Oschon-E clipped through the terrain at 11.8km and exploded, so I am going to call that the highest point on Eve(within ~30 meters, it's pretty flat up there). Also found a spot for a new resort. Come for the views, stay because we don't have a rocket big enough to get into orbit! EDIT: Something I just noticed; the indicator on the atmosphere bar in the first pic is just a little bit to the left. It would seem that the atmospheric density at the top of that mountain is about Kerbin-normal. Edit2: After several attempts, I can conclude that terrain on Eve breaks at about 11800m and you pass right through. Can anyone else confirm?
