In this communication I shall show that only explosives could have produced the large amounts of molten steel found at the site of the World Trade Center (WTC) in the days following 9/11. There is universal agreement by scientists in and out of government that the temperatures reached in the fires were much lower than the melting point of steel. Steel could have only have melted (assuming no explosives were used) if it gained additional energy in falling. I shall show that this gravitational energy is insufficient to cause melting.
Steven E. Jones has made a strong case that some molten steel (or iron-rich metal) was observed pouring from high up in the South Tower (4). In that case gravity was not a factor. However, much more molten steel was probably found in the rubble than was observed pouring out of the buildings, and the purpose of this report is to show that gravity could not have played a significant role in its formation.
Although there are some technical points involved in my arguments, I will describe, in an elementary way, all the scientific concepts involved. This report will also provide references showing that molten steel was indeed found.
