Basically yes. Ukraine has a big problem with soviet commanders who waste lives needlessly. The post Soviet younger commanders have much better reputations and use that to recruit, ie 'you can join my unit and won't be conscripted'. The popular and successful units grow and split into sub units. This way they dont have to fire the unpopular soviet era but politically connected commanders, they just slowly lose relevance.

That's only possible under specific climatic conditions where there's separate temperature/pressure layers. Which is why they asked to repeal the ban on supersonic flight over populated areas. If they actually thought it wouldn't make noise they wouldn't be asking for the rule to be changed.

Overland private supersonic travel should not happen, it would just be a massive unpriced negative externality.

The lower the plane flies the fewer people end up hearing the boom. The denser air also requires an absurd amount of fuel to fly through. Commercially uneconomical. Even the military only uses low level supersonic for a last dash to the target.
