Dream of Flight
• In 14th century late Ming Dynasty, a Chinese officer named Wang Hu made first human flight with 47 manmade fireworks on his back and 2 big kites on each hand. Although he did not succeed, the concept and creation were praised by the western scientists.
• A crater on the back side of the moon was named “Wang Hu” in memory of his extraordinary contribution when U.S. astronauts landed on the moon in 1986.
