            I agree. But sadly, a lot of progress is driven buy conflict as well.

            Unless a nation is under an existential threat there is little motivation to invest in progress.

    Guys, check out the cockpit.

    I know technology is wildly advanced and he probably has a 360 view now, but other than test pilots, who are you going to get to fly a plane that lacks a forward view?

      One of the material issues with supersonic is friction heat buildup. Probably can’t have a front windshield at that speed.

        The heat is from compression, not friction. And besides that, this thing is only flying at mach 1.5, there are TONS of aircraft that fly at those speeds (and much faster) with windshields.

        The reason it doesn’t have a front windshield is because the change in shape of the aircraft at the windshield, to be more vertical, was disrupting their method of reducing the sonic boom. The aircraft needs the shape it has, so a windshield would have to be like 20 feet long to offer any forward visibility.

          Yeah something like that. Welding is absolutely something that requires skill and talent.

          I have a electromechanical engineering degree myself, at some point during my education we had some labs where we did basic welding, milling, lathing and whatnot. The intention was not to become experts at it, but to get notions of what it entails. I quickly understood that theoretical understanding and hands-on experience are entirely different things, and require an entirely different skillset.

        Even regular planes have negative effects on the neighborhoods they take off and land over. This is definitely going to be worse.

          Yeah, apparently we do…

          The problem with Sonic booms isn’t that you notice them, it’s fine to notice the sound of a vehicle traveling overhead. The problem is that the sound from previous supersonic jets has shattered windows all along the flight path, ruptured eardrums and caused moderate hearing loss.That is a problem…

          If this instead sounds like a car door closing, I’d call that significantly quieter.

      Considering that splitting supersonic shockwaves in the air is kind of analogous to splitting the water when plunge-diving for fish (which at least some pterosaurids are hypothesized to have done), that makes sense.

          In commercial airliners, nearly the entire flight is now closely monitored and controlled by redundant computer systems. And the pilots rarely use the front window, they mostly fly by instrument.

          Cameras as the cockpit windows aren’t really that crazy at this point. Really glass cockpits are a formality.

            Glass cockpit is a specific term for flight decks that have replaced analog gauges with digital gauges and screens.

            Pilots use the windows all of the time. They use it to look for traffic and for vfr approaches.

            It’s really not, flying without looking out the window is very common especially for NASA and the USAF.

            Absolutely, in fact it’s not just nasa or military, almost everyone does that. You need to prove that you can fly without looking out the window to get your “instrument rating” and be legally allowed to fly at night. Every instrument flight rated pilot can do it (a majority of pilots). However, airports are lit up with lights, so even at night or in fog, you can see the runway as you’re landing. If you have no windows, you can’t do that, you’ll need someone to guide you down.

            That’s not my concern, the issue is a lack of redundancy. If the computers crash or if the vehicle loses power your suddenly have no windows. From a design perspective, it’s a risky choice. Not insurmountable, but it’s a potential problem point. It’s a choice that adds an additional critical single point of failure.

              lack of redundancy is a concern, but the same was said for fly by wire cutting the physical link between stick and controls. fly by wire is ubiquitous now, can be made very very safe, and is a net gain for aviation in general.

              not having a window is obviously a bigger challenge, but its still a solvable problem.

              Yeah but looking out the window as your plane crashes isn’t going to change the fiery death that a system shutdown on a modern airliner will inevitably bring.

              I get what you’re saying but a window is a structural trade off too, they’ve obviously done the testing and determined it’s a sensible design choice

                Simply not true.

                There are redundant systems for everything on aircraft. You can certainly control the plane without the computers working, and without any instruments working. You can generally control the plane even without power because of redundant hydraulic systems.

                Thinking computers are necessary to do anything is wrong when it comes to aircraft.

                And obviously the choice to eliminate the windows is entirely a structural design, that’s where you see the benefits, which I’m sure are quite real.
