Reminds me of this
Saw a program where one of the engineers was describing how they came to choose this shape, as the earlier designs and models all made a big boom when passing through tunnels at speed, and if the driver went too fast, they’d shatter windows with a really loud one.
They understood it was ripples, and one noticed that kingfishers were able to enter still water with barely a splash or ripple. So the design of the front of the train is the same as a kingfisher’s head… and so, noticeably is this plane.
