In a significant breakthrough, investigators have successfully recovered all major debris from the devastating mid-air collision between a plane and helicopter in Washington DC. This crucial milestone marks a major step forward in unraveling the mysteries surrounding the tragic incident, which has left the nation in shock. As experts painstakingly piece together the evidence, families of the victims and the wider public eagerly await answers about what caused this catastrophic event.

All major pieces of the passenger plane and US Army helicopter that collided mid-air in Washington, DC last week have now been recovered, according to safety officials.

Sixty-seven people were killed in the disaster on January 29, which resulted in both aircraft plunging into the Potomac River. The remains of all victims have been recovered, and there were no survivors

Salvage teams are working to recover the wreckage of the American Airlines jet and the Black Hawk helicopter.

The black boxes have been recovered, and crash debris is now located in a hangar in Arlington, Virginia, as the investigation continues.

The National Transportation Safety Board (NTSB) stated, “Investigators will examine the aircraft for witness marks that may provide clues about the angle of collision.”

On Saturday, a plane equipped with lasers flew low over the crash site to scan the bottom of the river. Crews will spend the upcoming days searching for smaller debris and expect to complete their work in approximately one week.

At the time of the disaster, American Airlines Flight 5342 was preparing to land at Ronald Reagan Washington National Airport in Arlington. The flight was carrying 60 passengers and four crew members. Meanwhile, a Sikorsky helicopter, which had three pilots on board, was conducting a training exercise.

Earlier this week, it was revealed that a crucial safety system had been turned off on the helicopter.

Senate Commerce Committee Chairperson Ted Cruz, who has been briefed by investigators, stated that the Black Hawk helicopter had disabled its Automatic Dependent Surveillance-Broadcast (ADS-B) system, which is permitted for military aircraft.

ADS-B is an advanced surveillance technology used to track the location of aircraft. Mr. Cruz mentioned that while the helicopter had a transponder that allowed it to appear on radar, ADS-B provides much more accurate tracking information.

“This was a training mission, so there was no compelling national security reason for ADS-B to be turned off,” Mr Cruz said.

The Federal Aviation Administration (FAA) has begun reviewing airports that experience high volumes of mixed helicopter and airplane traffic. This action follows Mr. Cruz’s request for a safety review.

On Thursday, President Donald Trump attributed the collision to what he called an “obsolete” computer system used by U.S. air traffic controllers, and he pledged to replace it.

He has also connected a diversity initiative at the FAA under previous administrations to the crash.

However, it has been stated that there is no evidence to support the president’s claim.

Last week’s crash was the deadliest aviation disaster in the U.S. since November 12, 2001.
