Hi,
Finding things on the sea bottom is incredibly dificult, especially given the conditions where AF447 crashed. In fact even finding something on the sea's surface is very difficult
But finding something on the sea surface emitting and signaling his position is far more easy.
So it's frustrating that all the (expensives) brains working for the devellopement for a "safest" aviation world had not yet (or want not) design a
reliable device able to float and send his position when a plane crash at sea ...
Remind me .. we .. humans .. were able to go and land on the Moon and return !!! ...
Do we need to revamp the wheel ? .. or it's a "no will" ?
