Did aliens destroy the twin towers?

No, radical Islamic militants backed by Middle-Eastern terrorist organization al-Qaeda hijacked two commercial passenger airliners and intentionally piloted them into the Twin Towers of the Original World Trade Center in New York City, compromising the structural integrity of the towers and resulting in their structural failure, tragically killing thousands of innocent civilians.

When you joke about this event, you metaphorically spit in the faces of the 3,000 families that lost someone that day, not to mention every American with even the slightest sense of patriotism.
