Steer Road in Wolferton remains blocked as investigations into the crash, which happened just before 11am on Monday, September 11, begin by the Air Accidents Investigation Branch (AAIB).

The aircraft's pilot in his 50s and a female passenger in her 70s died after reports of a crash landing of what was believed to be a four-seater Piper Arrow on marshland near Wolferton, near King's Lynn.

Emergency services were called and the pair were pronounced dead at the scene.

Postman Anthony Pittam, 43, was near Steer Road, on Monday morning at around 11am when he heard a plane.

He said: 'The plane was really low, the clouds were really low and it was quite windy. Not best conditions at all - visibility was not great.'

Mr Pittam said the plane flew in the direction of the sea bank from the cottages.

He said the village was soon filled with police, ambulance and fire engines.

He added: 'It was about 10 minutes, it was really quick.

'I didn't hear a crash. I came round [Steer Road] and there were people here and they said I wonder if the plane had come down. Apparently it hit a tree.'
