  • Well, you can control your airspeed and attitude in an airplane, solid rockets just make a ballistic arch and they only accelerate, they can’t maintain a speed.

    So if you want to test how air behaves in a particular regime, you can’t actually maintain that regime with a sounding rocket, so the best you can get is a snapshot.

    Honestly, if what they’re working on is dialing-in their computer models, the more precise data they can get, the better. It makes sense to maintain a speed for a minute, so you can get a really good running average on your measurements of air pressure, heating, drag, etc. They may want to conduct the same tests at different altitudes and airspeeds, and probably all in level flight. To control all those factors, that’s near impossible to do with a rocket.

    Again, I don’t know what they’re doing, what their actual plans are. I’m just saying there are absolutely plausible reasons to use this aircraft.





  • Sure, if it had any payload capacity. But it doesn’t.

    Getting a machine up to that speed is hard, real hard. The margins are extremely small. So the moment you start adding additional moving parts to it, opening payload bays, weapons release mechanisms, a few 400 lb missiles… And don’t forget, all those additional components also take up additional volume, higher volume means more air displacement, which means more drag. Higher volume also means the area of the airframe gets larger, that means additional mass.

    All of a sudden, that plane can’t hit mach 3 anymore and you don’t actually have an untouchable weapons delivery system anymore.

    This is probably why a combat version of the aircraft was abandoned, it doesn’t really make sense.







  • Ok, was surprised about that, so decided to look this up.

    It turns out this is correct, the expression does tend to use “lede” though “lead” is also occasionally used. You could call that occasional usage just people making a mistake, except for one thing… “Lede” is just an archaic English form of the word “lead” and they both mean “to guide”. So “burying the lead” is exactly the same statement as burying the lede", but with an archaic word replaced with the same modern word. So my question is, is that wrong?
