1975: Mario Andretti was racing full-time in Formula One in 1975, which created conflicts with the schedule at Indianapolis. Andretti missed pole day due as he was at Monaco, where he dropped out. Mario returned to qualify on the second weekend of time trials. He had the seventh-fastest speed, but as a third day qualifier, he would line up 27th. On race day, Mario suffered handling problems early on which sent him to the pits. While exiting the pits, the car stalled several times due to a clutch issue, and the crew had to pull the car back to its stall. The crew bled the clutch, which cost Mario nine minutes in the pits, and he lost several laps out on the track. On lap 68, a sudden mechanical failure sent his car crashing hard into the inside wall on the backstretch. Sid Collins, on the IMS Radio Network, even begun suggesting that bad luck had been following Andretti since his 1969 win. Mario skipped the Belgian Grand Prix to race at Indy.
