Search suspended for 3 U.S. Marines missing after Osprey crashes off Australia

I dread news like this. My prayers for the troops, their family, friends, and fellow Marines.

how many is that now?

That shouldn't have happen, made in US are the best, side note pray they be found alive and well.

There are lots of reasons for aircraft accidents from design flaws, maintenance errors to errors by the flight crew. Lets let the investigation determine the cause. I pray the three missing sailors are quickly found alive.

I wonder if there try to cover the cause of the accident.

The Osprey is a classic example of a "military intelligence committee" design. Everyone got something. When the US sent many of them to Okinawa, questions were asked because of their range let alone ability to stay in the air. Heads up, everyone, from Okinawa to Hokkaido.
