Five engine aircraft

Cockpit?  We don't needed no stinkin' cockpit! :)

The Zut Alors 945?

I have heard that Boeing flew the 367-80 ("Dash 80), prototype for the 707, with a 5th engine on the tail for systems testing in the 727 program.  I found a picture at the following URL.  Can't figure out how to insert picture into the post.

Why do I keep thinking of a 727/737 cross with a stretched fuselage and five engines?

Cuz it makes kitbashing sense.

How about SEVEN engines?

I can only think of two, the B-47 that Orenda used to flight test the Iroquois engine in Canada, and the B-52 that was used to test the CF-6 engine under an inboard wing pylon.

Now someone will come up with a NINE engine aircraft I bet!

Oh I like that!  DO tell us more please!  :)

Yes, indeed - I'd love to see a few more views of this monster!

 The Kalinin K-7 was mentioned above -what about a five-engined version with bigger engines?

Why does this look like it belongs in the Luftwaffe at first glance?  I think its the sharp paint demarcation lines and the prop spinners.  Gives it a bit of a Dornier flavor until you realize its a Lanc

Yeah, quoting yourself's not a good sign, but, since Boeing used a common fuselage cross-section, how about splicing a 727 back end on a stretched 707, perhaps with winglets?  Or take it one step farther and replace the under-wing and outside-tail engines with JT8D-200's or CFM56's?

While Boeing knew they all had similar fuselage sections the model manufacturers never seemed to grasp that fact. You'd be amazed at the number of different sections they've managed to produce. I tried to do something like that years ago using a couple of Frog 707s and an Airfix 727-100 but would they fit? NO way! I still have the wreckage somewhere, maybe I should dig it out and try again.

Actually now I think about it, they may have been two Airfix 727s and a singular Frog 707 but you get the idea.

While the upper lobes are all basically the same, the lower lobes can differ by a great deal, and the 727 fuselage depth
is different fore and aft of the wing.

That's interesting Jon, there's 12" difference between the front and rear outside top to bottom on the 727, but only 10" height difference inside the cargo holds --
