I find it sad with todays technology that the control centres along the route had no idea what was going on. I'm glad that I now operate in areas of good communication & radar coverage. There is no excuse......apart from penny pinching.

Do you really think the US *only* used satellites to "help" discover the crash site? That's no different to flying high over the area and using a pair of binoculars.
