Mitch Missen, an off-duty firefighter, witnessed the crash from his garden. He said: "I looked up and saw as both collided in mid-air, followed by a large bang and falling debris. "I rushed in to get my car keys and en route called the emergency services, who I continued to give updates as to its whereabouts.

There were a number of road closures following the crash but they have since been lifted. Seven fire vehicles from Aylesbury, Haddenham, Oxfordshire and Berkshire went sent to the scene.
