49 years ago today...the launch of Apollo 11 and the trip to the moon

My uncle worked at TRW and was a weights and measurements engineer. The found they were 3 grams light very late in the game so he and some guys slapped some gaffers tape on the bottom of the Voyager satellite and signed it. There's your 3 grams. Imagine, your signature leaving the solar system! He told us that story a long time ago and I remember it to this day.
