That day they became the first people to demonstrate sustained flight of a heavier - than - air machine under the complete control of the pilot 他们在那天也率先成为完全掌控这架比空气还重的机器而持续飞行的人。
The first successful sustained powered flights in a heavier - than - air machine were made here by wilbur and orville wright on december 17 , 1903 1903年12月17日,莱特兄弟第一次用比空气重的飞行器进行了有动力的持续飞行。
Bats are the only mammals capable of sustained flight , and , unlike birds , they can fly at relatively low speed with extreme maneuverability 蝙蝠是唯一能够持续飞行的哺乳动物,与鸟类不同的是,它们飞行速度较低,但极具机动性
