What passenger jets thru the years have never been more than concepts or vapor trails ?
Ive heard about the Avro Jetliner, The Lockheed Bi-jet and more recently the Sonic Cruiser. The Boeing 2707 is well known.
Didnt Japan make a jet that never went beyond prototype ?
Ive also read about the double deck (or double bodied) VC10 and a Hawker Siddeley "757" look a like.
Any others that never made it beyond the drawing board or got further than test flights ?
So far in 2008 45 flights and Gold already. JFK, IAD, LGA, SIN, HKG, NRT, AKL, PPT, LAX still to book ! Home Airport LCY

Embraer has made huge strides in this area, introducing the likes of the EMB-190, making competition difficult. The Russians have the Tu-334, Antonov An-74, and Ilyushin Il-114, which have been produced only in small numbers.
The Shanghai Aircraft Manufacture Factory created the Y-10 (Yunshunji, air transport), the first passenger jet airliner designed and built in China. She was a four-engined medium- to long-range airliner similar in size and layout to Boeing's 720 and poweres by four P&W JT-3Ds, spares from CAAC's fleet of Boeing 707-3J6s. Only one plane was built (first flown in 1980), with another airframe retained for static tests. http://en.wikipedia.org/wiki/Shanghai_Y-10 http://www.samf.cn/fjzzEN.htm http://community.webshots.com/album/194607929qiSdUz (my collection)
There is also the Antonov An-70, an impressive Ukranian turboprop cargo plane, of which only one or two protoypes have been built:
Another passenger jet that never made it was a turbojet version of the Saunders-Roe Princess, a huge double-deck flying boat. And for civil versions of military aircraft that never made it beyond the drawing board, see my collection here: http://community.webshots.com/album/362079242OabZwt

A few more recent examples:
717-100 & 717-300. The 717-100 would have been a shrink of the 717-200, and would have been around the size of the DC-9-10/20. Would have been powered by either a derated version of the BR-715 or by the BR-710. What killed it was the CRJ-700 and CRJ-900 and the Embraer E-Jets family. The 717-300 would have been a stretch of the 717-200 that would have used the same engines as the 712, but would have been around the size of the MD-87 with a similar capacity.
727-300. Was to have been a stretched version of the 727-200, with an improved wings, improved engines, and new landing gear. United and Braniff had expressed interest in the a/c, and the project was publicy announced only to collapse when United decided not to order it.

Wasn't there a concept for a three-engined 747 kicking around in the 70's? I'm sure I saw an impression/drawing of one a few years ago. I think it was called the 747SP with a tailmounted #2 engine. From what I understand, the concept was nixed because the airflow over the 'hump' severely decreased the efficiency of #2.

I know that Bristol did some experimenting with a jet aircraft right after they launched the Bristol Britannia. It had a look resempling that of an enlarged fighter jet, and it did see progression beyond the drawing bord. A prototype was actually built and it was successfully flown too to my knowledge.
I am not sure what prevented the launch. The lack of orders or interest are the likely culprits. Unreliable or lack of available engines could have caused that too.

My favorite is MD-12, Douglas makes essentially something identical to A380 a decade sooner, only to capitulate and have the french run with the idea.

Quoting IFEMaster (Reply 14): There's a thought...maybe a 5-engine jet would be good. A Quinjet. Two on each wing and one at the tail.
Lol, the 5th engine is there to propel and carry its own weight.. and I have to agree with IFEMaster, it would definitely suck its max range capability..

What about the 747-500X and the 747-600X? Also, the Boeing SSC? Embraer recently shelved one of its RJ project didn't they? And I'd say, looking at current trends, the 737-900ER and the 747-8I would never make it either (though it is being built at the moment..)
