Create an air breathing plane that can sustain over 800 m/s of leval flight while flying at least 20 km for at least 10 minutes. This must use ONLY the stock air-breathing engines without any thrust assistance including but not limited to taking off. And thirdly the plane mus take off the runway and cannot take off on the launch pad. You MAY use mods for wings and anything other than engines. Ranking... 1st...... 2nd..... 3rd..... 4th..... 5th..... 6th..... 7th..... 8th..... 9th..... 10th..... Good luck kerbonauts! (Please show some kind of proof, Video will be appreciated but a series of pictures showing the time, altitude, and speed will suffice.
