AG7 The pen that went to the Moon!
When astronauts started to expore the reaches of outer space, Paul Fisher realised that no existing pen coulde perform in its zero-gravity vacuum and temerature extremes. His common sense approach and practical experiments resulted in the invention of the sealed- pressurised Fisher AG-7 "Anti-Gravity" Space Pen. After rigorous testing, NASA selected the Fisher Space Pen for use on all of the Apollo missions. They are still used on manned flights in outer space.
The AG-7 Space Pen series are all metal, 10mm diameter, 130mm long, with a side button release mechanism.
The Shuttle Space Pen series are all metal, 8mm diameter, 133mm long, with a side button release mechanism.
In July 1969, the Apollo 11 space mission used the Fisher Space Pen to fix an arming switch that was crucial to bringing back the Astronauts safely back to earth.
