a pen that "writes
In zero дгауКу,
down" while
the Russians used а
pencil instead
Pencils are flammable and NASA
wanted to avoid carrying
anything flammable on board
after the Apollo 1 fire. The Fisher
Pen Company, learned about this
challenge and made a space pen
which was used NASA. After
this,the Russians approached the
Company and bought the same
space pen. Pressurised pens
have been used ever since
both American and Russian
manned space flights.
