Helicopter crashes at navy base
The crash happened near the base's control tower
A helicopter has crashed at a Royal Navy base in Cornwall.
The incident happened at RNAS Culdrose, near Helston, at about 1500 BST on Tuesday when a Merlin helicopter hit the ground near the control tower.
One man was trapped in the aircraft and flown to hospital. Four other people were slightly hurt in the incident.
The £60m anti-submarine aircraft, which is thought to belong to 824 Squadron, had just taken off on a training flight.
Road closed
Two civilian fire engines were sent to the base but were not required. Civilian ambulances were also called to assist navy paramedics.
The main road from Helston to the Lizard has been closed as a precaution.
The Merlin, which was first introduced in 1997, normally carries a crew of three comprising a pilot, observer and aircrewman.
The 22.8 metre-long aircraft has a rotor diameter of 18.6 metres, weighs 14,600 kilograms and has an anticipated service life 35 to 40 years.
RNAS Culdrose is responsible for training helicopter pilots, observers and aircrewmen in search and rescue, weather forecasting and aircraft handling.
