Almost exactly 40 years ago, on 06.02.1971, Alan B. Shepard succeeded the furthest one-handed golf swing in history to date, as commander of the Apollo 14 mission. He did not accomplish this due to any extraordinary abilities as a golf player, but because he struck the golf ball on the moon. And because of the prevailing, scarce amount of gravity and the absent braking effect in the atmosphere, the ball flew extremely far.
Shepard had to strike the ball one-handedly, as the rigid space suit did not allow two-handed play. He undertook four attempts and struck two balls altogether. How far exactly they flew has not been documented, however, one can assume a couple of hundred metres. In the original audio material of NASA, you can hear Shepard saying jokingly, after his last tee off »Miles and miles and miles …«.
