Air show requirements 'should be reviewed'

Air display requirements should be reviewed as a precaution, a former senior official at the Civil Aviation Authority has said.

Captain Mike Vivian, who is also a former airline pilot, was speaking to the BBC after a plane crashed during the Shoreham Airshow.

Eleven people are now thought to have died after the vintage jet crashed into a main road in West Sussex, police have said.

The number of dead could rise further as police continue their investigations, the Sussex force has said.
