It was April 8, 1974 when Atlanta Braves outfielder Hank Aaron drove an Al Downing pitch into the bullpen of Atlanta Fulton-County Stadium to hit his 715th home run, breaking Babe Ruth's record.

Tonight the Braves will play the New York Mets and will commemorate Aaron's 40th anniversary moment.

Many ex-teammates and commissioner Bud Selig, who worked Aaron with the Milwaukee Brewers, will be in attendance.

Do you remember when Hank passed the Babe?
