Defying Gravity, Defying Feardescribes one woman's journey to overcome a most innate fear-to climb one of the highest peaks in the world and then jump off.Heather Swan, executive and mother to four children, heard her mountaineer husband claim one day that 'anyone could jump off the highest cliff in the world'. Despite having had no mountaineering experience, she decided to be the one to take up the challenge. This involved an extraordinary mental and physical training program to prepare her to climb the Great TrangoTower in Pakistan and make a jump that would involve free-falling more than 1000 feet before opening a parachute and floating to a glacier below. The project became the subject of a televison documentary, BASEClimb 2.The issues of parental and individual responsibility provide a controversial backdrop. While some will see Heather as irresponsible for risking her life, others will recognise the importance of passionate living.
