Look at the bright side, at least flights today are still as fast as 60 years ago.
For trains, you would be hard pressed to find a route that is not significantly slower today than 60 years ago.

It took 64 years (until 1997) to again reach the 1933 speed of the Flying Hamburger [0] - 138 minutes from Hamburg to Berlin. Trains today need about 115 minutes.
Your gas car's maximally efficient speed is about 35 mph.
Modern jets are built to fly slightly slower than early jetliners, both in normal operation and at top speed. The reason is fuel economy, but the difference is real.
I don't understand the need for all the smoke and din in this argument thread. Old passenger jets flew a little faster than modern ones and that's okay!
That’s my point. It. Is. Not. A. Measurement. Of. Speed.
It's dependent on the speed of sound, which is only dependent on temperature, not specifically altitude contrary to popular belief.
Why is everyone trying to ackshewally this? The stat's are publicly available. Aircraft are optimized for a particular speed range and that impacts the designed cruising speed as well as Vs and VNE.
