Apollo 11 Moonwalker Buzz Aldrin was one of several famous pilots and aviation names 'flying' for UK disabled flying charity Aerobility in a simulated round-the-world flight challenge in October. In this video he answers questions on his aviation hero, the differences between flying a Piper PA-28 and a Lunar Module, and why humans need to make an all-out effort to walk on Mars.

The event, which began on 5 October has seen a round-the world flight divided into several legs to be flown in Aerobility's PA-28 simulator, which the charity is aiming to buy outright and support it from funds raised during the challenge.

His flight legs took him over Indonesia, and after his 'flight' he sat down to answer a few questions to the assembled media.
