You forgot the crosswind case! Like any aircraft with tail mounted engines, you have a big tendency of yaw forces with reversers on in crosswind. It's obvious that they had very strong crosswind (well, not as strong as in the northern hemisphere, but here with most likely a contaminanted runway). As soon as you revers full, you can get a huge turn movement on the vertical axis. The only solution is to reduce the reversers. So they did several attemps to land, then finally saw the runway, wanted to stop, stop quickly because of the runway condition (after the end there is only sea until India), pulled full reverse and where surprised they got off the runway, blaming the crosswind.

This conclusion follows on from your previous certitude that the airplane landed on RWY 09.
From your profile, I'd guess you were driving for Silkair. Say it ain't so!
I need to maintain my delusion that MI is in a different league from all the other operators into my home port of HKT!
