Don’t know how factual this is:
Passenger manifest. Several muslim names, it appears.
Yes, there would be; Malaysia is 61% muslim.
What I see is two tech crew had ‘middle eastern/muslim’ names. Also it is not documented but the co pilot had the same and had only been flying 7 years. That is enough time after 9-11 to train a few radical muslim pilots and getting them in the driver’s seat. My thoughts are inside/outside job combo. Probably not the co pilot but tech crew and passengers that had stolen passports.
