A couple remarkable things about this:
1) Nobody on the ground was killed in part because the ATR twin turboprop went down nearly vertically into a yard that must have been unoccupied. It looks like there was some structural damage, but not a lot.
2) It's being reported that multiple people who were supposed to be on the flight missed it because they were at the wrong gate.
RIP to the 57 passengers and 4 crew.
