A black box detector deployed by the Haixun 01 picked up the signal at around 25 degrees south latitude and 101 degrees east longtitude. It is yet to be established whether it is related to the missing jet.
Does anyone know what the "...black box detector..." is? Is the Haixun 01 using a towed pinger locator?
From a ULD patent;
Experience during past recovery operations has shown the range of the current conventional ULD design to be approximately one mile.
One mile is about 1600m the depth at 25 S 101 E has been quoted as greater than 4000m so roughly 2500m of cable minimum needed. Specialist equipment surly?
