I’m hoping that China has an interest in not covering up this incident. Despite being a habitual liar (like MSNBC!), China may want the truth to come out here.
How about 2 Iranians with fake passports coerce the co-pilot into killing the pilot and taking the plane. Instead of the co-pilot takinheck troll of the plane, he is killed also and now you have 2 Iranians with no experience flying a plane at 600MPH. Last thing the co-pilot does before he dies is take the plane off autopilot.
No flying experience, no radio experience the plane stays aloft for as long as possible before it the terrorists pull back the stick. It stalls and nose dives into the ocean.
Plane is off course, no debris and under a few hundred feet of water.
