Well, I did it. Although I finished this without looking at the rules, so I suppose my submission is void. I used the B9 pack for my plane, as well as FAR. Oh, well also, I suppose I used drop tanks too. Oh, and the lazor mod simply for navigation purposes. However, it was an absolutely spectacular flight, a polar circumnavigation cruising between 12-17km at 1200m/s for less than an hour, and I was back at KSC. However, the scary part was landing, considering I had never had a successful landing with the aircraft I used, so I prepared myself for several go-arounds. On the first run, I came in a little high and fast, but successfully touched down going .5+/- mach and hit the brakes. Did I mention it was at night? Well, as luck would have it my front wheel LITERALLY stopped between the landing lights on the runway, (I landed backwards, because I just had to do a flyby and buzz the tower following such an epic journey, the first of its sort for me). http://i.imgur.com/VMbr2w6.png' alt='VMbr2w6.png'> Literally right where I came to a stop, an hour and 5 minutes in with 1100 litres of liquid fuel left. Unfortunately, as I tried to EVA my pilot to plant a flag in honor of this momentous occasion, CRASH BANG GRIND, my game crashed. And regardless, I know this doesn't even come close to the rules for this challenge, I'm still happy for such a prolonged and detailed mission being completed successfully, and without even leaving the atmosphere.
