I saw lots of pieces of plane on the ground.
Then when the planes crashed into the twins towers.
When they felt they caused lots of damage to buildings on the side of them.
When a tower felt it splitted a 25 floor the tower splitted in half.
What made the towers fall were the tempeture was melting the irons which made the buildings collasped.
Some witnesses said that it was a normal day.
It was quiet but then they hear a big sound.
They looked up and saw one of the towers with a whole and smoke coming out.
Then 30 mins later the other plane crashed on the other building.
So thats what made the metals to melt because they say the tempeture was a 100o degress.
I saw the towers fall down.
They became pieces of metal tangled.
