As I watched that today, it didn't seem possible that I watched his 1st race (racing in a Jordan at Spa 1991) some 15 years ago! What a run he's had. There were a few years there where direct comparison's with Prost and Senna could be made. Schumacher always held his own, usually in inferior equipment.

Another interesting video while we're at it, showing Senna storming out of a driver's meeting just before he takes out Prost on purpose at Suzuka 1990.
