I was locked down in hs on 9/11. Huge ass schol across the interstate from a gigantic airport, one of the busiest/most iconic in the nation.
They kept us locked in, as well as gated with the Deans roaming campus. No one in or out till school let out that day and some teachers even tried to TEACH us as the planes were landing flying just over the roof which obv freaked us out.
Parents should always be able to pick their kids up.
