Howard Hughes in the Spruce Goose. The ancestors of jumbo control systems were pioneered in this aircraft. What Hughes also discovered, to his suprise and fear, is the lifting body phenomenon of large airframes. O.k. it is an amphibious ship. There was an attempted water ditching by a jumbo some time ago by a hijacked liner. It unfortunately broke up. Just because something hasn't been done, doesn't mean it can't be. As to wire, forget it on many carriers. It looks like a garrot.
