This "amerika bomber" was an idea to use the flying wing design with 6 yes 6 turbojet engines to give it a supersonic speed caperbility it would have a crew of 3 and fligh at high altitude to drop either conventional or nuclear payloads on America (this was designed in the 40s!) overall you have to respect the people who could design planes like this 60 years ago! Compare this to a glouster meteor! We were so far behind on tech! But anyway the project was scrapped as on the last months of ww2 German supply lines were cut so they never built it (it's a good job they didn't) anyway first accelerate on the runway to 100mph when you hit 100mph press 1 then you will take off at the end of the runway and retract landing gear when you are at 500mph press 2 be careful this isn't that strong so if it goes over 800mph it will break and if you try and roll at 750+ the wings will do a little dance and the plane will explode :)
