:The Sänger Amerika Bomber (or Orbital Bomber, Antipodal Bomber or Atmosphere Skipper) was designed for supersonic, stratospheric flight. The fuselage was flattened, which helped create lift and the wings were short and wedge shaped. There was a horizontal tail surface located at the extreme aft end of the fuselage, which had a small fin on each end. The fuel was carried in two large tanks, one on each side of the fuselage, running from the wings aft. Oxygen tanks were located one on each side of the fuselage, located forward of the wings. There was a huge rocket engine of 100 tons thrust mounted in the fuselage rear, and was flanked by two auxiliary rocket engines. The pilot sat in a pressurized cockpit in the forward fuselage, and a tricycle undercarriage was fitted for a gliding landing. A central bomb bay held one 3629 kg (8000 lb) free-falling bomb, and no defensive armament was fitted. The empty weight was to be approximately 9979 kg (22000 lbs). An interesting flight profile was envisioned for the "Silverbird". It was to be propelled down a 3 km ( mile) long monorail track by a rocket-powered sled that developed a 600 ton thrust for 11 seconds (please see diagram below). After taking off at a 30 degree angle and reaching an altitude of km (5100'), a speed of 1850 km/h (1149 mph) would be reached. At this point, the main rocket engine would be fired for 8 minutes and burn 90 tons of fuel to propel the "Silverbird" to a maximum speed of 22100 km/h (13724 mph) and an altitude of over 145 km (90 miles), although some sources list the maximum altitude reached as 280 km (174 miles). As the aircraft accelerated and descended under the pull of gravity, it would then hit the denser air at about 40 km (25 miles) and 'skip' back up as a stone does when skipped along water This also had the added benefit of cooling the aircraft after the intense frictional heating encountered when the denser air was reached. The skips would gradually be decreased until the aircraft would glide back to a normal landing using its conventional tricycle landing gear, after covering approximately 23500 km (14594 miles).
