A helicopter carrying Leicester City chairman Vichai Srivaddhanaprabha and four other people crashed moments after lift-off.
In the footage the aircraft can be seen coming out of the King Power stadium just after 8.30pm on Saturday as it lifted off from the pitch.
It rises slowly above the trees surrounding the stadium and goes out of the screen's view for 12 seconds.
A bright light from the front of the helicopter then suddenly comes back into view.
It only took three seconds for the helicopter to reach the ground in car park E after returning to the CCTV camera's view.
He said: "The next thing I just looked up and it was just spinning, static just out of control, just a constant spinning, I have never seen anything like it.
"I don't know how the pilot did it but he seemed to manage to slow down the spinning rotation and it drifted off into the corner part of the car park.
"To my mind the pilot was heroic and the two police offers in front of me, who also tried to help, they are heroes too.
The much-loved Thai billionaire died alongside the other four people on-board - pilot Eric Swaffer, his girlfriend and fellow pilot Izabela Roza Lechowicz, Nursara Suknamai and Kaveporn Punpare, who both worked for Mr Srivaddhanaprabha.
The ever-growing mass of flowers, shirts and notes outside the stadium displaying the popularity of the owner, who turned the club's fortunes around.
There was a hushed silence before fans broke out into applause for the squad, who were joined by the owner's son and club vice-chairman, Aiyawatt, known to supporters as "Top".
Earlier in the day, Top and Mr Srivaddhanaprabha's wife walked carefully through the tributes to lay a wreath of their own.
Supporters continued to turn up at the stadium throughout the day, and with a book of condolence to be opened later this week, the flow of fans is set to continue.
