An air ambulance was scrambled to deal with a collision on the A14 near Thrapston on Sunday afternoon (January 11).
The Magpas Helimedix, based in Huntingdon, was caled to the scene after a collision involving three cars shortly before 1pm.
The helicopter landed on the carriageway near Keyston and the team, Dr Nick Foster and paramedic Simon Standen, assessed a woman in her 40s who suffered head injuries.
A spokesman for Magpas said: “The Helimedix treated the patient, before she was taken to Kettering Hospital, in a stable condition, by land ambulance.
“Two paramedic crews and an EMAS Ambulance Service Rapid Response Paramedic also assessed a small number of other patients at the scene.
“Fortunately no one involved in this incident suffered life-threatening injuries.”
