I am fine. I fly the A320 for Spring Airlines. I am currently locked down in my apartment complex with everyone else getting covid tested.



Just glad you're good to go.

A news helicopter took this shot of the impact crater. The entire plane disintegrated to millions of small aluminum pieces.

When I first entered USAF pilot training they had us take foot prints. Very much like finger prints, you step on an ink pad and then step on a piece of paper. Why? Because if you crater in like the above picture your feet are the only thing that might survive intact for identification.

And if you wonder why they haven't found any wreckage on the bottom of the ocean from the lost Malaysian Airlines flight 370 it's most likely because it disintegrated upon impact. Hitting water at high speed is not soft.

I'm happy that you are okay.
Although I'm not a flier by any stretch of the imagination, I understand what you are talking about. Same as with a lot of industries. Sad, though.

Reminds me of when my wife visited NASA, as part of a work/study group, years ago.
They were viewing the bay/hangar where the shuttle was being reworked.
When they entered the room, they were required to remove their "Visitor IDs", and place them in a rack, outside the room.
That was because, if there was "an accident", they would know who/how many people had been in the room, when it happened.

Glad to here you are fine. Watching the crash made me cringe.

There is a ton of speculation currently about the crash. The video I've seen shows an aircraft coming out of the clouds in a vertical dive. There is no official word from my company yet.

I hope it's not what I and others have been complaining about. That is the lack of actual flying skills. We are taught to always use the autopilot. Now when the aircraft is so broken the autopilot doesn't work then you better have the skills needed. Most do not. We shall see.

This was a Boeing 737-800 I believe. With everything going on don't be surprised if China pivots to Airbus even more. Plus they have an airplane under development here to rival both the 737 and A320, called the C-919. It's a mix between the two previous aircraft.



could the pilot have thought the ac was stalling and pushed the nose down and just wasn't able to recover?

News release from the NTSB...

The National Transportation Safety Board determined during a public board meeting held Tuesday that Atlas Air flight 3591 crashed in Trinity Bay, Texas, because of the first officer’s inappropriate response to an inadvertent activation of the airplane’s go-around mode, resulting in his spatial disorientation that led him to place the airplane in a steep descent from which the crew did not recover.

The NTSB concluded the first officer likely experienced a pitch-up somatogravic illusion – a specific kind of spatial disorientation in which forward acceleration is misinterpreted as the airplane pitching up – as the airplane accelerated due to the inadvertent activation of the go-around mode, which prompted the first officer to push forward on the elevator control column. The first officer subsequently believed the airplane was stalling and continued to push the control column forward, exacerbating the airplane’s dive. However, no cues consistent with an aerodynamic stall —such as stick shaker activation, stall warning annunciations, nose-high pitch indications or low airspeed indications—were present. Additionally, the NTSB’s airplane performance study found the airplane’s airspeed and angle of attack were not consistent with having been at or near a nose-high stalled condition. The first officer’s response was contrary to standard procedures and training for responding to a stall. The NTSB concluded that while the captain, as the pilot monitoring, was setting up the approach to Houston and communicating with air traffic control, his attention was diverted from monitoring the airplane’s state and verifying that the flight was proceeding as planned.

LOOKS like a catastrophic structural failure. How it got to that condition is anybody's guess.

The video posted earlier looks different from the above posted photo.

There is a ton of fake stuff being posted. Mem, you know that's not how airplanes work. If the tail just suddenly detaches the aircraft does not act like a missile, it acts like a frisbee. Look at the American Airlines crash in Jamaica, NY when the FO was kicking the rudder so hard it broke the vertical stab. Now if an aircraft is accelerated enough the tail might detach AFTER reaching the critical mach number, but not before.

There was a crash in South America of an older 737 where one of the two gyros had failed and was giving erroneous attitude information. In this case you are supposed to compare the two attitude indicators to the standby attitude indicator to figure out the bad one. Not sure why they failed to do this but the aircraft was flown out of control and disintegrated midair from a high speed dive. They found the airspeed indicator in the wreckage stuck at something like 505 knots.

At cruise altitude it's not likely this exact thing occurred. But it very much could be spatial disorientation from other things. I don't know if I have ever told ya'll about the peculiar things the locals do here. When they get to cruise altitude they place newspapers or maps or whatever over the windscreens to keep out the sunlight. Most of the time it's only where the sun is directly shining onto a person but I have seen the entire cockpit papered over. Something about the ink on the paper blocking the radiation from the sun.

There are many plausible reasons a flyable aircraft was flown into the ground. Pilot error from not following the checklist or flight manual, terrorism, suicide by pilot, mechanical failure. Normally aircraft don't just fall out of the sky at cruise. The 737-800 has been flown many years without issue. And the possibility exists you will never know what actually happened because it makes the locals look bad (i.e. lose face). Forget all the death and destruction, you cannot lose face to the world. That's most important.
