While there are countless facts still left to be uncovered and scrutinized, there's an early indication that the worst US air disaster since 9/11 may have resulted from a flight-path deviation by the Army helicopter that collided with a passenger jet landing at Washington's Reagan National Airport. Remarkably, it appears an identical disaster may have been narrowly avoided just one day earlier, when an airline pilot chose to abort landing after deeming another helicopter was dangerously close. Control-tower staffing is also emerging as a major concern -- including a decision to allow one controller to leave work early. 

Based on a determination of the UH-60 Black Hawk helicopter's last location before colliding with American Airlines 5342 from Wichita, the Army chopper was flying above its authorized flight path, according to anonymous sources who spoke to the New York Times. The American CRJ300 stopped transmitting tracking data at 375 feet -- suggesting impact occurred far above the 200-foot ceiling imposed on helicopters in that area. 

The Black Hawk was reportedly under the command of a female pilot with more than 500 hours of flight time. The male instructor pilot had more than 1,000 hours, while the crew chief is also said to have logged hundreds of hours. Given the shorter duration of helicopter flights, those hours are substantial, according to Jonathan Koziol, a retired Army chopper pilot who's assigned to the Unified Command Post that's been organized to coordinate the post-disaster efforts at the airport.

The Army has not released the names of the crew members, but the names of the two males aboard the Black Hawk have emerged via other channels: Staff Sgt. Ryan O'Hara and Chief Warrant Officer 2 Andrew Eaves. All were assigned to Bravo Company, 12th Combat Aviation Battalion, headquartered at nearby Fort Belvoir.

While there are many social media posts purporting to identify the female pilot as a male-to-female trans National Guard member who on Tuesday publicized his transition, ZeroHedge cannot find authoritative confirmation of those claims as this article is being written. On Monday, President Trump issued an executive order barring transgender people from openly serving in the military. Update: The trans pilot in question, Jo Ellis, has released a video confirming he is still alive and was not piloting the Black Hawk. 

The Army says the crew was conducting a routine nighttime qualification flight, with the focus on safely navigating helicopter routes in and around Washington. However, more specifically, Secretary of Defense Pete Hegseth said the crew was training for a "continuity of government mission." That's the name given for a response to an attack on the capital, or a major disaster that hits the city. In such an event, helicopters would be used to evacuate senior federal officials. The crashed helicopter was a standard UH-60; the battalion also flies the VH-60M variant: Distinguished by its gold top, it's used for VIP transport.
