Years and years ago I saw some old black and white newsreel footage showing a bathysphere which, I suppose, had suffered some sort of mishap and filled with water while it was submerged. The footage showed the big diving ball on a pier or the deck of a ship while some guys popped open a small window or hatch. Water shot out of the opening like a fire hose!
What the heck was I seeing, and what were the circumstances and date of the incident? Anybody know?
It was the testing of the first deep sea diving “bell” and it leaked. It filled with water under pressure so when it was brought up and the bolts around the window removed the water shot out like a cannon.
