Guilty as well! I'd like to add my own: After crashing a Mun lander (see "Altitude", above), I sent out a remote controlled rescue capsule. I got it into transfer orbit and warp. When it gets to the Mun, there is no power left, which rather surprised me as I used the exact same rocket mark the succesfully had carried the original lander. Took a while to realise that remotes use electric charge constantly....
