Advanced black box finder deployed to missing MH370 search zone
The hunt for missing Malaysia Airlines flight MH370 is growing ever more complicated. High-tech search tools, including hyper-sensitive towed pinger locators, autonomous underwater vehicles, and remotely operated vehicles, appear to be the best means of tracking down wreckage from the Malaysian Boeing 777.
Once a search zone is identified, the TPL 25, a towed pinger locator, will be lowered into the water and pulled behind a ship. When a signal from the jet’s black box is detected, an acoustic pulse is transmitted up the tow cable, and presented audibly via an oscilloscope or headphones.
The operation is repeated until the location of blackbox is approximated via triangulation.
Once the location is confirmed, the Bluefin 21, a robotic mini-submarine, will be deployed. Sonar pulses sweep in two arcs and show acoustic reflections of objects on the seafloor.
After the visual data of the crash site is obtained, the Remora 6000, a remotely operated vehicle will be sent to collect materials from the site.
The search area for the missing plane was narrowed down on Tuesday after two more pings were heard. The head of the multinational search effort, retired Australian Air Chief Marshal Angus Houston told reporters that he was optimistic the jet would soon be found.
