During his prime, Killebrew was a slugger of mythical status. In American League cities, fathers would take their sons to the ballpark and point to places Killebrew reached with his prodigious power. He once hit a ball over the left-field roof at Tiger Stadium. When he returned to the hotel, he had messages from six different people who claimed to have the souvenir. They didn't know the head groundskeeper had walked out behind the stadium, found the ball resting near a drain pipe, and gave it to Killebrew as a keepsake.
I once saw him hit one in the old Yankee Stadium that the shortstop jumped for; it hit the outfield wall so hard that it bounced back to the left fielder, and Killebrew had a single. He was slow, but that ball must have bounced back 200 feet.
