The race to find the black box flight recorders is on. This small device, which records flight data and voices from the flight deck crew is the only thing that can truly tell us how and why Air France flight 447 went down on the early morning of June 1.
A French nuclear submarine , the Emeraude, arrived off Brazil on Wednesday, June 10, to begin its hunt for the black box. The Emeraude will begin its first patrol zone this morning, searching an area that’s 20 nautical miles by 20 (37 kilometers by 37). The submarine is expected to cover that much ground in a day, according to military spokesman Captain Christophe Prazuck.
The submarine will change the zone that where it searches for the flight data recorders every day.
It won’t be easy to locate the black box. Even though it is designed to emit signals to aid in locating it, the submarine will have to come close to the box in order to pick up the signal.
To aid in the recovery, the United States has sent two super sensitive listening equipment that may be able to detect the emitted signal at a depth of up to 3.7 miles. These devices are called pinger locators and will be searching for the black box from aboard two French boats.
Once the black box has been located it will be the job of 3 robot mini submarines to recover it from the deep waters.
I really believe that we have the technology to recover the flight data recorders, and I really hope that we do.
There is approximately 20 days left before it stops emitting its location signal.
