I found some rare fan footage of CART's infamous 2002 Australia race. For some context, CART ran on a street circuit in Gold Coast. Heavy rain was falling during the warm up laps and the race director opted for a single file rolling start. What followed could be described as CART's Spa 1997 start.

Thankfully everyone came out okay despite the numerous potential cockpit intrusions. One of the drivers interviewed said that he got launched into a barrel roll, but the broadcast cameras never caught this. This fan footage captured the crash including the barrel roll.

The race was red flagged and restarted for a shortened 50 laps. Unfortunately, 42 laps were run under the safety car. The best part is, the last driver who plowed into the crash ended up winning the race.
