Wow, that guy does win. I can\'t even get a space plane to fly under the best of situations, let alone with the pilot outside of the craft steering by jumping on the wings. A problem appears: bomb got stuck between the engines Jeb saves the day by ramming it with his head! Unfortunately Jeb slipped off the ladder at the reentry. He is heartbroken about missed opportunity of riding a bomb. Second attempt: I can see my home Kerbal Space center from here! It\'s showtime! Surprisingly enough, one of the fuselages survived the impact. This time the 'pilot' stayed on the bomb till the very end. Well done sir! Just like the movie! =D

Quite simple. Create a rocket and launch it into orbit (or a suborbital trajectory, doesn\'t matter as long as you leave the atmosphere). Then, boost in such a way so that your trajectory will once again take you into the atmosphere. Send out at least one Kerbonaut on an EVA so that the craft is uncontrolled (you can do this any time before you craft re-enters the atmosphere). To complete this challenge, your kerbonaut must be outside the rocket throughout the entire aerobraking procedure. Scoring (for people who are interested in that sort of thing) will be determined by the minimum altitude reached while the kerbonaut is riding the rocket. Note: in case if I did not make this clear, no adjusting your trajectory once you have entered the atmosphere. Go go go! =D

1. let's say you want to get from a circular orbit of 100km (semi major axis of 700km due to radius of Kearth) to a circular orbit of 7800km (700km * 12 ratio of semi major axis = 8400km, subtract 600km to account for radius of Kearth) regardless of what I set the turnover altitude to, the delta v value is dramatically lower for the Hohmann transfer than for the bi-elliptical transfer when I enter these numbers into the calculator. From this we can determine that either wikipedia is incorrect, or there is some small error in the calculator 2. Due to my inability to speak words good, I uploaded my next point in picture form. It pretty much outlines the reasons why I started to suspect that there was something wrong with the calculator. This is what I tried (and obviously failed) to explain in my first post.... Contrary to how I know I probably sound, I'm trying to be helpful =P edit: I acknowledge the fact that I would be more helpful if I knew what was wrong rather than just the fact that there is something wrong...

oh no, I know what bi-elliptic transfers do. it's just that I couldn't find a set of numbers to put into the calculator that gave that result, and I put forward a theory as to why that was the case...

Hey, I've been using your calculator recently, and I think there might be an error in the part that calculates bi-elliptical transfer orbits. I was fiddling around with some numbers trying to find a set of altitudes that resulted in a bi transfer with a lower delta v than an equal hohmann transfer when I realized something. with a lower orbit of 100km and an upper orbit of 1000km, the delta v needed for the transfer orbit injection in a hohmann transfer orbit is about 403 m/s. However, in a bi-elliptic transfer orbit with a lower orbit of 100km, a turnover altitude of 1000km, and a higher orbit of 900km the Transfer Orbit injection required a delta v of about 966 m/s. From what I understand, because both of these injection orbits start at the same altitude and end at the same altitude, the delta v should be the same... I could be misinterpreting something, but I think that it is likely that something is wrong given that there is no altitude change that I could find that makes the bi transfer cheaper.
