The speaker, Andy Stumpf, discusses the realism of underwater action scenes in movies, based on his experience as a U.S. Navy Seal for nearly 17 years. He explains that in real-life operations, divers use closed-circuit systems for diving, which are less visible from above but allow them to communicate silently. He also clarifies that divers do not typically fight in the water and that the use of weapons, such as tridents or spears, is not common or practical.
Stumpf explains the importance of proper equipment and training for underwater operations. He mentions that divers often use dive knives for tasks like cutting gear or using the tip to screw in items. He also emphasizes the importance of conserving gas supply and communicating only when necessary during dives.
The speaker criticizes the movie scene where characters use buddy breathing, which requires more than just sitting and breathing together to make progress. He stresses the need for divers to follow procedures and work as a team, regardless of their feelings. He concludes by giving the movie a score of seven, considering the accuracy of the depicted scenarios and the emotional involvement of the characters.
1. Andy Stumpf, a former U.S. Navy SEAL, hosts the Clearing the Fog podcast where he discusses underwater action scenes from movies and their realism.
2. Stumpf emphasizes the importance of cutting away from your shoe before entering the water, as 90% of people killed during a halo jump get tangled up in their shoes and drown.
3. Stumpf shares that he has never been in an underwater fight, but he has experienced equipment trying to kill him, including belts and magnets.
4. He also mentions that most of the diving he did was at night and at depths less than 20 feet.
5. Stumpf shares his observations on the movie's depiction of diving, stating that it's focused on getting from point A to B and is very different from the actual experience of diving in the seal teams.
6. He also points out that the movie's portrayal of exploding propellers is highly improbable, as the best place to put a charge would be on the underside of a vessel, not the propeller itself.
7. Stumpf criticizes the movie's depiction of using white and orange parachutes in the daytime, as it would be an obvious way to reveal one's presence.
8. He also comments on the movie's portrayal of using dive fins on the feet for a free fall jump, stating that it's not how he would do it and it's more likely to tape the fin up to your leg.
9. Stumpf highlights the movie's depiction of using a knife to cut hoses, stating that it's for cutting gear, not for fighting.
10. He criticizes the movie's depiction of a concussive device in the water, stating that it's plausible but you would want to get out of there before it goes off.
11. Stumpf shares his thoughts on the movie's depiction of using an M203 grenade launcher underwater, stating that it's possible but it would probably come out of the barrel and drop off.
12. He also comments on the movie's depiction of jumping off an aircraft carrier, stating that it's survivable and could be done at a height of 50-60 feet.
13. Stumpf shares his thoughts on the movie's depiction of navigating with a nav board, stating that it's a realistic depiction of how divers navigate underwater.
14. He also comments on the movie's depiction of using buddy breathing, stating that it's a realistic depiction of how divers share one air supply between two people.
