As for the -very popular on Prune - theory of a desperate attempt at a late go-around, the maths don't bear it out :
Estimated landing speed : 148 kts
Estimated speed abeam the camera : 100 kt
Estimated speed at the crash site : less than 40 kt
All point to a continuous, albeit insufficient deceleration, and use of brakes (smoking hot as per one of the initial videos, did they start a fire ?).
Only one board deployed and engine 1 nowhere near full reverse.
