Is the Science Legit? Thanks for stopping by! Colin Campbell, this should seal the deal. Proud meat-eaters are less enthused, sometimes hilariously so.
Recent Activity Seabed Constructor, the vessel operated by Ocean Infinity to scan the seabed in search of MH, is returning to port in Fremantle, Western Australia, to refuel, change crews, and resupply.
Constructor is completing the second of three or four swings, each swing lasting about six weeks. After that, the extended search area along the 7th arc would require scanning about 46, sq km to reach north to around 29S latitude if the width of the search was 25 NM on either side of the 7th arc.
That will require more than one additional swing to complete. In fact, it could prove challenging to complete with even two additional swings, depending on the weather and how well the eight autonomous underwater vehicles AUVs perform.
Although not publicly stated, there are indications are that at least one of the AUVs is having technical problems. So we can be fairly certain that the large, blurry objects seen in the French satellite images were not from MH, as the corresponding impact locations calculated by CSIRO were searched without success.
Also searched was the warm spot that was calculated by assuming that the aircraft flew until fuel exhaustion on a path towards the South Pole. Unless an interesting contact was found but not yet disclosed, this scenario also can be dismissed.
In the coming weeks, other scenarios will be searched, including the impact site near 30S latitude that is based on two floating debris fields that were spotted during the aerial surveillance, and discussed at length in a previous post.
A descent at The last radar target was captured at There is simply no way to be sure of the path of the plane during this interval.
A similar shift, but in the opposite direction up might have occurred due to the inflight power cycling. Pilot inputs after The continuous, smooth progression of the BTO and BFO data suggests automated flight with few or no pilot inputs until fuel exhaustion.
However, there is a remote possibility that the smooth progression of values was produced by a more complicated path that by chance replicated the simplest of paths. The final two BFO values indicate a steep, increasing descent that if continued would mean the plane impacted close to the 7th arc.
The debris is also consistent with a high-energy impact. However, it is possible, albeit unlikely, that a skilled pilot carefully recovered from the high-speed descent, regained altitude, and glided for some distance beyond 25 NM.
Although some of the area north of the priority search area was searched by aerial surveillance in the weeks following the disappearance, the search area was large and the coverage was spread thin.
Also, some debris was seen from air, but never recovered due to the distance of ships supporting the search effort. Richard is quite talented at extracting a lot of information from small amounts of data, and this video, like all his work, is commendable.

Those of us with experience in the field have known about retrace error since the beginning. It has not been discussed much because it is very difficult to estimate separately from all the other possible small OCXO offset errors. Given what is known now null areas south of S32it is likely that the BFO bias did change slightly after the Together, these errors in post If we assume a combination of retrace and drift error, the lowest BFO errors may be found for paths ending in this northern part of the arc.
It must be emphasized that there is no evidence to support a specific post But the more area searched to the SW, without a find, the more likely it is that there was a bias change.
