No, I did not design fighter jets. While working in the aerospace industry, I had the opportunity to work on many programs for GE Aircraft Engines and McDonald Douglas Missle Systems. The company I worked for was one of only two companies in the country that could super-plastic-form titanium parts--a kind of duopoly. The most significant project I designed on was for a small titanium duct that would allow fuel to vent to the exterior of the plane should the engine develop a fuel leak. This was important, as the jet was the F-16, which only had one engine. If it should develop a leak, you could not shut it down and limp home on the other engine--you ejected before it went up in a ball of flames.
