We have just heard reports that mutual air companies from Anne Arundel COunty have been dispatched to BWI Thurgood Marshall Airport for an “Alert 2”. According to sources:
ALERT II– is more critical than an Alert I. This Alert indicates that the aircraft is in major difficulty. This could be anything from smoke in the cabin, faulty landing gear, loss of hydraulic pressure, or one engine out on a twin engine aircraft weighing more than 12,500 lbs. The fire department will be deployed to their staging points near the approach end of the landing runway. Operations will conduct a sweep of the runway behind the rescue equipment after the aircraft lands and turn control back over to ATC if appropriate.
No details were provided o the type of aircraft or the nature of the emergency.
