When I was in the Navy, they used to have a training film they showed us called:
LINK: "The Man From LOX" Training Video
It was directed primarily at young men between the ages of 17 and 21, and it was interesting and comical, to get our attention and keep it throughout the film. It was all about the dangers of working with Liquid Oxygen for planes (LOX)
(If you are offended by sexist training videos, don't watch it!)
The "storyline" is a young sailor working with LOX, who has to get the LOX tank back to a safe location after filling the tanks for the planes. He keeps getting stopped by his buddies who want him to go to the club with them, his parents who magically appear on the flight line and want him to go home with them, or the young woman below who wants him to drop everything and go to the beach with her.
At every stage, he tells the people trying to distract him that he has to bring it back or "The Safety Officer is going to have his ass".
When he gets it back safely, he meets the Safety Officer:
But the very end of it, the last 40 seconds of it or so, is gory and real. Not made up. The story we were told was this young man they showed, who died within minutes after the video was taken, had been working on a hot day, and decided to put the vent nozzle for the LOX dispenser into his coveralls, where the cold, venting liquid oxygen gas filled his coveralls and saturated them. He then took a break to smoke a cigarette, and exploded in flames, fatally injuring him.
We were young guys, all laughing and guffawing at the corny, funny training video, but none of us laughed at that.
And none of us ever forgot it. I talk to naval veterans today, and if they worked in aviation as I did, this film was indelibly etched on their brain.
