Will be interesting to see. If it had crashed into land then I think it might be a real possibility. Into the ocean? I’m doubtful.
Yeh thats really a stretch. More likely that plane is sitting somewhere in a rogue country and the powers that be know exactly where but are stalling for time to figure out what to do about it.
In shallow water- prox 600 feet, and with a speed of 400 MPH, I would think a tremor is possible.
