Superb in every engineering sense, due in part to many Brits in design team 🙂 . Vendors who had come second on 747/DC-10. Brick s-house, thus uneconomic. Junked ‘cos Lockheed abandoned Product Devt. in 1982, leaving MDC to take MD11, and gave less help to Marshall’s and Tradewinds’ freight conversions than MDC did to OAV DC-10F/FedEx MD10 (no FE). Spares now sourced from part-outs, so slow, scarce. Pax love it…if operators attend to its foibles.
