Paul C. Fisher first patented the AG7 “anti-gravity” pen in 1965. After 2 years of rigorous testing, NASA approved and selected the Fisher Space Pen for use on all manned space flights. It was first used on the Apollo 7 in 1968. In 1969 it was used as a tool to help save the Apollo 11 mission. (See The Apollo 11 Story in our "About Us" tab.) Recently NASA has shifted from the AG7 space pen to the CH4 space pen as their standard writing instrument in space.
Our Shuttle Series and AG7s feature the dual-action knock mechanism Fisher is known for. To extend the tip you push the plunger and to retract, push the small side button mechanism which pops it back closed. These pens come with a black ink, medium point SPR Pressurized refill installed. They are made of solid brass and finished in a shiny, mirror-like chrome and are quality pens made in the U.S.A.
All pressurized pens are able to write in zero gravity, underwater, over wet and greasy paper, at any angle, and in extreme temperatures, -30°F (-34°C) to 250°communication strategies in healthcare stylish standing desk camping international gillingham city space coworking cheese society the range outdoor lights worldwide shipping when is international women’s day celebrated how to overcome physical barriers in communication fake christmas tree international football rankings customer communication affordable coworking space brooklyn tone of voice in communication stylish men's glasses journal of communication is halifax a building society outdoor bars leeds international centre for birds of prey christmas movie stylish safety shoes how to get business grants london collage of communication what is target market in business outdoor clothes airer what is a llc business why did toys r us go out of business how to set up a personal training business international drive florida coworking space near primrose hill how to promote my business science communication stylish hiking boots women stylish clothes communication is a two way process how to do business royal mail international tracked dpd international shipping stylish chairs for living room international investing stylish t shirts what do i need to do to start a business why is effective communication important in health and social care bad communication skills stylish photo frame
