Remember The Double-Decker DC-10 Proposal?

I was recently looking through an aviation book on the McDonnell Douglas DC-10.......and something quite interesting caught my eye........

In 1966, an early proposal for the DC-10 aircraft included a huge, 4-engined FULL double-decker design, with potential seating for up to 550 pax!

The artist's rendering of the proposed plane looks very much like Airbus' upcoming A380 Jumbo.......even BETTER looking, I thought!

This two-story "DC-10 that never was" had a nicer tapered look to it (comparing it to the A380), esp. the nose.

This mega-DC10 was obviously abandoned by Douglas due to a lack of customers at that time for such an enormous transport.

Does anyone remember this unique DC-10 design?

Any other insights into it?

Would YOU have liked to see this Superjet fly?

I think that Douglas had plans for this a/c later then 1960, because I've seen drawings and then it was dubbed the MD-12. I don't think that MDC could develop this a/c without a huge risk of killing itself. I don't think they wanted to take that risk.

Just like birdwatching - without having to be so damned quiet!

Thanks GOT.........

I didn't say "1960" in my post.

It says 1966 for that double-decked idea. (That's the info I have....'66.)

I don't remember the DC-10 proposal....but I do remember when Pan American World Airways put in its order for a number of Convair C-99's...one of the earliest full twin deck aircraft ever built. However, the order was cancelled. If I am not mistaken, they cancelled because of jet transportation on the horizon.

Interesting that MD was already designing a DC-10 derivative years before the original DC-10 every flew. It is normally the other way around.

The MD-12 was an imaginary plane concocted in the early-90s and bore a striking resemblence to the A-380. The MD-12 however, should not be confused with the MD-12X which was a stretched version of the MD-11, that also never got off the ground (MD-12X). The MD-12X project was abandoned only months before the Boeing takeover. I think 'they' knew something.

Mac....Interesting.

Another rather unique design was with the B747.
One proposal for the four-seven was for the flight deck to be situated BELOW the main passenger cabin....rather than above it.

Any remember this one?

Hi IFLYADESK.................

No, no.

The double-deck design I speak of was NOT to be a derivative of the original DC-10........the double-decker WAS to be the original DC-10!

Imagine the derivatives IF this superjet design was actually built......."McDonnell Douglas today announced plans for a stretched version of its very successful DC-10 Double-Decker SuperJet. It will have a capacity of 685 seats and THREE decks!"

Love to see a triple-decker, huh?  Smile/happy/getting dizzy

Oh yeah, you are referring to the "double-bubble". I had completely forgot about that one, not exactly a wide-body. It was essentialy two DC-8 fuselages, one on top of the other. Wow, those were the days!

The below-floor seating was also considered as an option for the MD-12X replacing most of the forward cargo compartment, complete with down-angled windows. After considering problems with FAA certification, it was later tauted as an inflight lounge (not to be occupied during takeoff or landing).

Actually, the double bubble was an early 747 proposal. I do remember the "DC-380". It was in the back of an aviation magazine and the caption was, "what once was old is new again". I also now recall MD's crack at the double decker. ( MD-12 ) That was an attractive bird.

I've seen pics of both the mid 1960's double-deckers from Boeing and MDC, I think the double-deck 747 had a smaller width fuselage.
In the early/mid 1970's Boeing continued to look at a range of double-deck 747's and lengthened 747's, some of them double deckers too. These ultimate versions would have seated 1000 for domestic, and 732 for long range.
The recession at that time, plus engines not being developed as fast as anticipated killed the proposals, you can find out more in 'Boeing 747 Design and Development since 1969', by Guy Norris and Mark Wagner. (MBI Publishing), a highly recommended book.
To try and salvage the MD-12, MDC tried to subcontract most of the fuselage to Taiwan Aerospace in 1992, but the deal collasped at a very early stage of talks.
Also in 1966, BAC proposed a double-deck version of the narrow-body VC-10. BOAC were not interested and goverment aid was not forthcoming. It would have needed better engines than proposed for a decent range/payload, maybe the RB.178 then under development at Rolls-Royce. Seating would have been 286.
