It may have been a bit much to make the red shirts write their own names on the MK I's. Just double check the seals on the shuttle door next time you are in it. Just saying.
Nah, I'm not too worried. Shuttles don't last long enough on my ship to be sabotaged. Seriously, I have Katherine Janeway's niece as a my shuttle officer. That woman loses more shuttles than I can count -- attacked by random aliens, crashed on planets (women drivers, amirite?), abandoned for no explicable reason, random plot holes, etc. Must be a family trait. I had to switch to an Escort Carrier just to keep enough shuttles in stock.
