This is a plot by a group of violent fundamentalist Buddhist terrorists.
And since we have no idea who did what, where, why and how, its far to early to judge if it made any sense or not.
That is not to say that I condone senseless violence. However to prevent further incidents you must understand the motivations of the perpetrators and understand from their world view. Just saying they are evil isn't going to help you understand why they did it.
After all if you don't understand how desperate they are, you don't know to what level they will stoop.

If your goal is to acquire a working Boeing 777, on a secret airfield somewhere in Western China or Eastern Kazakhstan (see this map for orientation: http://www.airliners.net/uf/109874/phpnIOEWi.jpeg), then you don't have to be particularly smart or rational to realize that hijacking a commercial flight from Kuala Lumpur to Beijing, with 240 people on board, and then attempting to stealthily cross both India and Pakistan, as proposed in the OP, is not your best option.

- A depressurization event, either as a result of an accident or a botched hijacking (see https://en.wikipedia.org/wiki/Helios_Airways_Flight_522)
- Pilot suicide, with a somewhat unexpected signature (see https://en.wikipedia.org/wiki/EgyptAir_Flight_990)
Pretty much anything is possible, indeed. However, I'd recommend this post on airliners.net for a comprehensive sanity check: http://www.airliners.net/aviation-forums/general_aviation/re...
But: Wikipedia on water landing (ditching) shows a high survival rate http://en.wikipedia.org/wiki/Ditching#Passenger_airplane_wat...
I'm confused.
