In March 1929, Segrave went to Daytona, and after a sole practice run, on 11 March, in front of 120,000 spectators, set a new flying mile at 231.45 mph (372.46 km/h), easily beating Keech's old speed of 207.55 mph (334.00 km/h). Two days later, another record attempt by Lee Bible's "White Triplex" resulted in a crash which killed both Bible and a photographer. Daytona Beach was subsequently closed and Segrave was unable to make further runs to try for even higher speeds.
