Bobby Unser is interviewed after qualifying his Lightning 77/Offenhauser TC second fastest for the "500" in 1977. Despite his front-row starting position, Unser led just two laps before dropping out of the race after 94 laps. High attrition during the '77 event allowed Unser to finish 18th, in spite of completing less than half the race.
Janet Guthrie drew a great deal of attention during practice for the 1977 event, and even more after she became the first woman to qualify for the Indy 500. Driving Rolla Vollstedt's Lightning 76 1/Offenhauser TC, Guthrie posted the fastest speed on the final day of qualifying.
