In answer to the Sobelena post you replied:
I think you failed to grasp Sobelena's point
Well OK, you tell us - short of an FDR/radar/ADS-B trajectory plot, what would you consider as indisputable evidence of either the undershoot or overshoot scenario ?
Have you seen any such evidence yet ?

I suggest that it is likely that the journalist asked: “Do you think you should be rewarded the bravery you displayed at that time in utilising your skills to save lives”
And he replied '...sure...'.
Journalists love to put their own ideas and preconceptions into the words of their interviewees.

Well feel free to correct me if I'm wrong, but he/she appeared to be remarking on the fact that,10 days on from the accident, there doesn't seem to be universal agreement on the circumstances:
I simply pointed out that the evidence that's going to resolve that unambiguously (FDR traces, for example) hasn't yet been published.
What do you think he/she meant, and how would you have responded ? You still have time.

Press release today from the FSM IIC, which explains the continuing delay in downloading the FDR and CVR:
Press Release by the FSM Investigator-in-Charge / October 10, 2018 at 6:00 PM / No. 7
The aircraft accident investigators from the FSM, PNG and the USA arrived in Port Moresby from Chuuk on Sunday 7 October and immediately commenced work preparing the recorders for data download and subsequent analysis and analyzing records.
PNG AIC is using state of the art download electronic equipment specially brought to PNG from Canada for this accident investigation.
Because the aircraft crashed into the Chuuk Lagoon the recorders had been immersed in salt water. The AIC investigators have today completed the disassembly of the recorders to remove the data memory chip boards while they remain immersed in water. They have painstakingly cleaned them in distilled water to ensure no salt water and other contaminants remain on the boards.
The FDR and CVR boards are being dried in an oven for between 18 and 36 hours to ensure all traces of moisture have been removed before being connected to the downloading electronic equipment.
The international teams from PNG and the USA have been diligently assisting the FSM investigators. The Government of the Federated States of Micronesia is grateful for their support to achieve the best possible safety outcome for aviation globally and particularly in our region.
The FSM Government is pleased to learn that the PNG AIC is buying the 21st century technology MARS recorder download and analysis system and the Insight Flight Animation Software. This will ensure the AIC is at the cutting edge of this technology and will be equipped to conduct flight recorder downloading and analysis for years to come. This is vitally important for aviation safety throughout Pacific Region.
Official update to the media will be issued by the FSM Investigator in-charge.

Further press release yesterday, 12th October:
Press Release by the FSM Investigator-in-Charge / October 12, 2018 at 6:00 PM / No. 8
On Wednesday October 10, 2018 investigators from the PNG Accident Investigation Commission (AIC) successfully downloaded the data from the Flight Data Recorder from the Boeing 737 that crashed in Chuuk lagoon of September 28, 2018. This was followed on Thursday October 11 with the successful download of the data from the Cockpit Voice Recorder.
The meticulous preparation and cleaning and drying of the data chip boards by the AIC investigators and the use of the state of the art MARS recorder download and analysis system brought in from Canada, was instrumental to the success of the downloads, and speeded up what would otherwise have been a much longer process. This process was conducted in the AIC’s Flight Recorder Laboratory in Port Moresby in the presence of an investigator from the FSM.
The data will now be jointly analysed by the FSM TC&I investigators and investigation teams from the US NTSB and the PNG AIC to determine the factors that contributed to this accident.
The AIC will analyze the data using the latest version of the Insight Analysis software and the Flight Animation System (FAS). This will provide the FSM Investigation team with a high quality animated visual reproduction of the recovered data.
Our respective Nations’ resources are finite, so it is important that small countries such as PNG and FSM share resources and draw on available expertise in the interest of aviation safety improvement. The people of FSM and PNG are assured that their safety is paramount whether they are travelling in FSM, PNG, or flying beyond our borders.

Regardless of water damage, the data is recoverable.
My evidence is anecdotal, but I have recovered "water resistant" equipment soaked in 50-100 ft salt water before.
When I was a radio technician I restored many Motorola radios (surface mount, close spacing between traces, pre-MIL-STD-810C) to service after being immersed in salt water for weeks before the divers got around to harvesting them. I had a 100% recovery rate by flushing them and soaking them in distilled water, followed by a flush/soak of about 10% isopropanol and an low-temp oven bake. (They usually became corroded and unreliable after a year or so).
In this case, a rinse and bake after a week or two if immersion will certainly allow for full data recovery in short time.

Micronesia is a “United States associated state”. Why is the NTSB not investigating this accident?

country of accident
country with most passengers/citizens involved
issues relating to operation, Weather, ATC, Airport, pilot training etc.
issues relating to airworthiness of aircraft or engines
Availability of pertinent facts or investigating expertise including manpower

We know, for example, that the FDR and CVR have gone to PNG for analysis (overseen by FSM investigators), whereas the EGPWS has gone to the manufacturer in the USA.
Regardless of who is carrying out various parts of the investigation, the protocol is that the lead state (FSM) is responsible for release of any information on its progress. That, so far, has taken the form of 8 press releases at the last count, plus an undertaking to publish the usual interim report within the prescribed 30 days.

Thanks.
It makes sense that what is normally "waterproof" may not be waterproof after an abnormal event, which event is the reason for accessing the data.
However, this event appears to have been relatively gentle, hence my (ignorant) surprise.
