SAFETY restrictions banning vintage aircraft from performing loop-the-loops and other aerobatic stunts over land will not affect the Scottish Airshow next month, organisers have said.

The Civil Aviation Authority announced a crackdown on UK airshows while the authorities continue to investigate the Shoreham air disaster, which is believed to have killed up to 20 people.

The CAA said vintage jets would be limited to flypasts over land "until further notice", meaning that the sort of high energy aerobatics which ended in tragedy on Saturday will be prohibited.

The regulator added that it will "conduct additional risk assessments on all forthcoming civil air displays to establish if additional measures should be introduced".

However, Doug Maclean, spokesman for the Scottish Airshow Ltd, said the Prestwick spectacular would be able to go ahead as planned since all stunt flights are performed over the sea off Ayrshire.

The two-day event, which was relaunched for the first time in 22 years last year, is due to take place on the first weekend of September and is expected to attract some 100,000 visitors. It will include an aerobatics display on Saturday September 5 which will see the return of the Red Arrows for the first time since 1992, and the final aerobatics display by the vintage Vulcan bomber jet before she enters retirement.

Mr Maclean said: "The Scottish Airshow is a different from Shoreham in that everything here takes place over the sea, rather than over land.

"The aerobatics on Saturday will be over the sea with visitors able to watch from the promenade or the beach.

"The reason this incident [in Shoreham] has attracted so much publicity is because these types of tragedies are so rare at airshows. The last major incident at an airshow in the UK where people on the ground were killed was at Farnborough in 1952.

"There are around 700 airshows a year around the world and they are very safe. We can reassure the public that the Scottish Airshow will meet the very highest safety standards."

The Farnborough airshow disaster claimed the lives of 29 spectators and both crew members after a prototype de Havilland DH.110 suffered a fault and broke up in mid-air.

The incident in Shoreham also comes weeks after a stunt pilot was killed when his plane spiralled out of control and crashed into trees during a display at a car festival in Chesire. No one on the ground was injured.

Police warned that the death toll from Saturday's crash in Shoreham could rise to 20 as teams begin recovering the plane's wreckage. At least 11 are known to have died.

A crane has begun to lift debris scattered when the 1950s Hawker Hunter jet exploded in a giant fireball as it ploughed into traffic on the busy A27 in Sussex after failing to pull out of a loop-the-loop stunt.

Pilot Andrew Hill is fighting for his life after being put into a medically induced coma. His family said they are "devastated and deeply saddened for the loss of life".

Three people - Worthing United footballers Matthew Grimstone and Jacob Schilt, both 23, and 24 year-old personal trainer Matt Jones - are among the dead.

Motorcyclist Mark Trussler, from Worthing, is missing, while fears have also been raised over Daniele Polito, a father from Worthing who was travelling in the same car as Mr Jones when the plane crashed.

The driver of a Daimler wedding car, 76-year-old Maurice Abrahams of Brighton, a former soldier and police officer., is also believed to be among those killed.

West Sussex coroner Penny Schofield warned that work to identify the victims may take "several weeks".
