I was hoping we could keep that joke going... oh well. Last night I remembered how important electrostatic charge efficiency is when flying tourists in LKO, using a Stayputnik robo pod, and not having unlocked the solar panel branch of the science tree. Had just enough power left to get them into the very top of the atmosphere (ie 69,950m). Aerobraked enough to bring them back down to the surface after about 20 orbits, so I thought I'd tick off a few more contracts on the Mun in the meantime. Coming back to my now descending orbital tourer, it turns out that parachute deployment also requires electrostatic charge. Luckily for the tourists, I don't think they felt anything when they flew into the side of a mountain at 300m/s.
