One person is dead after fire suppression foam was released at a Wilmington Air Park hangar Sunday. Officials say they don't know what triggered the fire suppression foam in the hangar but say it wasn't a fire. One person is dead and 8 firefighters were injured in the response. It all happened around 1:45 p.m. Sunday. As fire and EMS crews were responding, they learned of two people trapped in a vehicle at the entrance of the hangar and one person who was missing. First responders arrived about 10 minutes later but the initial search was cut short due to unsafe conditions. More departments responded and two maydays were sent out. Eight firefighters suffered various injuries from eye injury to electric shock.
