Slightly off topic, but it always tickled me when stuff on Star Trek and other sci fi series would break down with sparks and flames shooting from control panels.
Then the crew take equipment covers off and poke about inside the equipment, pulling boards and stuff out of the kit and saying things like "I'm afraid the neutron furtwangler has clunched the murkledrive cap'n!"
Medical engineering is just so easy by comparison. Casualty don't need engineering staff, because nothing there is travelling faster than sound or between galaxies !
