As Commander of the Thunderbirds, Lt. Colonel Ron Mumm asked Paul Fisher to design a pen with a "gripping knob" to allow easy removal and replacement from the small, lower leg pocket of the pilots' flight suits. Today, this pen is the official writing instrument of Thunderbirds pilots. The Thunderbirds logo sits atop the gripping knob of the pen. Otherwise it's a regular AG7 model pen as used on all the manned space flights.About Fisher Space Pens
The Fisher Pen refills were developed by Paul Fisher just after WWII due to the ball point refills of the time being leaky and unreliable. He then went on to develop his own range of pens.
Paul Fisher had a mission in mind for his pen - he introduced his new unique pen cartridge to NASA! The Fisher Pen underwent extensive testing and was subsequently approved for a trial mission in outer space. In 1968 the Fisher Space Pen was whole-heartedly approved and ordered for use by astronauts on ALL MISSIONS IN OUTER SPACE.
The Fisher Space Pen is still used today on all manned space flights.About Fisher Space Pen Refills
