Underwater Entrapment - Today's Imminent Warning!

Besides collision and sinking, what are two very ominous incidents for submarine crews?
Entrapment, of course, and getting swept overboard.
But what is actually the Major Cause of most Underwater Entrapment?

Over the last fifty years, around fifteen thousand people have perished due to vehicle entrapment drowning according to numerous sources. ... These people followed the ever shrinking air bubble until it was gone. They died, minutes later. .. It is probable that some of the people that died at the I-35W bridge collapse were trapped inside their car with no other, or minor injuries. They tried their doors and they would not open. They tried their windows, and they would not open. Their vehicles filled with water. As they tried their windows again, the water rose. - Lonny MacDougall, Egression Technologies LLC

How many navy veterans and civilains stationed at Treasure Island, Mare Island or the Navy Airfield in Oakland traversed the Bay Bridge hundreds of times to get home, work, study or for great liberty?
Wednesday, Oct. 28, 2009 - Abolhassan Astaneh-Asl, a civil engineering professor at the University of California, Berkeley who has spent 20 years studying the Bay Bridge, called the initial crack a "warning sign" of potentially bigger safety issues with the bridge.

"The repair they were doing was really a Band-Aid," said Astaneh-Asl, who criticized Caltrans at the time for rushing to reopen the bridge. "The Band-Aid broke, in essence." Astaneh-Asl said the failure of the repair job demonstrates the need for a longer-term solution. The bridge's age and design make it susceptible to collapse, especially if commercial tractor-trailers are allowed to continue using it, he said."I think Caltrans is putting public relations ahead of public safety," he said.
Submarines are always silent and strange.
