At least 11 people were killed when a Hawker Hunter jet crashed on to the A27 during a display at the Shoreham Airshow.
Aviation regulator the Civil Aviation Authority (CAA) has said it is considering whether safety requirements should change as a result of what happened at Shoreham, one of the worst air show accidents 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".
