I've read the responses with interest, as I've always considered the L-1011 to be one of those vastly superior products that was beaten in the marketplace by a greatly inferior product (the DC-10) for various reasons. I like the currently-used slang for this phenomenon: to be "Betamaxed" (anyone who's seen a Beta videotape side-by-side with a VHS tape knows that the VHS format is inferior, yet it succeeded while Beta flopped). I guess one could also use terms like "Microsofted" or "Intel'ed" or "Honda'ed"with equal accuracy :-) >From what I've read, the L-1011 was indeed superior to the DC-10 in construction and certainly in terms of its field record since the VAST majority of the airframes produced are still flying today, though many are as freighters. One thing that hurt it, though, was that since it was solidly built (and thus a bit heavy) it had to be *shortened* to produce an extended range version (the L-1011 500) whereas the DC-10 was actually lengthened. This wasn't attractive to buyers. I've never heard anyone say it outright, so it may be wrong, but my gut feeling is that the L-1011 is designed to a completely different philosophy than the DC-10. Walking around and aboard a -1011, one gets an impression of tremendous solidity. It looks like its built to LAST, with many features seemingly over-designed and thus a bit bulky compared to a DC-10. This would tend to be borne out by its service record too. Several L-1011's have survived incidents that might have brought down a DC-10 (such as one which lost the fan disk on its #2 engine- a similar failure to that which caused the Sioux City DC-10 crash). Unfortunately, the penalties paid for over-building (increased weight, decreased payload and range) are far more visible on the bottom line of an airline's accounting system than the statistical odds of better survivability. Also, the Rolls-Royce RB211 debacle hurt the L-1011 by delaying its launch, raising doubts about its viability, and giving the competing DC-10 a leg up on orders. Unfortunately for Lockheed, they were married to the RB.211 and there was no altertnative engine, so a delay in the engine meant bad news for the whole airframe (Hmmm! Good thing no one built an airplane around the GE-90 or history might have repeated!) -- Stephen G. Lacker (slacker at arlut dot utexas dot edu) <- convert to normal email format to mail to me.
