Water: Cockpit and Dilbert Dunker

water: During the Second World War, many fliers died after ditching at sea because they were disoriented underwater and couldn't escape from the cockpit, according to Globe and Mail. So Lieutenant Kaneb, of the U.S. Navy, led a team of engineers to build a survival-training device: They came up with a simulated aircraft cockpit on rails perched at a 45-degree angle above a pool of deep water. His biggest claim to fame, however, is his wartime invention of the Dilbert Dunker, a gizmo designed to save the lives of U.S. air crews. A trainee would be strapped into the cockpit and then the Dilbert Dunker would be released, dunking the student under water. To add to the challenge, the cockpit would invert upon hitting the water. The trainee had to struggle to get out. (www.immigrantscanada.com). As reported in the news.
