Hard to believe that it is 40 years ago today since a foggy night in the mid 1970s, when the world of motor racing lost a double world champion hero along with a probable future champion and four of their teammates.
I well remember the disbelief and shock at the news that Graham Hill - he of the raffish moustache, swashbuckling personality and prodigious talent - had gone down in a plane crash in thick fog at Elstree airport, on the evening of 29 November 1975.
With him in the plane were very promising young driver Tony Brise, team manager Ray Brimble, designer Andy Smallman, and team mechanics Tony Alcock and Terry Richards.
Hill's son Damon was just 15 at the time. How proud his dad would have been to know that his teenage son would follow in dad's tyre tracks as a future Formula One world champion.
