In the skunk works of $major engine manufacturer, and you hear an engine on the other side of the firewall go south, it sort of alters the trajectory of your own emissions.

the test bank close to the crappers is where they run up the fuel-gas powered engines- big ones, over 80 liter displacement and over 1500 horsepower- made to run on methane, natural gas, propane, whatever. The test cells look like big garden sheds wrapped in layers of nomex and Kevlar. The “Sheds” themselves are made of continuously welded plate steel, some of it several inches thick. The inside of several of them look as though they were chewed on by some huge and nasty creature.

Yep, sitting on the throne and hearing that go pear shaped almost literally on the other side of the wall, well, I will be shitting rotini for another couple of days, I think.
