Thunderbirds Space Pen

Any guy knows that the Thunderbirds pilots have the coolest jobs in the world. Lt. Colonel Ron Mumm not only got to pilot one, he also convinced the Fisher to make a specialty pen for Thunderbird vets like himself. The result is this variant that features a gripping knob, allowing for easy access from the pilots’ small lower leg pocket.

The original Space Pen was tested by NASA for two years before becoming the official pen of the Apollo 7 Space Mission in 1968. The pressured ink cartridges allow for smooth, dark lines even at extreme angles. Write on wet or greasy paper, draw upside down, and even sketch in zero G. This pen can handle whatever your hands can throw at it.

In the quest for a perfect ink refill, Paul Fisher developed a prototype that used thixotropic ink and a cartridge pressurized with nitrogen, so that it didn't rely on gravity to make it work. The result was a pen that was dependable in freezing cold, desert heat, underwater, and — of course — outer space. Beginning with the October, 1968 Apollo 7 mission, NASA began using the Fisher AG-7 Space Pen and cartridge, cementing the pen’s legendary status.
