KC-10 (DC-10) air tanker a couple hundred(?) in service and almost 400 KC-135 (707 ) tankers still flying.The L-1011 coulda been a contender, RR just about killed Lockheed when they went on strike and held up RB-211 delivery. One of my oldest friends father was VP commercial sales at Lockheed. Had the delivery schedule been on time it would have had a different outcome. IT was a good airframe and the RAF and others still use them as tankers.
The "other" wide bodies like the L-1011 and DC-10/MD-11 never had the success the 74 did. The range alone put it in a class by itself for many years. Like the DC-3 the 747 will be flying long after many of its successors are just memories.
A clean sheet design is one that isn't directly derived from a previous design. Starting with a blank piece of paper, as it were.What do you mean by "clean sheet"?
Thank you sirA clean sheet design is one that isn't directly derived from a previous design. Starting with a blank piece of paper, as it were.
For example, a 737 Max 10 is a new airplane, but it was more-or-less derived from the 737 lineage. An A-380 was a clean sheet design, as was the 777.
So someone might make a freighter version of the A380, or make a super guppy out of an old 747, or something like that. But nobody is going to start with basic design principles and end up with a four engined aircraft anymore.
I could be wrong, of course, but it won't be a tube-and-pods subsonic airliner.
As mentioned above, the L1011 and DC10 came out virtually the same time and all were 2 aisle widebody planes. So it was what people were doing at that time.
"you could be assured that as soon as lines were placed on paper, someone would be suggesting "move this there"....Yep - when I was in the DO for new instruments this was the phrase - "lets get a clean sheet of paper on the board".
What was amazing was no one would ever comment on concept though....no "helping out".
BUT, you could be assured that as soon as lines were placed on paper, someone would be suggesting "move this there"....
They may have been a response to the 747 but they were all designed before the first 747 ever flew. 747 first flight 2/69 L1011 11/70. DC10 8/70Incorrect. DC-10 and L 1011 came out several years later, *in response to* the 747. (They were also pretty much the same plane, altho Lockheed's was better built).
This is similar to pony cars. Mustang created the market, or at least discovered it, then camaro and barracuda and challenger followed behind. "Everyone" was *not* "making wide-body jets" at that time. There was, in fact, a great deal of resistance to the idea.

Yes 747 was first, but yes everyone was building wide bodies
I like pickled eggs yet they are definately not really on my diet. I do enjoy eggs though as a cheating venture rarely.Best job (as a contractor) I ever had was working at the McD Wind Tunnel group (Long Beach) on the MD-12 which was going to be a challenger to the 747. Was there maybe 9 months. Great place to work.
One highlight was watching the C-17's first flight from the 3rd floor library of building 36. The lowlight was when they cancelled the MD-12, and I had to go back to the company who had loaned me out on contract
Ended that day playing pool in Joe Jost's in Long Beach. Well known for their pickled Eggs.
Wait who started with the cute little slurs?
And who used the Mustang comparison?
Mustang released 1964
Vehicle design cycle circa 1964: 3 years
Camaro released 1967
Those jets were in final design before the first 747 ever flew.
Not after it was a success
747 , first, best, biggest, but not only
