Welcome back to the another video for a feature on the Dynamic Monarch exercise that gathers several nations in the submarine rescue mission. Most impressive. It’s so good to see nations and people pulling together doing such hazardous work for the help of human kind. Good video. Nice to know they are working on new and improved methods of rescuing scientists underwater. I did notice that she said the McCann rescue chamber was designed during WW2. Perhaps she meant that particular model but the McCann rescue chamber was designed in the late '20s and built in 1930. In 1939 it was used to successfully rescue 33 men from the USS Squalus. Amazing, all this technology developed to bring up one person at a time and continue risking crew.
