Disaster American Airlines Flight Collides With Blackhawk Helicopter Over DC - Several videos shared online showed footage of the collision and the aftermath of the crash.

An American Airlines passenger plane crashed into the Potomac River after colliding midair with a black hawk helicopter over Ronald Reagan International Airport in Washington, D.C., the Federal Aviation Administration announced Wednesday (January 29) via CNN.

Several videos shared online showed footage of the collision and the aftermath of the crash.



BREAKING: American Airlines Flight 5342 has collided with a UH-60 Black Hawk helicopter near Ronald Reagan Washington National Airport. The military aircraft, identified as PAT25, is believed to be a Priority Air Transport mission, typically designated for VIP transport operations.

From the video of the crash, in my opinion as a lifelong plane enthusiast, doesn't matter how much water there was, the height and speed at which the plane went down is just too much.
I said the same thing a few weeks ago when that Korean 737 skidded into a concrete berm, yet somehow two flight attendants seated in the tail survived. I'm keeping my hopes up that a couple people made it out of the water alive.
 
Are you sure that's not just where the transponder was first picked up? If they don't have ADS-B it might not be as reliable as it normally is.
Not an expert by any means but this seems likely. All the PAT25 flight data comes from MLAT which relies on multiple ground receivers and is less reliable.
 
FYI: the automated collision avoidance system (TCAS) doesn't work at low altitudes.

This is still a collosal fuck up on at least one end.
I don't believe TCAS cuts out until the wheels hit the ground. But it's announcements and warnings are more limited. Its the GPWS that cuts out that far into a configured landing. Because you don't want it screaming "Terrain Pull Up" when you are actually trying to land.
Why was a Blackhawk doing training exercises so close to a commercial airport? And why did it have its GPS transponders turned off?
We don't know yet what the mission profile was. But Government Helo's being vectored at 90 degrees to the runway approach is apparently a regular thing. The Blackhawk was likely on its way home.
Also, why specifically this Blackhawk intended for VIPs and why did a "training flight" depart from Langley?
It may have dropped somebody off. The return flight from Langley to the Base may simply be viewed as "Flight Hours".

MLAT requires multiple ground stations to hear the transponder for a fix so if it's low and in an area without a lot of people running ADS-B/MLAT receivers then it's entirely possible it won't show up.

First fix was at 1000ft, so it could have originally taken off some distance away.

im unsure, likely thats just where it was first picked up. interesting point though, that house is owned by the saudi arabia royal embassy so make of that what you will

Given BWI is a viable alternative, I wonder if they're just gonna try and shut Reagan down since it has only 2 runways, and no room to expand?

The military certainly isn't going to close their fort.

It's also not the most precise or reliable method, even at the absolute best of times.

It's really awesome it works at all given that it's doing passive TDoA on a bunch of iffy-quality receivers with only message-derived clock syncing.

Congress and other powerful people looooOOOOooooove DCA. It's a short Metro run for all of them from their offices to the airport. So despite it being hemmed in and too crowded, it stays.

The Silver Line going out to Dulles takes part of the reason away, but that's still a much longer trip.
