What it was really like to fly on Concorde
https://edition.cnn.com/travel/article/concorde-flying-what-was-it-like/index.html
When I saw Concorde on TV, I thought that there would be more and more aircrafts fly as fast as or faster than Concorde.
But, in fact, it hasn't yet happened. Furthermore, all of the Concordes ended their service.
I guess that's because research on aircrafts has recently focuses on safety rather than speed.
In my opinion, it's better tendency, considering what happened to transportations looking down on safety and focusing on speed-up.
