Most of the lessons learnt from the MH653 disaster were incooperated into MAS SEP procedures wrt to hijack conditions. However most are only applicable in Malaysian airspace as only local ATC and the special actin squad ( UTK ) are familiar with the procedures. It would not be prudent to elabotae further on the specifics in this public forum.
As for the guy you all called scumbag, g-string, etc; I would say unequivocally that he is indeed a real piece of work. Sometime ago to help get a sidekick of his off the hook for a sexual harassment case in MAS, he got his lawyer goons and other scumbags to threaten the poor victim's life. The poor girl ( a fellow Punjabi at that ) had to capitulate and withdaw the complaints. There a lot of nasty things this low life did and I guess those still in MAS should watch out for the son whose is 100% chip of the old nasty block.
