25 years ago...
...I was a passenger on a commuter airline flight from EVV to STL. The flight had been delayed for about :45 minutes. So another passenger and I decided to have a couple of quick beers while waiting. We had every intention of taking a leak before departure of the :50 minute flight.
Suddenly the flight was called for an immediate departure....no time for a pee. O.K. I thought: it is only a :50 minute flight. I knew that their Sweringer Metroliner did not have a bathroom: but it will be alright.
Well as luck would have it we went into a holding pattern approaching STL about the time that I was feeling some discomfort. After :20 miserable minutes in the hold we were released for the approach. My drinking buddy said that he was really suffering as was I. About 2 minutes before touchdown I was in such pain that I was becoming sick at my stomach and felt that my bladder would burst.
The flight was full and there was no privacy but I took out a sick sack opened it and held it close. There was no way that I was going to piss in my pants. We touched down and headed for the gate...the agony was something akin to childbirth. Gritting my teeth I knew that we would be at the gate in just a minute and perhaps I could hold out that long.
Lo and behold...the gate was occupied and the captain announced that we would be parking off gate, shutting the engines down and would have to wait for fifteen or more minutes. That was all my partner and I could stand. As soon as the captain shut down the engines I went forward, showed him my airline I.D. and said that I had to get off and piss on the ramp. I lied about my drinking buddy and said that he was with my airline also and in the same condition as me.
The captain stated that he could not let me out of the airplane and on to the ramp....even if it was after dark. "Fine" I said. "We are going to unzip our pants right here and piss in these sick sacks right in front of your passengers...we have no choice."
With that the copilot got out of his seat and let the passenger stairs down. My buddy and I ran around the nose and standing close to the aircraft.... proceeded to wash down the ramp. Never in my life have I felt such relief. While we relieved ourselves I had visions of myself standing at attention in the Chief Pilot's office come Monday morning. Shortly we reboarded and soon taxied to the gate. Not a word was ever said....and I never heard from the Chief Pilot.

p.s. I have carried ziplock bags in my personal airplanes for 25 years. Ever since I tried unsuccessfully to piss out the side window of a Citabria in flight.
