Good Morning America: How to escape from a car sinking in water

Vehicle submersion expert Gordon Giesbrecht and Sgt. David Ploog of the Indiana State Police joined Gutman for the live demonstration, which included multiple safety measures, including an ambulance on standby, rescue divers in the water, a broken back window as an emergency exit and a tow team in place if needed.

Before the demonstration, Giesbrecht, who is also a professor of thermal physiology at the University of Manitoba in Canada, explained that water pressure can greatly impact one’s chance of survival.

“When the water is even a foot or two above the bottom of the door, there’s like up to 500 pounds of pressure. That’s very difficult to push against,” Giesbrecht said.
