Surtees's incident is most likely what lead to the suspension of Renault for the next race.

Fernando Alonso's pit crew didn't properly replace the tire on the car during a pit stop and it came off on the track.

The worst part about the incident with Massa was that F-1 kept replaying the incident over and over. The in car cam on Massa's Ferrari caught the whole incident, from the spring hitting him, Massa losing consciousness, Massa coming to briefly, hitting the brakes, then hitting the barrier. They ran it in slow motion couple times, it really reminded me of the Theisman injury on MNF.

(For those who don't follow F-1, the feed broadcast on Fox and Speed here in the US is F-1's race feed with Speed's announcers calling the race. They talk about whatever Bernie's boys are feeding them)
