For those who don't know, Fisher makes the Space Pen, using their pen ink cartridge that is pressurized to write upside-down or in zero-gravity. The ink is specially formulated to write on most any surface, even grease, and can even write underwater. It is also designed to hold up against temperature extremes and at high altitudes. It has indeed been a pen used in NASA space missions for decades (before that, pencils were used but the leads would break off and there was a concern that they would cause a problem to instruments).
I have 3.
- A blue "bullet pen" to replace the silver one I lost on the way back at '07 Comic-Con,
- a black metal anti-glare military "cap-o-matic" pen (for when I need to write documents without being seen by snipers I guess),
- and a classic Fisher "Astronaut pen" with a spiraling graph etched deco that my grandparents gave me.
I've never had a Fisher pen run out of ink on me, I always lose them first.
So, who else has 1 or more of these things, thus proving their true nerdom?
