I know I always do, the cockpit is a horror story afterwards, not to mention my flight suit, the cushions soaked, yech. We put extra water drains in the fabric below the cockpit but it hardly helps. Plus.. the wind whips it around so we always share.
Actually I got queasy and decided I didn't want the big farmer's breakfast I just ate one day as we were flying below low cloud deck.. I hastily folded the map into a container, you can imagine how well that went, then jettisoned that over the side. There were bits of potato and whatnot swirling around in the turbulence in the cockpit. Whee.
My crowning achievement is farting in the front cockpit while we're cruising at 75 - 5 seconds later over the intercom.. "OMG did you just fart?!!"..
open cockpit, who'd a stunk, er, thunk it?
