Charlie Whiting's sudden passing in Melbourne on this day five years ago shocked the F1 community and cast a dark shadow over the 2019 season-opening race.
As a man who placed the safety of F1 and its drivers at the forefront of his concerns, and as a natural confidant for many in the paddock - team managers and drivers alike - F1's resident race director is still sorely missed.
Many believe the outcome of of F1's season finale in Abu Dhabi in 2021, and therefore the championship, would have been quite different and void of controversy with Charlie at the helm.
Look back on his distinguished career in the sport, Whiting had lived the life of a mechanic with several teams, moving up the ranks to work for Brabham in the 80s.
There, along with genius designer Gordon Murray, he was Nelson Piquet's side-kick and most precious ally, with the trio celebrating two world championship titles together with Bernie Ecclestone's outfit.
