Friday Hassler

Hassler is prominently featured in the 1975 book The World's Number One, Flat-Out, All-Time Great Stock Car Racing Book by Jerry Bledsoe.

Hassler died of injuries sustained as a result of a 13 car-pileup during the first qualifying race of the 1972 Daytona 500 at the age of 36 and at the peak of his career. It happened on lap 19 when the No.57 Dodge of David Ray Boggs blew his right rear tire. Caught in the pileup, Hassler spun his No.39 Chevy into the infield grass before swerving back into the track and slammed into the outside wall head-on. His car rebounded and as it continue to spun out on the track, with other drivers still pilling into the crash scene, he was then broadsided on the passenger side door by the No.54 Dodge of Jimmy Crawford, the impact catapulting the car back into the wall. Hassler was killed instantly from massive head and neck injuries.

At the 1971 Volunteer 500 at Bristol Motor Speedway, Hassler was a relief driver for race winner Charlie Glotzbach. It was not an official win for Hassler, and it is one of only three instances when two drivers drove the winning car in a NASCAR premier series race.

Hassler made his debut in 1960 but only drove a handful of races per year until 1967 when he drove 21 of the 49 races for Red Sharp and finished 32nd in points. He improved to 27th for Sharp the next year and drove his own car in 1969 to a 28th-place finish. In a late model car at the end of the year, he scored a win in the second annual Snowball Derby, now regarded as one of short track racing's most prestigious races. In 1970 he drove for James Hanley and finished 20th in points. His best season was 1971, when he drove his own car to 13 top ten finishes and a 16th place points result.

Raymond "Friday" Hassler (July 29, 1935 – February 17, 1972) was a NASCAR Grand National and Winston Cup Series driver.
