article: Aviation regulator the Civil Aviation Authority (CAA) has imposed new restrictions on airshows in the wake of the disaster - one of the worst of its kind in recent years. The Shoreham Airshow takes place annually at Shoreham Airport in West Sussex and is run by the Royal Air Force Association (RAFA). Some 50 aircraft, including many classic jets, were scheduled to take to the skies for display flights during the two-day event. Among them was a vintage Hawker Hunter jet, flown by pilot Andy Hill. Eyewitnesses say the plane had just begun its flight and was performing a loop when it failed to pull out of the manoeuvre and crashed into traffic on a busy main road, the A27, at about 13:20 BST. Footage captured by spectators at the airshow and nearby motorists showed a large fireball engulf the area. A major incident was declared, with one of the paramedics describing it as a scene of "utter devastation". 'Like a bomb exploding' - eyewitness accounts It is not yet clear what caused the crash, but eyewitnesses said the aircraft appeared to come out of the loop manoeuvre "too low". Shoreham resident Dave Penwarden, 51, saw the plane explode. "It just didn't seem to have enough speed to come out of the loop, instead of powering out it dropped too fast and hit the ground." Pilot Darren Sharp, who was a spectator at the event, told the BBC he believed the pilot had realised he was in trouble and made a "brave decision" to take the plane down away from the airfield where thousands of people were standing. Friend and fellow pilot Neil McCarthy said he believed Mr Hill had "the experience to roll out of the manoeuvre at the top and not complete it" if he lacked enough height. "The height looked high enough to me," he said. "But so many things can go wrong, there can be bird strikes, engine failure, an engine fire, there could be all sorts." The Hawker Hunter was a mainstay of the RAF through the 1950s and early 1960s. First flown in 1951, the single-seat plane was used as a fighter, fighter-bomber for reconnaissance and for aerobatics. There was also a two-seat trainer version, which served with many other air forces. Neil McCarthy said the precise type of aircraft was a 1950s Hawker Hunter T7, of which there were "probably only five flying at the minute", with Mr Hill one of only about six pilots who could fly it. The RAFA says all air display arrangements, including the pilots and aircraft, must meet rigorous Civil Aviation Authority safety requirements and are regularly reviewed to ensure they provide the highest possible levels of protection. Andy Hill, 51, from Sandon, near Buntingford in Hertfordshire, is a former RAF instructor and British Airways pilot. He is also an experienced aerobatic stunt flyer who has performed at shows up and down the country. Mr Hill was pulled from the burning wreckage, with multiple injuries. He was placed in a medically-induced coma and is now in a critical but stable
summary: At least 11 people were killed when a Hawker Hunter jet crashed on to the A27 during a display at the Shoreham Airshow.
