years ago in my father's company, an electrician went to measure 400V power with a multimeter, but he used the same lead on both sides, shortening a high power 400v line. he was not wearing gloves and he got burned so badly he had to stay off work for months.
high power electricity is dangerous stuff
Ckaminski, SpaceX has had its share of failures and if you count failed landings as failures the success rate is pretty bad
regarding the very impressive landing of the first stage, many experts are not so sure it makes sense at all, the penalization of having to use about 7% of the fuel for landing is pretty large as the last fuel is what generates the largest delta V, and the additional weight of the landing gear reduces the payload
i am not very convinced about the idea of reusability of launch equipment, so far the savings promised have failed to materialize, and lets not forget how the space shuttle turned up.
EM likes to come up with unorthodox, exotic technical solutions, none of which seems to have ever produced a cent of profit.
