesn't jump very high and you can see he would miss the rail on the boat. In the next shot, a (larger) stunt double is shown leaping high in the air onto the boat and, of course, catches the rail.

Mary Luckett: Well I for one don't believe any of this alien crap.
Alma Finley: You mean you don't believe your husband?
Mary Luckett: No, I don't believe him.
Alma Finley: Well I believe him and I'm scared.
Bess McCarthy: Well I don't believe him and I'm still scared.
Trivia: Some of the cloud effects were created by dumping colored dyes in tanks of water which were then superimposed into the shot.
