Washington -According to the expert's observer and officials, large -scale air safety disorders and mistakes in the last arbitration have caused the death of 67 people across the Potomac River on Thursday night.
Late on Wednesday, the American Airlines 5342 from Wichita, Kansas, dropped crash with the Army UH-60 Black Hawk Helicopter, only 400 feet of the historic Washington DC Waterway.
Bombardia CRJ700 Regional Jet (60 passengers and four crews are on board), when approaching the Ronal Dragan Washington National Airport, explodes with fireballs, invades three pieces, and “white” or “white.” I put the night sky on the night sky similar to “flare”. Witness on the ground.
Since 2001, it has been the most fatal air disaster in the United States, and US passenger aircraft has been dropping first in nearly 15 years.
This post can be revealed that the grave expires with one of the most crowded and complex empty patches in the United States and is likely to be liable for misunderstandings.
Following the report of long -standing personnel arrangements between the federal aircraft employees, he worked for two staff members.
According to the transmission of wireless from Wednesday night, the controller warns the chopper that the CRJ-700 passenger jet is too close, and an experienced helicopter pilot was recognized.
However, experts believe that helicopter pilots have been piloted to avoid the wrong plane. This has never seen an American flight until the same model jet aircraft is too late.
Black Hawk Helicopter, which had three crew members and took off near Langley, Virginia, seemed to be clearly expensive when collided with an American Airlines Jet. , Experts said.
However, only 50 feet separates the maximum permissible altitude of the helicopter and the minimum altitude of the specific landing route airplane due to a quarter of the Reagan National. Light said.
The cool audio from the air traffic control was captured at the moment when Flight Safety Agency reported a terrible aerial crash.
“Tower, did you see it?” A Air Control Officer asked and referred to the moment of the shock.
“Crash, crash, crash, this is an alert 3,” he says in the audio.
“Both helicopters and airplanes dropped Crash in the river,” said the third.
The terrible collision is caught by Earthcom sitting on John F. Kennedy Arts for Performing Arts near the end of the river, and heads south to the airport beyond the Lincoln Memorial Hall.
The survey continues, and as the victim's family laments the loss of the loved one, the question is raised how the disaster has occurred.
At a press conference on Thursday's White House, President Donald Trump said the clashes, “it seemed to have been prevented,” and released his democratic preliminary stream.
“In promoting the diversity of FAA, it focuses on hiring people with serious intellectual disabilities and mental disorders. That's surprising,” Trump accurately responsible for tragedy. He said while acknowledging that he did not know the fact.
Among the passengers, there were at least 14 members of the US figure skating team, the world champion skater for a couple from Russia, the four Evari and the Aridia Living Ston family, 11 and 14 years old. 。 All of them have returned from the US figure skate championship held in Wichita on the weekend.
The other was Kia Daggins, a former Kia Daggins, who was looking forward to teaching at the Ward University Raw School in the fall, according to former Pageent director Rally Strong.
Officials stated that there were no survivors, and rescue workers were still pulling out the body from the cold sea of the Potomax river on Thursday.
The National Transportation Safety Board (NTSB) stated that it would be “too early” whether human or mechanical errors were impaired in disaster, but the preliminary report on the case would not be completed for 30 days.
According to the official flight map, one for helicopters for helicopters, which converges near Reagan Airport, has two flight routes for helicopters.
American flights were cleared for landing and on public roads.
Retired Colonel Daralli Gaub, who flew a black hawk helicopter that was involved in the crash, said that there were some factors behind the disaster.
“This is the two major issues I see. I could not comply with the steps established in the airspace around DC, and it was not possible to communicate effectively according to the criteria. did. [air traffic control]He said.
“With some other environmental concerns, they have just created perfect storms.”
One of the complicated factors is the general nature of the air control person's language controller for blackhawk. In a collision video taken from the Kenedi Center, the second jet is seen in the sky, as the flight tied to DC was about to land.
Instead of providing specific information on where the Wichita Airplane is, the controller is an empty “CRJ”, that is, the “CRJ” (airplane type) without showing where the type of airplane is. I asked the military pilot to see.
“The language is usually along the next line.” Do you see the aircraft moving north at 11 o'clock, a little 5 miles? ” I said.
However, the retired Blackhawk pilot said that the generalized language of air traffic controllers may have confused the Blackhawk pilot, which could normally get in the way.

“In my experience, such types of phones and warnings are made very specifically for the clock direction, distance, altitude, and travel routes, so they may have to be seen. No, “he said.
“all [the controllers] 'Look at the aircraft. Can you see the aircraft in front of you? ” [and the helicopter pilot responds,] “Yeah, I will see it,” and that's the end of the conversation -and you are always in a dense environment where aircraft are flying -it is not specific enough to ensure the safe operation of the aircraft. 。
However, former Air Force Pilot and Adam Kingginger (R-Calif) posted on Thursday, simply warn the helicopter of the CRJ approach, saying that air traffic control worked. I insisted.
“When I listen to the audio, [commercial jet] I was participating in the approach [when air traffic control] Was called [the army helicopter, ‘look for the [jet] About approach -that's an aerial traffic control, “said Kinzinger.
However, most experts agree that the ultimate responsibility is on military pilots.
“Why didn't he change direction? Why didn't he even late?” Gaub said.
“Something did not look at the aircraft … so I want to know that they answered why they did not deviate from their flight course at all -speed or altitude “
