Jenson Button MBE, or ‘JB’ as he’s known on Planet F1, did not have a job in the winter of 2008. A year later he was world champion, having won six of the first seven races of the 2009 season. His team, Brawn GP, won the constructors’ title in its first and only year in the sport. You simply could not make this up, a momentous and unique achievement that’s a chapter of its own in motor racing history.
