NORTH HAMPTON, N.H. (AP) – A man and woman from Massachusetts were seriously injured Monday evening when their single-engine plane veered off a runway and slammed into a hanger during takeoff.

Authorities say the plane was departing from a grass runway at Hampton Airfield just after 6 p.m. when it suddenly shifted to the right and one of its wings clipped the hanger, spinning the plane nose-first into the building.

β€œIt hit with such force that the engine and prop are in the building,” said North Hampton police Lt. John Scippa.

Officials did not identify the people on the plane, a Cessna 170B, but said they were being flown to a Boston hospital.
