Hi all, thanks for taking a look at my latest craft! The Bell X-1 was the first aircraft to break the speed of sound, on October 14, 1947. The Bell X-1 is carried to altitude by a B-29 Superfortress, then dropped to accelerate to a bit over mach 1. Enough history, let's have some pictures: How to fly: Take off. Turn 90 degrees to the left. Climb to 3000m, this will take a while. Browse the forums for a bit. Drop the bell X-1. Climb at a 20 degree angle to 4000m, then level off and go supersonic. 333m/s is about right. Land. Now, they both can land, separately. I haven't got the B-29 and the X-1 landed on the same flight. Note: This thing loves to run into watermodule.slider.collider, or have bits of it randomly overheat. Warranty voided by visiting forum.kerbalspaceprogram.com. Enjoy!
