THE F/ A-18 : A MULTI-ROLE FIGHTER The McDonnell Douglas F/A-18 Hornet was first developed in the early 1970s. They are twin-engine, all-weather fighters, equipped with both internal and external weaponry, including air-to-air missiles, air-to-ground munitions, and 6-barrel 20mm guns in their nose sections. A pair of General Electric F404 turbofan engines allow ultimate thrust, with the jets capable of reaching top speeds of Mach 1.8 - 1,034 knots or 1,190mph. The jets are able to be configured at speed and are used for attack missions, fighter escort, enemy air defence suppression, reconnaissance and air control. They were introduced on January 7, 1983 and cost between £18million and £37million. Advertisement

Patrick Turner, 72, of Redmere, told Cambridge News: 'I was outside in my shed and heard an aircraft coming over. All of a sudden all hell broke loose. 'The noise was terrible - I've never heard that before. 'There was a hell of a bang when it hit the ground. It shook all of the houses. It was so loud you could not hear yourself speak. 'I went outside and saw the plane - it was a huge fireball. 'The pilot bailed out and I saw the parachute coming down.' He added: 'The flames were huge. 'There was no way anyone was getting out of that alive. It's certainly not the sort of thing you expect on your doorstep. It was like something from a film.' His brother Anthony Turner, 73, a local farmer, said: 'I certainly heard it, it shook the house, my brother was outside at the time.

'The parachute that came over here went over the river so I don't know where that would end up.' Karen Miles-Holdaway, 48, who lives nearby, said: 'I was in my garden when I saw the plane going over. It was much lower than they usually fly at. 'I have so much praise for the pilot as I have heard he didn't make it. He took the plane away from the houses which was brilliant. This graphic - posted online - shows the route an arriving emergency helicopter took in getting to the stricken pilot 'We are just very grateful to him.' Another neighbour told MailOnline: 'I didn't see anything myself but there's a lot going on with police and helicopters. 'All I can see at the minute is blue flashing lights near a parachute. There's no plane in sight but I'm led to believe where the pilot is is around a mile-and-a-half as the crow flies to where it came down.' Asked if there was an obvious plume of smoke, the man said: 'It's been foggy and overcast this morning, so it's hard to tell.'

Despite the RAF prefix, Lakenheath is a United States Air Force base.

A US Air Force official at the airbase confirmed that an F/A-18 had crashed.
