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.

“It 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.
