Guy Martin: Top Gun | Preview (Channel 4)

Guy Martin returns to Channel 4 with new one-off programme where he trains to fly a classic frontline fighter jet and builds a jet engine in his shed in a single day to gain an understanding of the technology's original creator, maverick British genius Sir Frank Whittle.

With jet travel being a major contributor to climate change, Guy looks for less damaging alternatives, before he heads off to the Swiss Alps and his final mission - to fly a fighter jet through the mountains

Guy Martin: Top Gun airs Sunday 24th August on Channel 4.
