@aviation_and_landings: Two planes were flown into the Twin Towers of the World Trade Center in New York City, causing both towers to collapse. A third plane was crashed into the Pentagon, just outside Washington, DC. The fourth plane crashed in rural Pennsylvania after the crew and passengers attacked the terrorists on board, preventing it from hitting another target thought to be the White House. The attacks claimed nearly 3,000 lives. #11september2001 #nyc #worldtradecenter #september11 #wtc
