Oh,yes. We do have a big red button. In fact there are several of them around the room. Alas, it shuts down the hydraulic pump, killing power to not just one test, but to ALL of them...the entire lab: eight load frames and nine bedplates. Only in a worst-case-scenario would I want to push that button. To save a coworker, yes! More often I have pressing need to shut down a single test rig to save a test sample, a one-of-a-kind prototype (or the instruments attached to it) from being destroyed.
