I was a freshman in high school. On our way to school, the bus driver had the radio on and they mentioned a plane hitting one of the towers. No one had any details. I remember them saying they (DJ’s) thought it was a small prop plane.
Exactly the same experience for me too, on the radio they thought it was a small plane and seemed to downplay it. When I got to school and saw the TVs, I knew it was a much larger deal than what the radio was saying. The rest of the morning we were all glued to the TV and remember the gasps of watching the 2nd plane hit live on TV and then the towers falling, everyone sitting in shock.
