If you’re traveling to or through Pittsburgh International Airport on Wednesday, August 26, don’t be too alarmed if you see what looks like an emergency out on the tarmac.

It won’t be a real emergency, but a test of the airport’s emergency plan.

Every three years, the FAA requires the airport to do a full scale training exercise  and to make it as real as can be they use real aircraft, volunteer casualties, and simulated smoke.

Scary, but good to know.
