NORTHEAST PHILADELPHIA - December 8, 2007 --"Don't hit button unless in an emergency" ... well, one curious kid just couldn't resist the warning. Today was family day at Agusta Aerospace, located at 3050 Red Lion Road in Northeast Philadelphia. Employees and their families gathered for a day of fun in a helicopter hangar this morning. Everything was relatively normal about the event until shortly before 11 a.m.. That's when authorities say an employee's child hit a button that said "don't hit button unless in an emergency". The button triggered the fire suppression system, filling the hangar with foam. The Philadelphia Fire Department was called out to the Northeast Airport to clean up the scene. There were helicopters inside of the hangar at the time of the incident. At this point there's no word on any damage to the helicopter.
