I'd just shut down at my destination today when they were towing a nice, shiny Conquest out of the hangar. Two fellows in white shirts with shoulder stripes and black trousers boarded it. A few moments later I heard the unmistakable sound of a high pressure gas venting from its tank. Seems someone on board pulled the fire extinguisher bottle for one of the engines. Oops.
I went about my business, and as I was returning to the airport about an hour later the Conquest was just taxiing out, no doubt having had the extinguisher recharged. Wish I could have heard the flight deck CRM discussion about that episode.
