It's a 1/3 scale prototype of their passenger jet.

  It's not a "scale" prototype since it has a different configuration from the passenger jet: https://aviationvoice.com/wp-content/uploads/2016/11/Boom-Technology-Unveils-Supersonic-Demonstrator-1200x900.jpg https://aviationvoice.com/wp-content/uploads/2016/11/Boom-Te... It'd be scale if it was the exact aircraft except every linear dimension was shrunk down. But having a different number of windows, different inlets etc. makes it a smaller concept demonstrator.

    It can still be 1/3rd of the scale, even if it's not a "scale model"

      Not when the configuration is drastically different. "Scale" has a very specific meaning in engineering. It's like saying a motorcycle is a 1/3 scale version of a car just because it uses the same motor. It still demonstrates that the heart of the vehicle works, but it's not a scaled version of it. Here's an actual scale model in aerospace: https://www.youtube.com/watch?v=GHz2B_4g2tM https://www.youtube.com/watch?v=GHz2B_4g2tM

        A motorcycle is not a "1/3 scale version" of a car, but it is "1/3 the scale" of a car (assuming a car is roughly 3 times larger). Scale is not just used in engineering. For example a zoo might have a scale comparison of different animals.
