I am going to cut those pilots some slack.
Amazon coming back from Puerto Rico, is going to be near or totally empty of cargo and fuel.
A string off LOADED airliners made successful transits through the weather, and landed = Peer pressure.
The G forces the pilots of the empty plane endured going through the thunderstorm could have been more than twice what the aircrews ahead of them endured
Those passenger plane pilots were PROBABLY more experienced, and better trained in the aircraft they were flying.
The Amazon pilots were probably not aware of the safety interlocks that prevented thrust reverser deployment until landing gear signaled all wheels firmly on the ground.
The lift killing slats have similar safety interlocks, and did not deploy. I suspect that both were selected.
At their speed, and empty, they did not have both gear loaded at the same time until the runway ran out.
From our armchairs, clearly they should have gone around, been vectored to a holding pattern until they could be fitted back in the approach flow. If their pre landing brief included an assessment of fuel remaining, there may have been a strong incentive to get it on the ground, full reverse thrust, slats, and max brakes.
With both reversers and slats selected, they may have feared an even worse outcome if a go around was attempted.
With the “Unstable” approach documented by the ADSB, they were well beaten up, and may have been near wings level most of that time. They would have had an understandable desire to get on the ground.
I have been in a Super Constellation airliner which flew through a violent thunderstorm, and watched the wings flap up and down, when that was the largest airliner flying. When we deplaned, the Captain was not at the traditional location at the door, thanking us for flying with him and his airline (Delta).
If no one died, this would not be such a tough outcome.
