Dale Earnhardt
Toward the end of the 2001 Daytona 500, Earnhardt and Ken Schrader slid off the track. Schrader was able to get out of his car and immediately signaled for the emergency unit to help Earnhardt. A few hours later, NASCAR president Mike Helton made the official announcement that Earnheardt had passed away. (AP Photo/Toby Talbot)
