The XL-380 is a supersonic busines jet airplane, Mach = 2.5
KSP version sorta perfected.
As pleasant a sihouette as a Blackbird, but better!
So far I haven't been able to get this beauty working...
Nice, sleek, solid design. The pens are really working out for you, too!
I see Blackbird, Learjet, Concorde... well done!
flying better than a G6!
I smell another potential paper model. Another nice design, XHS
