I would have to dig more deeply into it. But I am familiar with the SR-71, and it's major problems weren't with the size of the sonic boom. The principal problem is heat from friction. That causes the fuselage plates to expand. They solved that at Skunk Works by making the plates loose-fitting, but then the craft leaked fuel like a sieve. But at supersonic speeds, the plates expanded and it sealed right up.
It will be interesting if they have solved that problem in a way that doesn't require refueling immediately after take-off. - 1pg----------------------
Thanks 1pg, that is interesting about the SR-71. I have never heard about that problem before.
Here is another article on traveling at supersonic speeds that I found quite interesting and you may too.
https://a-z-animals.com/blog/how-fast-is-mach-9/Faster than the speed of sound, Mach 9 travel is similar to a spacecraft returning to Earth through the atmosphere. It's fast, it's hot, and it's fascinating to learn more about how quickly humans can will their inventions to travel.
Discover more about Mach 9: how fast it is, if humans can travel at that speed, and which aircraft, if any, can travel at that speed.
