Researchers are in the struggle To understand why a military helicopter and a passenger aircraft were located in the Potomak River in Washington, DC in late Wednesday, the first large -scale US air crash in 16 years.
From a slight known, human error is likely to be involved and raises questions about the chronic shortage of air traffic controllers and pilots. Officials may also seek coordination between military and civilian air transport.
A UH-60 Black Hawk army helicopter, which has three soldiers, apparently plowed into a Bombard CRJ-700 from Vichaita because it was less than landing at Reagan National Airport. The remnants of both aircraft fell several hundred feet into the shallow and the ice river.
The passenger jet, run by PSA on behalf of the US Airlines, had 64 people on the aircraft and previously recovered 27 corpses. The last tragedy of this deadly plane in the United States was the collapse of Colgan Air in New York State in 2009.
The helicopter may have been removed from a military base near the airport. In a thick film from the center of Kennedy, a smaller light, possibly a helicopter, can be seen over the brighter light of the aircraft, both of which were low -flying to the ground. The two collide in a huge explosion and are divided into several scorching pieces.
A few minutes before the arrival, air traffic control asked the US aircraft to fly a shorter band in the 33 band. The pilots said yes, they apparently replaced the band during their approach. Some of them have been wondering if this change in the flight can remove the Black Guard.
But John Tichrt, a retired Air Force Brigade, told NewsNation that this should not be an accident. “I think that while they were told to change the airport runway, this is not an offensive maneuver in an area jet that would change them again and be surprised to the black hawks,” he said. “
Marco Chan, a former pilot, who is currently head of experimental programs at the new Buckinghammashire University, told Wiried: “
“Safety protocols may be playing human factors,” he says. “I do not like to conclude sooner. Generally, worldwide, after the epidemic, while the number of passengers is slightly back, I don’t think the number of workforce is gathered in any aspect of air transport . ”
Air traffic control asked the helicopter if he had seen the aircraft, and was told to “cross behind the crj”, which had the right to the road unless the Black Falcon was in an urgent military mission. It is unclear whether the helicopter has responded.
Military flights sometimes work in different radio frequencies compared to passenger flights, so the passenger jet crew may not have heard that the radio tower is Black Hawk. Or there may be a gearbox: If more than one side on a channel is simultaneously radio, it can prevent others from hearing the whole conversation.
