MH370 – Who did it?

15 days after the disappearance of MH370, everything is a blank. There is not a single trace of its where about. While the family members are griefing and in a state of desperation, the experts are still searching for an answer. Assuming that it is indeed a hijack, it can be expected that it is a professional job executed by a fairly big team of hijackers. With this as a basis, let me ask a few questions that hopefully could narrow down the list of suspects to a few possibles.

1. Who have access to the cargo bay of MH370?
2. Who have access to the ground crews loading the aircraft? These two items assume that there are many hijackers and weapons to be loaded into the plane. Remember the mangosteens and durians in the cargo manifest?
3. Who would be able to get the ground crews to work for them?
4. Who would know the flight plans and details of MH370?
5. Who would know the radar locations and their performance specifications including the air traffic procedures and location to handover from KLIA to HCM City?
6. Who could file imitation flight plans without being detected or cause suspicion. This would allow the aircraft to switch transponders and fly as another legitimate aircraft in the commercial corridors after it disappeared and reappeared. All flight plans of aircraft transiting through the spot MH370 was last seen at about the same time need to be investigated.
7. Who had the technical knowledge of the aircraft instruments?
8. Who had the knowledge to fly the aircraft to avoid radars?
9. Who could prevent the pilot and co pilot from transmitting emergency calls?
10. Who had the ability to silence 239 hostages from making a single call out?
11. Who would have access to remote airfields within the range of MH370 and could land stealthily and without arousing suspicion?
12. Who could secure the aircraft and passengers in a large and safe place undetected?
13. Who have the resources to keep 239 hostages alive and unseen?
14. Who knew the topography of the Antarctic Ocean and where to dump the aircraft and black boxes and with very slim chances of recovery?
15. Who had the facilities to refuel the aircraft and fly it to the Antarctics?
16. Who had the presence of mind or informed knowledge to search in such far off and remote area that was unreachable by MH370 without refuelling?
17. Who could bring the pilot and crews back to safety from the Antarctics after dumping the plane? Items 14 to 17 assume that the aircraft is dumped in the Antartics?
18. Who would have a reason to want to attack a Malaysian aircraft with mainly Chinese passengers?
19. Who had the logistics to hold the hostages for so long without making a demand?
20. Who could do all the above and successfully complete this hijack mission and keeping the whole world in the dark?

The answers to the above questions could point to a few possible suspects with such capabilities, knowhow and resources to pull it off. The whole exercise is a logistic nightmare.
