Why the Steel structures of the WTC towers dissaperar or evaporated like by magical?
& Why the Main Stream media rejects all Consopiracy Theories that involves Israel? http://wtc.nist.gov/pubs/factsheets/faqs...

Jet fuel burns at 800° to 1500°F, not hot enough to melt steel (2750°F). However, experts agree that for the towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength--and that required exposure to much less heat. "I have never seen melted steel in a building fire," says retired New York deputy fire chief Vincent Dunn, author of The Collapse Of Burning Buildings: A Guide To Fireground Safety. "But I've seen a lot of twisted, warped, bent and sagging steel. What happens is that the steel tries to expand at both ends, but when it can no longer expand, it sags and the surrounding concrete cracks."
"Steel loses about 50 percent of its strength at 1100°F,
What secret material was used in the demolition?

Thank you for answering my question.
My problem is that I have a Logic IC that it's name and IC number is fully cleaned & I did'nt know any think about it.
By analysing the circuit that this IC used in it, I had determined its VCC & GND but I need to determine it fully.
I want only a way for determinig its pin (input or output).
Then I can find its truth table for every output by letting different input valuations to it and processing its response by an AVR.

Can you help me?
please place your mail here or mail me your answer if you want, then I can explain you more details of problem and ...
