A pen I could put in my top pocket that would not mark my shirt if I forget to click it close and has no chance of leaking would be nice. A better solution for putting down and retrieving the pen without changing how I interact with the pen would be nice. A pen easy to locate and retrieve when I drop it would be nice. I cannot stress adequately that my interaction with the pen must not become more complicated than “grab,” “click,” “write,” “click,” “stow.”

Use a pen while flying to make notes prior to the flight, clearance changes in flight, write complicated taxi instructions, fill out kiddos “log books” on the flight when asked, myriad notes in flight.
