This story was related this morning at the Barrington, Illinois MacDonald's 6:30 am coffee klautsch and Republican Caucus. I trust the teller of the tale so well, I am not going to perform due diligence to look it up for confirmation.
During the early years of the "space race," NASA was befuddled because they could not figure out how to make a pen that could write in zero gravity. So, they spent a lot of time and money trying to eventually build one.
On the other hand, the Russians, recognizing full well the difficulties of the concept, decided to write down their space reports .... in pencil!
Way to GO Capitalism!
