It happened a few days ago, but Sir Frank Williams, founder and former team principle of the Williams Formula 1 team, passed away aged 79.
I'm a big fan of F1, and considering my first hero in the sport as a kid was Damon Hill when he was racing for Williams (eventually getting the title with them in 1996), this one hit me a little bit.
A real legend of the sport. Even after having been in the doldrums for the last decade, the team he built is still the second-most successful in F1 after only Ferrari.
