I think you may be going overboard with with the top5 airlines. According to SKYTRAX, Malaysia in included in the 5star rated airlines.
I usually stick to any of the airlines that either in the Star or One World Alliance. All of these airlines provide great service and safety standards. Usually I fly Lufthansa or United. Fingers crossed all will be well in the future, the next car accident may be just around the corner....
2013 Top 5 Airlines:
- Emirates - 0 accidents/incidents
- Qatar - 0 accidents/incidents
- Singapore - 2 accidents/incidents
- ANA - 13 accidents/incidents
- Asiana - 4 accidents/incidents
Malaysia is #14 and has 4 accidents/incidents. Air Canada is #19 with 11 accidents/incidents. We don't even get to a US legacy carrier until Delta at #45 (14 accidents/incidents).
If we're talking ICAO compliance, there are only two categories - Category 1 (compliant) and Category 2 (non-compliant).
If you trust Business Insider, Malaysia is #2 in the world behind Singapore.
I don't know what you consider to be Top 5, SRT, but it does seem a bit arbitrary. Accidents and incidents don't discriminate.
(Accident/incident info pulled from Wikipedia.)
As to my personal opinion, I don't think any foul play was involved. I agree with JoDa - emergency coordinates were pre-programmed and executed. We already know the turn was programmed into the computer before the flight went dark. There is also precedent for a 777 cockpit going up in flames very quickly (see EgyptAir Flight 667) and for a plane going through decompression, all crew and passengers dying, and then the plane continuing to fly until out of fuel. (see Payne Stewart's Leerjet). We may not know what happened until (or if) the CVR and FDR are found. We may never know. But I don't see any evidence for the wacky conspiracy theories floating around - alien abduction, terrorists saving the plane for later, pilot suicide, etc. Occam's Razor - simplest explanation is probably the correct one.
