It very much reminds me of a Blocked Toilet on a QUANTAS Plane. The Pilot insisted that the Tech blow out the loo on the opposite side to clear the blockage so the plane could return to service immediately.
While the Pilot was supervising at the Blocked end the apprentice blew out the other loo and covered the Pilot and everything on that side of the aircraft with the waste matter that was causing the blockage and a lot of the contents of the Sullage Tank.
Needless to say the Pilot didn't take the plane back to service and needed a change of clothes. Took about 3 weeks to clean the plane out and the smell to go away.
