Bourse - French Submarines To Resume Search For Brazil Flight Boxes
Quote: "Starting next week, French submarines will attempt to track down the devices, in a second search phase lasting around a month, said a statement from the French bureau leading the crash investigation, the BEA."
I wonder why only a month?
In Johan Strumpfer's account of the search for the SA 747 in 1987, it was estimated that the total area of search would have stretched in excess of 800 square kilometres, an area that would have required in excess of six months. Ocean depth was in places over 5 km deep and very mountainous.
