Slow Flight???
No matter what, you gotta give the pilot an A for effort…
Did it lose an engine? Maybe the right engine went out, the loss of power caused a stall and then the rolling to the right because of the left engine still running etc. . . 
look at the exhaust nozzles, they are in different positions…
First thing I noticed when I saw the pics. . .

Not as close in, but shows more of the last moments of flight.
Amazing photos and video footage! 
Glad the pilot made it. If the wind was stronger by a few knots, he’d have been out of the frying pan and into the fire!
At 2:05 into the youtube video, it sounds like the guy says the plane just recently had a $2.9 BILLION upgrade. He MUST be saying Million, but I’d swear he’s saying Billion…
Hell, with a $2.9 billion upgrade, the plane should fix itself!
