I haven’t seen this done before, and actually quite a good display.

Thousands of visitors have been wowed by a helicopter firework display during an air festival.

Brendan O'Brien flew Otto the Helicopter over the annual event in Bournemouth.

Cameras in the cockpit and mounted on the helicopter captured the display.

Organisers say this years event attracted an estimated 812,000 people

All of that in a heli powered by AvGas?

No, thank you, very much.
