An investigation into
the crash is being led by the Air Accidents Investigation Branch (AAIB), which investigates civil aircraft accidents across the UK.
The investigation will look into how the Agusta Westland AW169 helicopter crashed in what is believed to be the first accident involving an AW169 aircraft.
The owners have two helicopters – an older one registered as G-LCFC and a newer one registered as G-VSKP.
The helicopter that landed at the stadium was the G-VSKP.
Jim Rowlands, a former RAF Puma crew member, said the spinning nature of the aircraft indicated there was a problem with the tail rotor – the part of a helicopter that normally stops it from spinning around in the opposite direction to the main rotor blades.
„If you lose your tail rotor it’s almost impossible to recover from,” said Mr Rowlands.
„You can’t get out of it. It would be more luck than judgment if you were to survive.”
His „gut feeling” was there was some kind of mechanical problem but said there were „so many things that it could have been”.
„It could have been a human factor, it could have been pilot error or poor maintenance that led to something,” he said.
An AAIB spokesperson said: „A team from the AAIB has been deployed to the site and is investigating.
„Anyone with information that might be helpful to the investigation is asked to contact the police.”

The Duke of Cambridge led the tributes to Mr Vichai on Monday, saying he was lucky to have known him for several years.
„He was a businessman of strong values who was dedicated to his family and who supported a number of important charitable causes,” Prince William, who is president of the FA, said.
„He made such a big contribution to football, not least through Leicester City’s magical 2016 season that captured the imagination of the world.”
Former Leicester City and England striker Gary Lineker tweeted to say he was „deeply saddened” to hear of Mr Vichai’s death. He signed off the Match of the Day programme on Saturday by saying it had been a „dreadful day”.

Speaking outside the stadium, club ambassador Alan Birchenall said Leicester City owed „everything” to Mr Vichai.
„I had to pay my respects to a lovely guy,” he said. „We owe everything to him. We wouldn’t have won it [the Premier League] without him. We wouldn’t have got near it without him.
„There won’t be a dry eye among any of the staff today.”
Mr Swaffer’s friend Lucie Morris-Marr said the pilot was a „veteran in the field” and would have done all he could to prevent lives being lost in the crash.
She described him as a „funny and vivacious” man who was in an „aviation love story” with Ms Lechowicz.
The couple were professional pilots who lived together in Camberley, Surrey. Ms Lechowicz moved to the UK from Poland in 1997.
In a statement, the Polish embassy said: „She [Mrs Lechowicz] was a great pilot, winner of the #Polka100 contest. It contributed to the creation of a positive image of Poland in the UK.”
Prime Minister Theresa May said: „The outpouring of grief is a testament to how many people’s lives were touched by those on board.”

Season ticket holder Richard Jackson, of Market Bosworth, said he was „devastated” by what had happened.
„These owners have been absolutely fantastic; probably the best owners in the whole English system,” he said.
One fan said of the family: „They are the heart and soul of Leicester City Football Club.
„If it wasn’t for them none of this would have been possible in recent years and dreams wouldn’t have come true.
„It’s very disturbing, not just for fans of the club but for everyone in the football world.”

Richard Mobbs, from Burton Overy in Leicestershire, said he last saw the chairman in June when they discussed a player who was about to join the club.
Mr Mobbs described Mr Srivaddhanaprabha as a „lovely, quiet, down to earth man”, and paid tribute to his family.

Anupat Maturongpituck, a student from Thailand studying at the University of Leicester, came to the King Power Stadium on Sunday to „pay my respects”, adding news of the crash has had a „great impact” in Thailand.
Mr Vichai has regularly given supporters free beer and pies at matches to mark special occasions, made donations to the city hospital, and treated the 2016 title-winning squad to a fleet of blue BMWs.
Another fan said: „It’s ended up as probably the darkest day in Leicester City Football Club’s history.”
