Security hoax on AA flight - headline writer over dramatizes

Dont call me Shirley said:
"Passengers were evacuated from an American Airlines flight at New York's JFK airport Sunday while police investigate a bomb threat onboard."...
I suspect that most airline people would think "evacuation" means slides.  These people we deplaned via mobile steps on a taxiway. 
Thats would be an emergency evacuation. People tend to get hurt during emergency evacuations.
