The skies of Oklahoma City roared for six months in 1964 as military aircraft intentionally rattled the population below with a daily barrage of thunderous sonic booms. It was a controversial test — the consequences of which have lingered to this day.
Two approaches in the works could revolutionize air travel by making future supersonic passenger planes compliant with the FAA’s new noise rules: Colorado-based company Boom Supersonic, which is specifically mentioned in the FAA proposal, plans to use physics to prevent sonic booms from ever reaching the ground, regardless of plane design. NASA, on the other hand, is flying an experimental plane called X-59 that is specifically designed to reduce the intensity of the boom.
You dont see an immediate usecase for faster travel and point out its cost as if costs do not come down over time.
Who needs a flatter screen, a few people with enough money to make freeing up a foot and a half behind their tv a worthwile expense isnt really a problem worth solving.
Your second point is amazing, irrefutable.
