Is that really from JFK right now? It looks like complete chaos.
JFK airport is complete chaos in the best of times.
This is actually the thing that worries me--one false alarm, and they make everyone leave the terminal--which is relatively safe--and stand around out on the curb, where there is absolutely NO protection from cars, trucks, etc.
If you think the terminal looks like chaos, you should see what the roads around it look like at this hour.
