Nothing is worse than being 2.5 hrs from land and out of piddle packs.
Plan was to drink a soda and try and hand fly(knee fly?)(no autopilot) while trying to pee into the soda can(that's why we fly with gloves). Then have to wonder how long it would take for the soda to go through me with no place to 'store' it.
Luckily the 'flow' ceased.
Squadron mate has 3,000+ hrs single seat time. Multiple 6-10+ hr sorties/deployments. Career piddle pack use? Zero.
