Due to their excessive noise, I propose a P-8 Poseidon utilizing propfans. These aircraft would then be used to intercept and scare off Russian Tupolev Bears. Give them a taste of their own medicine!  >:D ;D

Greg, my sources worked for Boeing at the time--and it came up in context of reservations about the hasty farm-out of major subassemblies and the large amount of technology-transfer on 787.

Multiple observers have voiced strong opinions to me that the first five to ten aircraft should have been built completely in-house to validate and debug the engineering, THEN start farming smaller pieces out to the subcontractors and progressively let them do more as they demonstrate they can deliver... those first few took a LOT of rework to assemble because A LOT of the subassemblies weren't as "Plug and Play" as they were designed to be due to manufacturing issues...

Don't press a lot on naming sources, as I get a lot of things that aren't supposed to be heard outside the company.

*nods* I can well believe this.  I'm quite familiar with how well the first B-2, which was subassembly "plug and play" on a masive scale, went together.  Let's just say that, IMHO, it should have remained a R&D aircraft and a new one added to the production order rather than bringing it up to near-production status (there's some flight test items you'll never get out without complete disassembly of the aircraft in addition to various issues that arose during assembly).

The six-engine variant could have two engines located at the tail as seen on the Tupelov Blinder bomber and the other four engines under the wings :)

Five-engined with two under the wings in addition to the tail engines?  Hmm, could JT8D-200 series engines fit under the wing?  You could then do new naclles for the tail engines ("borrow" from DC-9-80), a "fitted" JT8D-200 variant for the center engine (you're airflow limited by the intake and re-designing that is a non-trivial taks), and JT8D-200 nacelles under the wings.

Just add a four pack to the tail like a VC.10 and you'd be up to 10 engines.  Hmm, four more in the wing roots and that gives you 14...  I think that's enough for an airliner.

What if insert in tail fin base of a Boeing 707 at 1/144 the fuselage of a Tamiya MiG-19 at 1/100? ::)


... or perhaps add a pair of turboprops made with two fuselages of MiG-21 at 1/144? ???


... well, why not both?!  ;) 8)

In this book there are several drawings of projects/studies around Boeing 707 design.
http://www.amazon.com/Boeing-707-Pioneer-Jetliner-History/dp/0760306753/ref=sr_1_1?ie=UTF8&qid=1385264660&sr=8-1&keywords=boeing+707

pg 20
- Similar to B-47: 2 jet double pods and shoulder mounted swept wings.

pg 22
- Boeing model 473. Idem first one in pg 20, but only  2 engines
- Boeing model 473-25. Idem  first one in pg 20, but 6 engines: 4 jet pods 2 single inboard and 2 double outboard

pg 23
- Boeing model 473-47. Idem first one in pg 20, but low wings and only  2 engines. Smilar to Boeing 737 but straight tail surfaces and moderately swept wings.

pg 25
- Boeing model 707-6. Low wings 2 jet double pods. Very close to 367-80 (dash 80)

pg 28
- Boeing 707-7-27 like dash 80 but with 4 turboprops and wing tip tanks
- Boeing 707-7-39 like dash 80 but with 6 engines: 4 jet pods 2 single outboard and 2 double inboard, and wing tip tanks

pg 58
- Boeing 707-020 Shortened version with only 2 engines

pg 75
- Boeing 707-320-101 Double deck large-capasity (up to 250 passengers) version

All the following drawings are from a 17-page document on the origins of the 707. A local club member has been clearing out his file
boxes. I snagged this one.

I saw that Minicraft does an E-3/E-8 kit in 1/144 and also does a KC-135R.  I know they aren't the best, but I keep seeing both radomes on a CFM56-powered airframe.  Either that or mount both radomes on a 1/144 767 or 777 and use the remaining bits for more "out-there" whiffery.

Actually doable, a history of the 737 design states that the necessary provisions are there.  Perhaps just three drogue spots (fuselage and under each wing) rather than with a boom.  I wonder how a 727 tanker would fare?

When I was a kid I was really into the history and aircraft of NAC, the domestic forerunner to Air New Zealand. I made a 737-200 out of Lego to play with which, with less than 2min of mods, became a Fokker Friendship. Perhaps there are some ideas to be explored here?

Without planning it.  I happened to be at right place at right time to see first flight of 727.

I recall there was some interest in the late 90s early 2000s in a small tactical tanker that would actually also serve as a C3I node and possibly as a stand off jammer as well as a tanker in support of strike packages.  Rumour had it that Lockheed was working on something stealthy/sneaky off the books to fill the role but if it had existed and the high end stealthy version had been cancelled there could be a whiffie justification for a non stealthy 737 doing the job.

Considering the build BdB did turning 1/144 DC-6 into 1/72 Mugger.
http://beyondthesprues.com/Forum/index.php?topic=6619.msg113328#msg113328

1/144 727 JT8D engines scale comfortably 1/72 J85 engines.  Using three J85-GE-21 series engines otta provide sufficient thrust for jetliner speeds.
Could be a 1/72 tactical air-to-ground missileer or whatever........
