SEARCH crews have relocated signals, hoped to be from MH370’s black box, another two times.

AUSTRALIA – Search coordinator and retired Air Chief Marshal Angus Houston has told reporters in Perth the discovery by Australian ship Ocean is “further encouraging”.

“The detection yesterday afternoon was held for approximately five minutes and 32 seconds,” he said.  “The detection late last night was held for approximately 7 minutes.”
It takes the number of transmissions detected by Ocean Shield to four.
“Yesterday’s signals will assist in better defining a reduced and much more manageable search area on the ocean floor,” the coordinator added.

But he said authorities are not yet at the point of deploying the autonomous underwater vehicle ‘Blue Fin 21’.
“The better Ocean Shield can define the area, the easier it will be for the autonomous underwater vehicle to subsequently search for aircraft wreckage.”
“I believe we are searching in the right area, but we need to visually identify aircraft wreckage before we can confirm with certainty that this is the final resting place of MH370,” he argued.
Australian ship Ocean Shield detected two signals consistent with transmissions from a flight data recorder and a cockpit voice recorder. The first signal continued for two hours, while the second was just 13 minutes.
There have now been four signals detected in total.
Based on Perth time, the first was found on Saturday April 5 at 4.45pm, the second was heard on Saturday April 5 at 9.27pm, the third was detected on Tuesday April 8 at 4.27pm and the fourth was heard on Tuesday April 8 at 10.17pm.  (read more)
