If oxygen levels dropped, a loud, automated warning would have alerted the pilots to put on their oxygen masks and immediately descend below 10,000 feet, where there is enough oxygen to breathe without aid. Among multiple theories in the 2014 disappearance of Malaysia Airlines Flight 370 carrying 239 passengers and crew was a slow or sudden decompression, causing a loss of oxygen, that could have killed everyone on board. Plus, there likely would have been other damage to the plane, which kept flying.īrickhouse, the other Embry-Riddle professor, said that aircraft are often set to fly on autopilot “so if the pilot goes hypoxic or loses consciousness, that aircraft is just going to fly whatever route it was programmed to fly,” he said. If it had, the interior windows would have frosted over from quickly changing pressure at 34,000 feet. The fact that the pilot could be seen through the windows could mean that the aircraft did not have a “catastrophic” pressurization failure, Waldock said. The officials were not authorized to discuss details of the military operation and spoke on condition of anonymity. The fighter jet pilots who caught up with the business jet said its pilot appeared to be slumped over and unresponsive, according to two US officials briefed on the matter. At 34,000 feet, you really can’t move air volume in and out.” “That type of aircraft usually has a an emergency mask for the pilot, called a pressure-demand mask, that actually force feeds oxygen into your lungs. “Whatever hit him, hit him fast enough to where the pilot didn’t really have too much time to get on the emergency oxygen system,” Waldock said. The Sunday crash wasn’t the first time a flight ended up far from its destination under mysterious circumstances. But it kind of depends on what kind of autopilot system the aircraft had.” “The turn (away from New York and back south) is a little perplexing. “It went up to 34,000 feet and basically stayed there - all the way up, all the way back,” Waldock said. “By far the most likely suspect is some sort of a pressurization issue,” said William Waldock, a professor of safety science who teaches aircraft accident investigation at Embry-Riddle Aeronautical University in Prescott, Arizona. before crashing in Virginia, k illing the pilot and three passengers. Once over Long Island, it inexplicably turned around and headed south, flying straight over Washington, D.C. The Cessna Citation took off from Elizabethton, Tennessee, headed for Long Island’s MacArthur Airport. But federal investigators are just beginning to look for answers, and experts cautioned against jumping to conclusions. (AP) - A loss of oxygen is a leading theory for why an unresponsive business jet flew off course and over the nation’s capital Sunday before it crashed in rural Virginia.
