A man had to parachute to the ground after his motorised paraglider experienced engine problems over Burgh St Peter.
The incident happened at around 7.15pm last night, with the aircraft coming down in a field off Dicks Mount.
Emergency services were called to the scene and a police helicopter was used to locate the man, in his 40s, and transport him to a waiting ambulance.
A police spokesman said: 'The man had ejected from a motorised paraglider after experiencing motor problems and used a parachute to come to ground in a nearby field.
'The police helicopter was used to locate the man who was taken to the James Paget Hospital by ambulance with a broken ankle.
'An investigation will be carried out by the British Hang Gliding and Paragliding Association.'
Two fire crews from Gorleston and Great Yarmouth were also called to the scene to help rescue the man.
A spokesman from the ambulance service said the helicopter was needed due to the difficult terrain, which was described as marshland.
