For me, it would probably be seeing Robert Kubica's accident at Montreal in 2007. Obviously he survived and only missed a single race, but it's quite a shock to see something that violent unfold as you watch and then notice that the grandstands around you are totally silent while everyone waits for him to move to make sure he's alive. There was quite a cheer when they extracted him from the car and carried him off on a stretcher with his arm waving.
It was also pretty special to see Lewis get his first pole and win in 2007, and Robert his first and only win the next year.
In sportscars, I think the most significant thing I've seen in person was the debut of the Audi R8 at Sebring in 2000. It won its first race, and that was the start of an era of absolute domination by Audi that hasn't really ever stopped with the exception of some bumps in the road by other works teams. I remember standing trackside at T1 when the race started and watching the R8s just gliding through that bumpy corner as the BMWs and the rest of the prototypes skittered all over the track. It was clearly a huge step above anything that had been developed to that point for that ruleset, and the team had this aura about them all weekend.

That's my view of the aftermath of Robert's wreck.
