On this day 39 years ago, a plane crash claimed the lives of three members of Lynyrd Skynyrd: lead singer Ronnie Van Zant, guitarist Steve Gaines and backup singer Cassie Gaines. One of the band's road managers was also killed, as were the pilot and the co-pilot, when the plane ran out of fuel and crash-landed in Gillsburg, Mississippi. Twenty people survived, although many were seriously injured. On the anniversary of the crash, we look back at some classic photos of the legendary band, which was inducted into the Rock and Roll Hall of Fame in 2006. AP

Van Zant performs at a concert in Atlanta in 1975. "Ronnie Van Zant was Lynyrd Skynyrd," songwriter Al Kooper wrote for Rolling Stone magazine. "I don't mean to demean the roles the others played in the group's success, but it never would have happened without him. His lyrics were a big part of it -- like Woody Guthrie and Merle Haggard before him, Ronnie knew how to cut to the chase. And Ronnie ran that band with an iron hand. I have never seen such internal discipline in a band." Tom Hill/WireImage/Getty Images

The band, from Jacksonville, Florida, was first formed as My Backyard in 1964. It changed names several times before settling on Lynyrd Skynyrd -- a name mocking Leonard Skinner, a high school physical-education teacher that was strict about the school's policy regarding boys with long hair.

Van Zant is interviewed in Atlanta in 1976. After the plane crash, the band broke up. It reformed in 1987 with Van Zant's younger brother, Johnny, as the new lead singer. It still performs today.

The band's "three-guitar lineup gave them an uncommon musical muscle, while their down-to-earth songs spoke plainly and honestly from a working-class Southerner's perspective," says their Hall of Fame biography.
