Analysis of information sources in references of the Wikipedia article "Buck Rogers" in English language version.
Only four entities have launched a space capsule into orbit and successfully brought it back: the United States, Russia, China, and Elon Musk. This Buck Rogers dream started years ago
The DC-X launched vertically, hovered in mid-air at 150 feet, and began to move sideways at a dogtrot. After traveling 350 feet, the onboard global-positioning satellite unit indicated that the DC-X was directly over its landing point. The spacecraft stopped mid-air again and, as the engines throttled back, began its successful vertical landing. Just like Buck Rogers.
