I'm not really sure that people should read that much into that, Aboulafia said.

“我不确定人们是否应该对此进行深入研究。”

However, Aboulafia said it should not be forgotten that for many years, the 747 had a major influence on the development of the airline industry.

然而，阿布拉菲亚表示，不应忘记，多年来，波音747对航空业的发展产生了重大影响。

It's also important to remember that a plane maybe 20 years old, but its engines and other major systems could have been recently manufactured or upgraded, said Aboulafia.

同时，记住一架飞机可能使用了20年，但它的引擎和其它主要部件可能最近缓过或升级过，这也很重要，Aboulafia如是说。
