That sounds like the Skyfox, which was acquired by Boeing in the mid-80s. You’re really underselling the appeal, too, it looked sexy as hell. It’s like an A-10 with aerodynamics actually placed into consideration.
Also, for the sake of nerds that like numbers, I’ve included an addendum that breaks down what I could find about the Shooting Stars in Bolivian service. Either way, it was a fun little write up to do and I appreciate the reaction. I may do more in the future if I can find similar aircraft that find themselves a niche and just kept going. Let’s call it “Coal Burners.”
