Pilot Andy Hill has been at the centre of the police investigation into the Shoreham Airshow disaster which claimed the lives of 11 men one year ago.

He was badly injured when his Hawker Hunter T7 jet crashed on to the westbound carriageway of the A27 after a failed manoeuvre.

The pilot spent weeks in an induced coma but miraculously survived and has been recovering.

He was first spotted on his feet again last October when he was pictured walking in jeans and denim shirt, carrying a water bottle.

Police interviewed him under caution last December. He was not arrested

Then five months after the August 22 tragedy, images emerged of him driving on rural roads in Kings Langley, close to where he lives in Hertfordshire, in a £40,000 Porsche Boxster sports car.

Last month The Argus reported the 52-year-old was being investigated over possible manslaughter charges. The pilot has been told his conduct is also being looked into on suspicion that he endangered lives under strict air navigation laws.

We know he is a former British Airways captain, a skilled aerobatic flyer who is a regular at airshows up and down the country.

He is a highly skilled former RAF instructor with more than 12,000 hours of flying experience.

Mr Hill has flown for years, having worked as a light aircraft test pilot, an RAF Harrier GR7 instructor, a commercial pilot captaining Airbus planes and as a stunt and aerobatic display pilot. He has worked as a pilot offering flight experiences to the public for the company Ultimate High.

According to its website he began his career flying Bulldogs in a university air squadron and after excelling on fast jet training, was picked to go straight into instructing on the BAC Jet Provost, a jet-powered trainer aircraft.

He then operated the Harrier GR5 and GR7 jets in Germany and has flown Airbus A340 and Boeing 757 and 767 airliners, working as a captain for Airbus.

Ultimate High’s website said: “He is a very experienced formation instructor and display pilot and regularly displays the RV-8, Jet Provost and Hunter.”

Mr Hill also worked as an aerobatic stunt pilot as part of the flying duo the RV8tors, who perform close-formation aerobatic displays at speeds of up to 230mph.

The RV8tors – Mr Hill and fellow display pilot Alister Kay – performed at events, private functions and weddings in RV-8 aircraft, small two-seat, home-built planes.

A profile of Mr Hill on the company’s website said: “In 2011, as well as displaying with the RV8tors, Andy flew formation displays in the Hunter and Bulldog, and solo aerobatic displays.

“Andy and his wife Ellie took two years to build their RV-8, both are airline captains with over 12,000 hours each, and now building an RV-3.”

But detectives investigating the Shoreham Airshow disaster are looking into an incident at the Southport Airshow in 2014.

It is understood to have involved a Jet Provost reportedly flown by Hill over crowds while doing a loop manoeuvre, although that has not been officially confirmed.

David Walton, flight director of the airshow in Southport, told ITV News: “During the display by a Jet Provost T5 at the Southport Airshow the aircraft was observed to be inside the lateral separation minima for the event and also below the minimum height stipulated in the Article 162 Permission issued by the CAA.

“A ‘stop’ call was immediately issued by the Flying Display Director (FDD) on the display radio frequency and the flying display was terminated.

“The pilot was debriefed, initially on the telephone and later in person, and agreed to amend his display for the Sunday display.”

The initial Air Accidents Investigation Branch (AAIB) bulletin into the doomed Hawker Hunter flight in Shoreham found the fatal loop-the-loop was performed hundreds of feet lower than the pilot’s licence allowed before it crashed.

A risk assessment for the 2015 Shoreham Airshow did not “show the range of hazards presented by different display aircraft”, the Air Accidents Investigation Branch (AAIB) has said.

The AAIB has found Shoreham’s flying display director was unaware of the sequence of manoeuvres Mr Hill intended to perform.

The AAIB examined video footage of a Hawker Hunter display at Shoreham Airshow in 2014 and found the aircraft overflew residential areas along the A259 south of Shoreham Airport several times and in one manoeuvre overflew the central area of Lancing at an angle of bank in excess of 90 degrees.

Either these regulatory infringements were not detected by the display organisers or were not understood. It is not clear who the pilot was that day.

Mr Hill has previously stated that he will not answer questions from the press.
