First attempt was clumsy and I knew it early but I stupidly tried to save it. It was too steep and I boosted up and initially saved it. What I should have done is re-enter SC and start all over. I almost made it but I never fully regained a controllable descent and sploded. With a sizable amount of explo data I might add. Just stupidity on my part and I paid for it.
Round 2 was textbook. Easy really. Just enter at a shallow angle. Use maximum patience. Level your ship and never roll or pitch more than a few degrees. Do not use up or down thrusters because of the way that FA on works. Lower ship by cycling FA-off off-then-on. It’s a good idea to temporarily change the FA off control to the setting where it is only FA off while you are holding the button. Not at my computer atm so I cannot remember the exact setting, but it’s the opposite of toggle. Anyway cycle FA off momentarily to drop and let FA on stop your descent. When you get close to the ground lower landing gear and using yaw only find a landing spot. Touch down by cycling FA off very quickly and wait till stable before touchdown. ED cheats to allow any thrusters you have installed be able to overcome any gravity so that nobody gets stranded. But this is only true for your “up” and “forward” thrusters.
To lift off, use up thrusters with ship level and do not stop for any reason or you will crash. Keep increasing altitude till you are at a safe altitude. I waited till 10km. While continuing to thrust up, go to to full speed forward. After achieving full speed while thrusting up, pitch up, boost and slowly release thrusting up while continuing to boost. That should get you back to SC.
