This is one of those "I have a friend" stories - but never the less it is true...and it was indeed a friend who did it. On a 3 hour nav flight last christmas my flyingbuddy (who has a bladder the size of a shotglass) desided it was time to take care of business.
The idea was quite brilliant - climb in the back of the C172, go in the fuel strainer and then poor it out the window. After a few moments of relief I opened the window on my side (right side) after which I heard a scream from the back. Aparently he had put the full fuel strainer into the airflow and the air had now lifted the yellow liquid out of the strainer and sent it for his face.
The unexpected but very eventfull happening was of course caught on photo (after the fact) and if it hadn't been for the autopilot I'm sure keeping heading and altitude would have posed a problem for the minutes to follow. I've never laughed so hard in an airplane before - I guess simple humor is the best after all
