OK - given all that -- you are left with only one conclusion (or at least I 
am) -- progressive structural failure, the loss of support where the plane 
hit was sufficient to put excessive stress on the remaining structural 
members, resulting in a catastrophic sequential failure -- it doesnt take 
exotic chemical mixes to put excessive mechanical stress on a system... just 
chop out enough supports.. it may take time for the remaining supports to 
deform enough to reach the failure point.. but they will get there, as 
demonstrated -- occams razor dude -- the least hypothesis is usually the 
right one -- and I get enough conspiracy theory crap out of my dad -- makes 
a good movie -- but doesnt pan out in real life -- too many whistle-blowers 
around !!

The city I live in is installing those red-light cameras to catch 
light-runners -- my dad likes to claim that they manipulate the yellow time 
to catch people in the intersection and increase revenue from traffic 
tickets -- I told him to shut up until he got out there with a stop watch 
and proved it -- and I say the same to you -- PROVE it -- then make some 
noise -- conjecture and conspiracy theories without proof are a waste of 
everyones time. -- how do you know the sulphur was in large quantities ?? 
did you do a chemical analysis ?? or can you produce one done by a reputable 
metalurgy company ??

Ohhh and by the way -- high sulphur steels are regularly used for machined 
components -- was the amount of sulphur detected incosistent with what may 
have been present due to the use of high sulphur steels ?? (where is that 
metalurgy report again ??)
