Today I fancied visiting the north pole for an arctic excursion. What I noticed on the way was, unless I angled quite sharply upwards, I\'d rapidly descend. Then, obviously, I\'d ascend up until the engines no longer had the atmospheric throughput they require and dip down to where they did, then go up, fall back down, etc. This strikes me as heavily inefficient, is there a better way? Maybe a more specific pitch using Mechjeb?
