1: Life on the Limit examines the difficult and controversial history of safety in Formula One.
From its earliest days F1 attracted the best and brightest drivers and saw them pitted against each other in cars that were at, or beyond, the cutting edge of technology.
Especially in the days before purpose built circuits predominated the result was tragically inevitable - many drivers paid the ultimate price for the speed, fame and glamour that went hand in hand with racing.
As speed and the pressure to succeed increased drivers started to push back against the perceived lack of interest in their safety from teams and organisers.
With people like Jochen Rindt and Jackie Stewart leading the charge F1 as we know it today started to emerge. But it was not without severe birth pains that the safety regime that has protected drivers since the fatal crashes of Ratzenberger and Senna at the San Marino Grand Prix in 1994.
Packed with interviews with key players including Max Moseley, Bernie Ecclestone, Jackie Stewart, Damon Hill, Jacky Ickx, Nigel Mansell, Michael Schumacher and the indomitable Professor Sid Watkins, this documentary shows the true cost of the glamourous side of F1 and the price too many drivers paid for it.
