I spoke to a start-up founder convinced he can build a supersonic jet powered by green aviation fuel.

我与一位初创公司创始人交谈，他确信他可以制造一架由绿色航空燃料提供动力的超音速喷气式飞机。

But prices of similar jet powered wings have reportedly cost around $150,000, and that would take some serious " bling" and " wing" up quite a tab for a " wing suit" that might " wing" you a " fascinatwing" view.

但据报道，类似的喷气动力机翼的价格约为15万美元，也就是说要花大价钱才能买到这副喷气动力机翼，从而为你赢得众人惊异的目光。
