use ten pencils per flight so they don't have to be sharpened? that still saves millions of dollars.
valid to a point, but pencil points dont last long (we use em in medical a lot and we always need to sharpen them, one page of writing and its more or less useless) and if you break the tip, what then. send up 100s?
but i do see your point. not sure if theres more to it than i know.
