My understanding is that the initial search area in the South Indian Ocean was about the size of Alaska. How long do you think it would take when searching from air and satellite only to find a plane that crashed somewhere in Alaska?
In the case of flight-370, any debris may now be +1,500 miles from the crash site and widely dispersed amongst all manner of other floating trash.
Allegedly aircraft are dropping buoys when debris is sighted and yet nothing is being reported to be picked up by any ship in the search zone. Then they change the search zone entirely so the aircraft don’t have to fly as far. This is just a lot of nonsense to placate certain people. Declare the plane missing forever and be done with this nonsense. It is all theater.
