May 22, 1963, Yankee Stadium (the original of course), Mickey Mantle almost bombs a home run clear out of the park. Mantle considered this the hardest ball he ever hit. Bill Fischer was the pitcher off whom this satellite was launched, long before Launch Angle was a gleam in Sabermetricians’ eyes.
It followed by almost exactly seven years (May 30, 1956, though this date and “tail” are questionable) a similar home run that struck the Stadium facade on its descent. Funnyman Billy Crystal, who says he read the Torah in an Oklahoma drawl at his Bar Mitzvah, out of his Mantle-fandom, also claims to have been at that game with his father.
Surely announcer Mel Allen, the Voice of the Yankees, would have almost fallen out of the broadcast booth. Both times.
In My Favorite Summer 1956, Mantle notes that the 1963 ball cleared the wall 370 feet away from home plate (per the illustration), and that the Stadium roof was 117-feet high (not quite 118 feet, marked in the photo).
Estimates of a 600-foot or even 734(!)-foot blast had the Stadium facade not got in the way as the ball was still rising are possibly “over the top.” But this certainly was a shot heard round the world—or at least the Bronx. It is the stuff Legends (and Dreams) are made on.
