In 2002, free diver Tanya Streeter attempted to set a No Limits world record by diving down to 160m and resurfacing, all on a single breath. She would have to survive the pressures of the deep and hold her breath for 3 and a half minutes. It almost went wrong. Tanya Streeter spoke to Alex Last in 2015.
