Ron Stein (Jr. Officer)
After the Flying Sub is sabotaged, a fire detail, equipped with air masks, dives down the hatch to retrieve Chip Morton and put out the fire. In spite of the fact that the interior is still full of smoke, every one of them takes his mask off before coming back up.
Near the end, Krueger is spotted by Riley and Patterson. As he turns to look back at them, you can see a series of raised spots on the storage closet door, which will be ignited to give the effect of striking bullets. He steps into the closet and they open fire, leaving a diagonal pattern of bullet holes. Crane joins them, and as they start down the corridor, the closet door is clearly unmarked.
Crane: No visual contact, no instrument contact, that thing out there just vanished! Any ideas?
Nelson: Just one: let's get out of here!
Krueger: Gentlemen, I must ask your forgiveness. I am beginning to realize that I have made a mistake. It has taken me until now to realize the fact that there was a basic flaw in my plan. Oh, I could still destroy you by a wave of my hand...but it would be to no avail. I know now that I am .... behind the times. Too far behind. It used to be so much simpler. Everything was so much simpler. So, gentlemen, I apologize, and I leave you to your modern world with all its ... bewildering hardware. I wonder where it will take you.
Both Nelson and Krueger allude to the Flying Dutchman.
There are a number of different references: a medieval legend of a Captain Falkenburg, cursed to sail the North Sea until Judgement Day, dicing with the devil for his soul; a 17 century Dutch Captain, Bernard Fokke, known for the uncanny speed of his sea voyages and suspected of being in league with the devil. The first printed reference is in the 1775 book Voyage to Botany Bay, by George Barrington, concerning a Dutch Man 'o War that was lost "some years ago" off the Cape of Good Hope, seen again by its sister vessel when it returned through the same area. It became known as the "Flying Dutchman". Still another reference is in the May 1821 issue of Blackwoods Magazine, concerning an Amsterdam vessel captained by a Hendrik van der Decken 70 years previously. After a long day of fighting the wind to get through Table Bay, a vessel asked the captain if he intended going into the bay that night, and the captain replied, "May I be eternally damned if I do, though I should beat about here till the day of judgement."
Prince George of Wales (later King George V of the U.K), and his tutor claimed to have seen the "Flying Dutchman" in 1880 off the coast of Australia.
