Все от того же индонезийского источника с airliners.net:
Aircraft was seen on radar at FL363 and 353kts ground speed... later on, mode-S data showed it was at FL240 at -11000fpm and just over 60kts ground speed.
The climb rates of over 6000fpm and even up to 9000fpm were recorded on the Mode-S. Sources also said that at times the aircraft exceeded -24000fpm (yes, 3 zeroes)...
The other thing is that the climb, peak, descend and disintegration/disappearance (ie: FL320 to FL360 over, to FL240 where it disappeared) took just under 1 minute and 10 seconds or so.
Aircraft turned left throughout the drama, except for the end where it tracked east varying plus minus 5 degrees... through the very fast descent rates prior to disappearance.
