Footage from cockpit cameras in the vintage jet involved in the Shoreham air disaster has revealed the aircraft showed "no abnormal indications" during the flight, according to air crash investigators.

The "special bulletin" by the Air Accidents Investigation Branch (AAIB) also reported that the video showed the Hawker Hunter jet "appeared to be responding to the pilot's control inputs".

Eleven people died when the plane plummeted on to the A27 in West Sussex during the Shoreham Airshow on August 22.

The jet failed to pull out of a loop-the-loop stunt before crashing on to the road, exploding into a fireball.

The AAIB said there were two "image recording cameras" mounted within the cockpit.

One was located between the two seats, giving a partial view of the pilot and instrument panel, as well as a view through the cockpit canopy and windscreen.

The report stated: "To date no abnormal indications have been identified.

"Throughout the flight, the aircraft appeared to be responding to the pilot's control inputs."

The other camera was mounted at the base of the windscreen looking over the nose.

The preliminary report noted that investigators have received a "large amount" of video and photographs of the aircraft from various locations around Shoreham Airport, where the airshow was taking place.

Many of these are in high definition are will be analysed in a bid to determine the jet's manoeuvres, including flight path and speed.

The AAIB said the pilot carried out a pre-flight inspection before taking off from North Weald Airfield, Essex, to fly to Shoreham and there were "no reported defects".

The document added: "The pilot was described as being in good spirits and looking forward to the flight."

The jet's pilot, Andrew Hill, was left fighting for his life and has been moved to a specialist hospital for treatment.

Wreckage from the crash has been sent to the AAIB's headquarters in Farnborough, Hampshire.

The victims have been named as retired engineer James Graham Mallinson, 72, from Newick, near Lewes; window cleaner and general builder Mark Trussler, 54, from Worthing; cycling friends Dylan Archer, 42, from Brighton, and Richard Smith, 26, from Hove; NHS manager Tony Brightwell, 53, from Hove; grandfather Mark Reeves, 53, from Seaford; Worthing United footballers Matthew Grimstone and Jacob Schilt, both 23; personal trainer Matt Jones, 24; wedding chauffeur Maurice Abrahams, 76; and Daniele Polito, 23, from Worthing.

The inquest into their deaths was opened and adjourned at a hearing in Horsham on Wednesday.
