Remember the good old Mercury days?
At T-15 minutes it was necessary to hold the count again to make a final check of the real-time trajectory computer. A small electrical part had a problem and this resulted in an hour and twenty six minute delay. Shepard was on top of the Redstone for so long now that he had to urinate. "Gordo!" he said, talking to Gordon Cooper, a fellow Mercury Seven astronaut and principal prelaunch communicator. "Go, Alan." "Man, I got to pee." "You what?" "You heard me. I've got to pee. I've been up here forever."
Shepard wanted to be let out but there wasn't time to reassemble the White Room. Thinking that he could be up there for hours, he told them he was going to do it in his suit. Unfortunately, there was no urine collection system and the medics were concerned he would short-circuit the leads. "Tell 'em to turn the power off!" Alan snapped. Cooper, with a chuckle in his voice said, "Okay, Alan. Power's off. Go to it."
Shepard couldn't hold back any longer and the liquid pooled in the small of his back. His heavy undergarment soaked up the urine, and with 100 percent oxygen flowing through the suit he was soon dry. The countdown resumed.
At T- minus two minutes and forty seconds and counting, Shepard heard that dreaded word again, "Hold". There was a little computer problem. Getting frustrated, he yelled, "I've been in here more than three hours. I'm a hell of a lot cooler than you guys. Why don't you just fix your little problem and light this candle?"
