Key chemical reaction may have felled Twin Towers

EXPLOSIONS triggered by molten aircraft metal reacting with water from sprinkler systems may have felled the Twin Towers after the 9/11 attacks, according to a new theory.

Just before the two World Trade Center skyscrapers in New York collapsed on 11 September 2001, powerful blasts were heard within the buildings.

A leading materials scientist says they could be the key to the dramatic conclusion of the terrorist attacks.

Over-heated steel beams have been blamed for the towers suddenly crashing to the ground after they were hit by two passenger jets.

But Norwegian expert Dr Christian Simensen believes explosions caused by a chemical reaction between molten aluminium from the aircraft and water ripped out the buildings’ internal structure.

“Both scientific experiments and 250 reported disasters suffered by the aluminium industry have shown that the combination of molten aluminium and water releases enormous explosions,” said Dr Simensen, from the Sintef institute based in Trondheim, Norway.

Around 3,000 people died after the jets hit the towers.
