It seems like results for Hubei province are different from those for the rest of the world. If we assume that the time to recovery is similar to the time to death, we can get an idea of the death...

Ignoring the very left hand side of the graph, it looks to me like neither AoA indicator reads zero until the airspeed increases. This isn't surprising - without airspeed, we'd not expect them to...

I'm not convinced by the 26th bit error theory. If you look at the AoA data from the previous flight in Fig 7 on page 16 of the preliminary report, the AoA disagreement is there from the start, but...

Sounds to me like what is known in computing circles as an "integer overflow". If you use a 16-bit integer to store altitude, you can only store values between 0 and 65535. After that it wraps back...

Even right after the fire, it doesn't look like the damage was very visible from the starboard side:

I'm not a professional pilot either, but it seems to me that if you have a potential fire at the front of the aircraft and you have a choice, you wouldn't want to evacuate facing into the wind.

From the pictures, the flames on the ground are in Wandsworth Road, about 200m due south of the crane. So this does sound plausible.

My understanding is that the liquid nitrogen is just for the ground tests of the heat exchanger. An actual engine would use the liquid hydrogen fuel for this purpose.

BusyB,

Odd, the link works for me. Or just Google for "AAIB Report No: 8/1977."

Certainly a gutsy decision to turn off the runway when it became clear they weren't going to stop in time.

It occurs to me that differential heating might play a role in such a failure. This is purely speculation - I have no experience of aero engine design, nor any inside knowledge.

What will matter is where the vertical stabilizer was found. If it is close to other wreckage, I would think it is likely it was still attached for most of the descent. Can't read too much into...
