DERRY — Two teenagers were seriously injured in a single-car accident just after 10:30 last night on Gulf Road at Hampshire Drive.
Emergency personnel found two seriously injured teens at the scene — the 17-year-old male driver with life-threatening injuries and a 16-year-old female in the back seat, also with life-threatening injuries.
A third teenager, a 17-year-old male, was walking around and had minor injuries.
The other two teens were trapped inside the mangled car, which fire officials said struck a tree at high speed. The teen who escaped serious injury had been wearing a seat belt, according to fire officials.
All 15 on-duty Derry firefighters responded to the scene. Medical helicopters were called in from DHART and Boston Medflight.
Rescue personnel used hydraulic equipment to free the trapped and seriously injured teens. Extrication was completed in less than 10 minutes.
Once freed, each patient was moved to an ambulance. There, three firefighter-paramedics and two firefighter-EMTs were assigned to each teenager.
Crews performed "multiple, life-saving, advanced life support procedures on each patient while preparing them for air-transport," according to Battalion Chief Jack Webb.
Derry police and Salem Fire Department closed the intersection of Island Pond Road and Route 111 for a helicopter landing zone.
The male driver was taken to that landing zone and flown to Massachusetts General Hospital by DHART. The female patient was taken by ambulance to the landing zone at Parkland Medical Center, then flown by Boston Medflight to Tufts-New England Medical Center.
The third teenager was transported to Parkland for treatment.
The scene was deemed under control at 11:07 p.m., Webb said.
The accident is under investigation by the Derry Police Department.
Londonderry firefighters provided station coverage and off-duty Derry firefighters were recalled to their stations.
Webb said the accident occurred when there were two Derry fire dispatchers on duty, which "allowed for rapid and efficient resource management and greatly improved scene coordination."
