Knowledge ?
20 people on that flight worked for one company.
Seriously? Let’s say the plane safely landed somewhere. Let’s say the passengers were offloaded, slaughtered and buried.... Or put on ice until they cann be used as hostages. Let’s then say the plane spent the next several weeks being repainted, refitted with bombs or whatever.
Now the plane, after being in hiding for however long needs a nice long runway to take off from, with every friendly intelligence agency throughout the world figuring out which airports can have a 777 take off from it.
So now the plane takes off. Where is it going? Because if it is going to the west it will have to fly under the radar for a couple of thousand miles. With qualified pilots who are trained 777 flight operations doing it. Let’s assume that both the pilot and co-pilot were in on it.
Sorry, not buying this. I am more apt to think that the Chicoms fried the planes electronics from space and the pilots in their confusion tried to turn the jet around and nose dived into the sea.
