principles. but most airlines have dramatically improved their reporting, the so-called en route reporting for this. and it's worth mentioning here, it is worth mentioning, i do not foresee that we would be in a similar situation that we are in 370. for several reasons. firstly, there's more reporting from the computers on board. but also the air space around here. we are not talking about the deep indian ocean here. we are talking about congested air space around southeast asia. so there will be much better radar coverage. there's certainly much better air traffic control coverage of it. and even if the plane were between radar centers, there will be much better information on where this plane -- where it was at the time. that i'm pretty certain about.
