20210107 多佛尔白崖 必应壁纸

多佛尔白崖 多佛尔白崖 所有人都是凭感觉飞行的，但如果完全没有感觉呢?这就是让-皮埃尔·布兰查德和约翰·杰弗里斯所面临的困境，他们在1785年1月7日第一次空中穿越英吉利海峡，在这片白垩悬崖上创造了历史。当他们的氢气球因超载而下降时，他两人把所有能装的东西都扔到了海里，包括裤子。空手抵达法国时，毫无疑问，饱受严寒的飞行员仍然受到了热烈的欢迎。世界闻名的多佛尔白崖是英国的象征，高350英尺，横跨布兰查德和杰弗里斯横渡的海峡。白色的白垩和灰黑色的燧石条纹在地质学上与法国一侧较短的悬崖相吻合——这证明远在灵长类动物有飞行的想法之前，大陆桥就已经存在了。当然，即使是在海浪上翱翔也有点过时了，因为现在你可以从海底穿过海峡，而海底隧道的入口就在海岸。

原文:

We all fly by the seat of our pants now and then, but how about flying with no pants at all? That was the plight of Jean-Pierre Blanchard and John Jeffries, who on January 7, 1785, made history over these chalk cliffs with the first aerial crossing of the English Channel. When their hydrogen-filled balloon dropped altitude due to overloading, the two tossed all the cargo they could into the drink below, britches included. Reaching France in their underpants, the undoubtedly chilly pilots still received a warm welcome.Known worldwide as an emblem of England, the White Cliffs of Dover rise 350 feet over the strait where Blanchard and Jeffries made their crossing. The white chalk and gray-black streaks of flint match geologically with shorter cliffs on the French side—evidence of a land bridge that existed long before we primates got the notion to fly. Of course, even soaring over the waves is a bit outmoded now that you can zip under them in the Channel Tunnel, which has its entrance just down the coast.
