Question

Why does an air passenger prefer a ball pen to a fountain pen ?​

Answer 1

Answer:

fountain pen basically ink pen leaks too much if there is a pressure diff

when you are at a certain height the pressure starts decreasing so the ink also starts flowing

in ball point pen the effect is very low because the nib of pen is closed with a ball which rolls and displace ink on paper

in ink pen the ink is directly displaced on paper
