Does the wreckage of MH370 lie off Exmouth?

MH370 may either lie off Exmouth, Western Australia or just outside the area already searched,  according to a leading expert monitoring the extraordinary disappearance.

Writing in his MH370 blog, Victor Iannello, a member of the Independent Group – the most respected think tank looking into the disappearance – says there are three possibilities: look along the 7th arc at latitudes north of 25S (near Exmouth in Western Australia); look at previously searched latitudes, but at a greater distance perpendicular to the 7th arc; and possibly re-scanning areas where the debris field might have been missed.

“Now that the recent search effort conducted by Ocean Infinity has ended without finding MH370’s debris field on the seabed, we continue to re-evaluate the evidence and consider other possibilities,” Iannello said in his blog.

“Many researchers that have reconstructed flight paths assume that the aircraft was on autopilot after 19:41. This leads to flight paths that cross the 7th arc at 26S or further south.”

Iannello says that now that the 7th arc has been searched as far north as 25S and at a width of at least +/-22 Nautical Miles, a range of other possibilities need to be considered.

These include the possibility that:

  • There are automated flight paths that end north of the 25S latitude that has not been previously considered;
  • The aircraft was actively piloted after 19:41 and after fuel exhaustion, the aircraft glided without pilot inputs and impacted further from the 7th arc than was searched.
  • After fuel exhaustion, there was an actively controlled glide that ended outside of the areas searched.
  • The debris field was scanned but not detected.
  • The BTO dataset was somehow corrupted, and we are not properly interpreting it.

“Although we cannot completely dismiss any of these possibilities, and each should be further explored, his main article addresses the first in the list, Iannello said.

He noted that Ocean Infinity has expressed an interest in continuing the subsea search for MH370 at some time in the future.

Options included:

  • Scanning along the 7th arc at latitudes north of 25S
  • Scanning along the 7th arc at previously searched latitudes, but at a greater distance perpendicular to the arc
  • Re-scanning areas where the detection of the debris field might have been missed

“Ultimately, the decision where to search must consider other aspects such as end-of-flight dynamics, drift modeling, surface search efforts, and fuel consumption, none of which were considered here,” he said.

“As such, this article is not a recommendation as to where to search next. Rather, this article was meant to provoke discussion about the possibility of an automated flight ending much further north on the 7th arc than was previously considered. Also, the article provides additional data for scenarios in which the pilot intended to land on Cocos Island but did not take the actions required for landing.”

Iannello acknowledged comments received from Mike Exner, Richard Godfrey, and @Andrew in preparation of the article.
