Ah, that was a wild one, all right.
That whole '85 season was fantastic, with Andretti, Rahal, Sullivan, and both the Unsers all taking shots at the championship... It came down to the last race at Miami, with Al Unser beating his son by 1 point in the championship, by making a daring pass around Roberto Moreno with 3 laps to go. It also featured a good sparring match between Rahal and Sullivan, Bobby leading most of the race but failing to hold off the Penske driver once his tires started to blister.
Interestingly, Alan Jones, then still an F1 driver for Lola, was actually brought in for a race at Road America as a replacement for the injured Mario Andretti!
Unser Sr. probably wouldn't have been running during the season at all had Rick Mears not nearly destroyed his feet in a crash at Sanair the previous season, which put him out for much of the '85 season, and have always troubled him since.
Hey, something I found while browsing the web.
This is a Penske testing at Pheonix in the winter of 1992. But look close at that helmet.
What might have been at Indy?
