	Here's an odd theory to go with your odd observation.  

	lightning, mysterious red & blue bolts discussed in the NYTimes.
	hafnium carbide (see below).

	one very nasty transition, resulting in an explosion in the 
engine, which reached a critical state as the sun's rays struck through 
the clouds.  The hydraulics in the rudder did not cause the plane to 
roll; it was the torque of the explosion.

	Of course what do I know about the wreckage, the conditions 
during the crisis, the angle of the sunlight into the turbines...

	Find me the hafnium, & you'll know what happened to the "... engines
and people and chairs and wheels."

Hmmmm...  pure Hafnium?

Hafnium is more important in the form of a carbide.  These materials
are potential candidates for scram-jet engine components and rocket
nozzels.  The way in which the carbon is introduced to the reaction
to form Hafnium carbide can also serve to increase the porosity (i.e.
lower the desity) making for a more aerospace quality material.

I think that the Russians were were playing with Hafnium carbides at
the turn of the century... this is not a "new" material...
