I remember seeing a bit that he had been using a simulator, but couldn't remember anything being mentioned about what it was used for. Hopefully they can find the black box.
From MH370?
They have to find the aircraft first. They have been searching for over a year, ships by the score, & not a sign of it yet.
Then, if they find it, x,000 metres down in the Indian Ocean, they have to find a way to get it to the surface. It'll be a miracle if the MH370 black box is ever found, & if it is, if it has survived immersion at great pressure for over a year.
Note though, neither of the 2 incidents we are discussing were down to aircraft faults.
