Yay! My first post ever! And my first completed challenge ever! With a few attempts I managed 24:19 I hope drop tanks and vertical launch are ok. I ran out of fuel in my previous attempts, even though I kept the throttle a little down. So I used a droptank for launch and getting to cruising altitude. I dropped the tank when it was about 2/3 full. The fuel ran out just before landing, I could use full throttle the whole time. Outrunning the sun. I kept the altitude at around 15 km until I was about 40 km away from KSC2 Objective complete! Lost the engine on touchdown but managed a 'safe' landing.
