And that is that upon leaving the airspace of Malaysia into Thailand, the pilot changed course to take the plane over the Indian ocean to commit suicide.

It's likely the pilot depressurized the cabin as hypoxia would've rendered the crew and passengers so they were unliikely conscious for any of this. Whether this happened before or after the course change is unknown.

Given the minimal wreckage, it was likely a soft landing in the ocean rather than the pilot succumbing to a medical event. He almost certainly was conscious up until the ocean landing.

The pilot knew the range and likely chose a part of the Indian Ocean that was remote and deep so the wreckage wouldn't be found as the black boxes would reveal this was intentional and it seemed like he intended his family to get the settlement and life insurance.

It's unclear if the pilot was aware of the pinging that has narrowed down the location.

I am curious, did changes take place due to this event ? Like real-time telemetry for airliners where their location is always available and saved on systems not on the plane.

I remember during the search the commentators said that was not done because Airlines did not want spend for that.

I'm sure there has been a lot of thought put into this locking mechanism so that hijackers can't access the cockpit, but how about the rogue pilot scenario like this one? IIRC, pilots outside can enter a code to unlock the door but it can be rejected by the person inside (so it really only applies if they're incapacitated)

EDIT: it appears some airlines mandate at least two people in the cockpit at all times after the 2015 Germanwings incident.
