5. The Thai got a RA to climb but seem not to follow it . ( or only climbed 126 ft in 15 seconds )
Well, you'd expect their RA to soften, and with the other aircrafts large overreaction it would soften earlier.

Haven't got the tables in front of me, but IIRC TCAS is shooting for a miss of about 700 feet at that altitude. By the time they had started to pitch up, the other aircrafts predicted separation at CPA was probably increasing rapidly through 700', thereby allowing their RA to soften.
