Leicester crash helicopter ‘appeared normal at take-off’
The aircraft reached the height of the stadium before it spun out of control and crashed, killing five people.
Nothing seemed “abnormal” about the helicopter carrying Leicester City boss Vichai Srivaddhanaprabha as it took off, moments before it crashed in a ball of flames, an aviation specialist has said.
Mr Srivaddhanaprabha and four others were killed in the crash outside the King Power Stadium on Saturday night following a game against West Ham.
The four other victims were employees Nursara Suknamai and Kaveporn Punpare, pilot Eric Swaffer and his partner Izabela Roza Lechowicz, who was also a professional pilot.
Footage obtained by The Sun taken from inside the ground showed the AgustaWestland AW169 ascending seemingly without any problems.

But as it climbs to the height of the stadium the fuselage starts spinning for a few moments before it plunges out of view.
Aviation expert David Learmount said the aircraft appeared normal at take-off, and it was only at the point the pilot tried to turn to leave the stadium that it seemed to get into difficulty.
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.
“The pilot climbed very nearly vertically until he was above the height of the stadium and then started to turn to the right – it was very shortly after that control was lost.
“Just after he did a manoeuvre that seemed to be intended, he lost control.”
By itself, the action of a helicopter’s main rotor would cause the body of the aircraft to spin in the opposite direction, as seen in the clip.
A second, sideways rotor fitted to the tail spins against the main rotor and keeps the body of the helicopter in a straight line, Mr Learmount said.
He added it was most likely that a fault had caused the second rotor to fail.
He said in those circumstances, a pilot’s only option is to immediately bring both rotors back to neutral.
“That leaves you with no power – if you have no power you have to go down,” he said.
“This action – bringing both rotors back to idle – has to be done incredibly quickly.
“If you shut the power down rapidly enough you can keep the rotor spinning and that effectively puts the helicopter into a glide.”
Mr Learmount said the emergency action is usually only effective if the helicopter has enough height, and in this instance the aircraft was probably not high enough.
“If you’ve already started spinning, trying to do all of this is very nearly impossible,” he said.
The Sun said the clip had been passed to the Air Accidents Investigation Branch (AAIB) which is investigating the crash.

Thousands of flowers and Leicester memorabilia have been laid by Foxes fans to commemorate Mr Srivaddhanaprabha and the other victims and a book of condolence has been opened.
The club has decided Saturday’s Premier League match against Cardiff will go ahead as planned.
There will be a minute’s silence before the 3pm kick-off and the players will wear black armbands.
The Duke of Cambridge was among those who paid tribute to Mr Srivaddhanaprabha.
On Tuesday, Leicester-supporting MPs expressed their sympathies in Parliament.
Labour former minister Keith Vaz and Northern Irish MP Jim Shannon led the tributes, thanking Mr Srivaddhanaprabha for the success he brought to the Foxes and his contribution to community projects.
