The collision of two jets (American Flight 11 and United Flight 175) into the World Trade Center on 11 September 2001 was certainly the most visually horrific (and horrifically visible) part of the attack that day. And it was the part that led to the most deaths, during and after the attack: people in the bulidings, standers-by, police, firefighters …
But …
At the Pentagon, 125 people were killed on the ground, along with 59 victims aboard American Flight 77 when it was crashed into the building.
In Pennsylvania, 40 passengers and crew on United Flight 93 were victims of terrorists as their plane crashed to the ground.
Those places, and those people, were part of the terror attacks that day. And they should not be forgotten.
