someone wrote this to me at another forum:
WTC they didnt find much but body parts of passangers, and those where badly burnt. But there is simple math for the WTC.
Planes are mostly made of aluminum. Expect for engines and some of the major structial peices.Humans dont vaporize or cremate until about 2-4 hours @ 2100°F, Aircraft aluminum melts at 1220°F. Jet Fuel burns @ around 1400-1700F, well above aluminum melting point, add in the fact the plane was damn near shreded into little parts upon impact, and it leave you with crispy human parts and melted itty bitty peices of aircraft, then add a entire bulidng mixing in with the peices and you have no plane, and charred crushed body parts left over.
Aluminum takes longer to melt than a kerosene fire would burn. Am I right? Thermate and explosives were necessary for this job.
