With the available information, i can not help but think they are looking in the wrong location by at least 300 nm or more. If they were in the air for two hours they would be much further north than they are showing.

At 1:30 , 50 minutes into the flight, they already into Vietnam airspace. According to the reports, they fly another 1 hour and 10 minutes, approx 450 nm.

Here’s my conspiracy theory - pilot takes a break, and co-pilot dumps the fuel...causing the fuel slicks that have been found. The deed is done, and nobody can wrestle the controls from him to save the plane. And they just fall out of the sky...but a little north of the fuel slicks.

I had asked the same question earlier, it appears the 2 hr. mark was(if not erroneous altogether)when the aircraft was deemed to actually be missing by the airline.

("when you have eliminated the impossible, whatever remains, however improbable, must be the truth”)

...while actual loss of signal was(+/-)40 min. after T.O.(Flight24 ADS-B plotting)

...at least that's how I interpreted the timeline up till now.
