Why do people think that 9/11 was real? Jet fuel can't melt steel beams.?

I assume this is some Truther nonsense. The problem with your question is that while structural steel melts at around 1400°C (2500°F), it begins to lose strength at around 300°C (570°F). At about 550°C (1000°F), steel can lose over half it's strength.

So the steel doesn't have to melt for a building to collapse.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
