Having been one of those monday morning quarterbacks, in my defence the 8-18 evacuation timeline was quoted initially by several reliable sources, including the JL official statement. I am very...

Already done above. The high G forces cause the blade tips to rub against the wall, creating friction that suddenly slows the fan rotation, disturbing the airflow, which leads to a compressor stall....

Probably BOTH. Momentary rubbing of the blade tips slowing the fan rotation, the consequent disturbed airflow causes the compressor stall.

Excellent summary, very well phrased. The key to understanding this accident is not so much the direct cause, but the contributing causes, with many lessons to be learned.

It is a genuine door frame, stripped of the slide, internal paneling and opening mechanisms. The locks are bolted in place and in principle should not be able to move. (Of course if any of those...

Can someone confirm if AS actually has an exit door installed, or it is just a fuselage plug ? This door is required to meet certification standards for high density seating, but many airlines with...

I don't think airport closure times are relevant in a disaster relief scenario, even in pedantic Japan.
In any case, the flight time would have been ~30 minutes for a DH3 (275km)

This was my initial thought too based on the engine damage, however if you look at the NHK video frame by frame, clearly the 350 fuselage passes behind (i.e. to the right) of the DH3. The explosion...

In my book that incident amounts to dereliction of duty. With a fuel-fed aircraft fire, if there are any usable exits, you evacuate. No ifs, no buts. There is no guarantee that CFR can contain the...

I'm sure you're right, however looking at the video recordings the strobes were clearly NOT on. A few blips of the ACLs is visible from the camera angle.

Probably just the beginning of the flare. By all indications so far, the likeliest scenario is they never saw what they hit.

Looking at the photo one can clearly see drag marks emanating from the wreckage. Probably the vehicle was part of the cargo and was pulled away during rescue efforts.

What difference does it make that they were AF pilots ? Sad yes, but unfortunately after watching the video anyone with real flying experience will concur with the conclusions of meleagertoo.
