I've been sending quite a few planes to Eve, due to the thick atmo they work rather well with minimal fuel consumption. . . . as has been said . . no jets unfortunately. have some pics: In fact flight is SO easy that I have been wondering if an ion powered glider will work . . I have made one that can take off and fly (slowly) on Kerbin under Ion power only. . . not enough solar panels to make that sustainable. . . once the 20,000 units of electric charge it carries are out it will have to land and deploy some it XL arrays to recharge. No pics of that one but I have another glider on route to Eve at the mo. This one works so well its actually really hard to land. . . . it WANTS to be in the air!
