In the race to produce a working design 35 years ago, Lockheed lost out to MD, with the DC10. What with Lockheed's fusing (which MD considered, but discarded), the poorly designed cargo door (which blew out a number of times, collapsing the floor onto the flight controls, resulting in bent hulls & bodies) of the DC10 (Lockheed had an inward opening door, which was inherently safer), and many other items, Lockheed was a much superior design, but a financial disaster. Public gets what it pays for!
