Leicester City helicopter crash: 'Operating normally' on take-off Leicester City helicopter crash: Aircraft 'spun' after take-off
(about 4 hours later)
The helicopter carrying the Leicester City owner appeared to be operating normally moments before it crashed, an expert has said. Video footage of the helicopter carrying the Leicester City owner shows it spinning moments before it crashed killing him and four others.
Vichai Srivaddhanaprabha and four others were killed in the crash outside the King Power Stadium on Saturday. Vichai Srivaddhanaprabha died along with two members of his staff, the pilot and a passenger in the crash outside the King Power Stadium.
Aviation expert David Learmount said a widely shared video showed the aircraft complete an "awkward" take-off without issue before getting into difficulty. The video shows the aircraft going into a spin, which experts said suggests a problem with the tail rotor.
Crash investigators are expected to move the wreckage in the next few days. Investigators would not comment on the video or causes of Saturday's crash.
As well as Mr Vichai, Nursara Suknamai, Kaveporn Punpare, pilot Eric Swaffer and his partner Izabela Roza Lechowicz also died in the crash. The widely shared footage, taken inside the stadium, shows the AgustaWestland AW169 climbing normally for about 40 seconds, before it pauses and goes into a downward spin.

Mr Learmount said: "At lift-off you can't see anything that's abnormal, but it's an awkward job climbing out of a stadium because ideally you want some forward speed as well as continuing to climb.

Attention is focusing on the tail rotor, which stops the fuselage being spun by the force of the main rotor.
Mr Learmount said if the tail rotor was the problem, the pilot's options were limited to simply shutting power off to the rotors.Mr Learmount said if the tail rotor was the problem, the pilot's options were limited to simply shutting power off to the rotors.
"That leaves you with no power - if you have no power you have to go down," he said."That leaves you with no power - if you have no power you have to go down," he said.

All five occupants of the helicopter were pronounced dead at the scene of the crash.

The Air Accidents Investigation Branch (AAIB) is already examining the flight recorders, which were retrieved the day after the crash.The Air Accidents Investigation Branch (AAIB) is already examining the flight recorders, which were retrieved the day after the crash.
A huge display of floral and footballing tributes have gathered outside the stadium and a steady stream of people have signed a book of condolence. It said it was "too early" to comment on the video or the possible causes of the crash and said it "will consider a wealth of evidence, and the video is just one element".
Family, players and members of the wider Leicester community have also visited the scene. A spokesperson for Leonardo, the Italian company which manufacturers the AW 169 said it was working closely with the AAIB and British authorities.
So far it has not issued any new safety advice, relating to the AW169, in light of the crash.
On Wednesday, coroners for Leicester said formal identification of 60-year-old Mr Vichai and 32-year-old Nursara Suknamai had taken place.
Others are still in progress and no date for inquests has yet been set.

A minute's silence will be held and black armbands will be worn by players at all Premier League matches this weekend as a mark of respect, the Premier League has confirmed.A minute's silence will be held and black armbands will be worn by players at all Premier League matches this weekend as a mark of respect, the Premier League has confirmed.
Leicester players will travel by road to their game at Cardiff on Saturday rather than fly, as going by plane was felt to be insensitive given the circumstances of Mr Vichai's death.
