Very strange situation with this missing flight. I personally don't think it was a terrorist act as there are more likely scenarios for having a fake/stolen passport than terroristic reasons. I think this plane went straight into the water and we'll find it soon, but with such little information all options must remain open.
Agreed.
With ruling out conspiracy theories, we pretty much only have the following:
An oil slick in the S. China Sea.
An abrupt turn from 020 to 330 before losing contact.
No indication of rapid descent that we know of.
So in ruling out terrorism (which should be the first thing to be ruled out, but isn't thanks to people jumping straight to a 9/11 or Maldives or similar situation), that leaves the following possible parallels.
SWR111. perhaps something mechanical that caused a problem, they tried to turn around, but was too late. However, no Pan or Mayday call went out, nor did they squawk 7700.
CAL611. Inflight breakup, as previously mentioned.
AFR447. Not likely, as weather was clear.
TWA800. Again, not likely.
What we are missing is that if this was as close to VVTS airspace as it was WMKK airspace,
there should have been a drop of target and a handoff between WMKK and VVTS ATC. The LiveATC feed covers aircraft leaving WMKK and heading to the northwest, so we won't know if this happened until the tapes are pulled in Kuala Lumpur.
Before jumping to anything related to the B772, there weren't any ADs that came out recently requiring maintenance for this aircraft. 9M-MRO did have that maintenance done due to a collision on the ground, but that was roughly it. This bird was 12 years old.
So right now, nothing is known, so before jumping to anything, we wait to see what has happened.
