  • A few years ago I was hiking in the middle of fucking nowhere, Utah, just enjoying the red rocks and seclusion, when an F18 rocketed directly above the slot canyon I was meandering through, banking hard to follow the general direction of the canyon and utterly frying my tympanic membranes for the next few tens of minutes.

    I’m sure the military hardware fetishists would say I missed an opportunity for some kind of iconic photo of a fighter jet zooming through a frame of sandstone but all I could think about was how hard my ears were ringing and how disruptive that bullshit must be to literally all hearing wildlife.

    I was maybe 100 feet below the top of the canyon and the jet couldn’t have been more than 500 feet above that.

    This is all to say that if commercial aviation starts getting loud in places where I try to enjoy the nature I too will likely lose it


  • The question then becomes how much people are prepared to pay for 50% shorter flights, and how much the cost of supersonic flight has been reduced by improved technology.

    My main questions center on how much extra fuel is required to provide all that additional energy? Idk enough about fluid mechanics to answer this on my own: how much more energy does it take to accelerate from mach 1.1 to mach 1.2 vs mach 0.9 to mach 1.1?
