Assuming this latest find is also from MH370, hard to imagine both bits ascended
from 15,000` or so depths. More likely these separated on impact with water. On such a premise there must be other debris afloat. What are the chances that just these two bits came off and the rest went down all in one piece. Perhaps time to call it a day, get heads out of the water, stick specs back on and start using eyeball MK1.
