Some small progress in aviation

In 1920, ....

Early passenger flights could be severely hampered by low cloud and headwinds. If the cloud base was at 200 feet they had to fly at 150 feet, sometimes following railway lines along valleys for navigation. Cross Channel flights might be at an altitude as low as 40 feet. Headinds could slow the plane up so much it was overtaken by buses on the ground.

In 1979......

20/4/1979, The last Concorde to be built made its maiden flight. Only 16 of the aircraft were ever built; they were too noisy. Even the lawyer hired to secure landing rights publically admitted “Concorde is noisy as hell”.

13/1/1979, Concorde began a regular service between Washington DC and Dallas airports.

If the space industry progresses as fast, we will be seeing regular passenger flights to the Moonby 2030. Somehow, I doubt it though......
