The Red Arrows are the Royal Air Force aerobatic display team. The trails of coloured smoke they leave in the sky are made by releasing diesel into the exhaust, which oxidises and leaves a trail of smoke. In this photo, dyes have been added to produce a blue and red colour.
红箭是英国皇家空军的空中特技飞行表演队。飞机在空中飞过时会留下一缕缕有颜色的烟雾。这些烟雾是飞机从排气管释放柴油，然后通过氧化过程而形成的。在这张照片中，柴油里加入了红色和蓝色的染料，所以喷出的烟雾有了颜色。
Daniel is such a high-flyer. He's only 31 years old and he's already the financial director of the company.
My brother is a high-flying businessman and travels all over the world.
请注意
另外有一个短语 high-flown, 虽然拼写很像 high-flyer，但含义不一样，意思是夸张的，华而不实的。
He tried to seduce Katherine with high-flown language, but she wasn't impressed.
