I asked this question in the previous thread about Dr. Wood, and it is as of yet, unanswered. I thought I would give the proponents of Wood's theory another chance to answer the question, and substantiate her claims. If 80% of the steel from the towers was finely divided into tiny particles of dust capable of floating away, why did we not witness the rapid oxidation of these particles? Given: 1. Steel's mass is mostly comprised of iron. 2. Small particles of iron are pyrophoric. 3. Pyrophoric materials ignite at room temperature when exposed to oxygen. 4. The burning of iron releases large amounts of light and heat. (- 1651 kJ of heat is released for every 4 mol (223.38 grams) of iron burned.) 5. 80% of the steel from the building is tens of thousands of tons of steel Asserted: 1. We did not witness a release of light and heat consistent with the burning of 80% of the iron within the building. 2. A release of heat and light on the order of the entire annual energy use of the Earth would not go unnoticed. Does anyone who subscribes to Wood's theory have an answer for my question?
