What Cockpit? MK VI
I must have forgotten the number of wing struts: your photo clearly shows one massive lift strut, two bracing struts outboard, one bracing strut inboard as well the wide chord landing gear strut fairing. All the drag created by those struts probably exceeded whatever efficiencies were gained by the very high aspect ratio wing.
Twochai, back during the construction days of the QNS&L-RR, Hollinger Ungava operated a PB, CF-DIK, along with the DC-3's. One day both the Canso and one of the DC-3's were going into Knob Lake around the same time. The -3 was below the Canso and was overtaking them, when the Captain - can't remember who it was, probably George Humphries - looked down and saw the DC-3. He firewalled the throttles, dove the Canso and overtook them, and as he went by he feathered the left engine. Somebody on the DC-3 snapped a picture of the Canso going by the DC-3 with a prop feathered. I'd love to get my hands on a copy of that pic. 
Altitude wins, every time, particularly in a pigboat!
OK, let's get back on topic, here's my challenge once again. Clue: it does not have a high aspect ratio!

The cockpit glazing and overhead throttles looked vaguely flying boat like, but who would fit EFIS and a HUD to a flying boat? It is also clearly a flight test aircraft, with the extra instrumentation and the special right seat yoke.
The big side windows looked vaguely familiar and then I remembered. None of your Boeing and MD rubbish - it's de Havilland Canada
, although admittedly Americanized. 
Specifically it's the highly modified C-8A Buffalo NASA/AMES QSRA aircraft N715NA. Pictures here http://dhc4and5.org/Buffalo9.html

Well, the Buffalo, YC-14, YC-15 each have relevance, as does the C-17! However India Four Two is the only one to get it exactly right.
QSRA (Quiet STOL Research Aircraft) was one of the Buffalo prototypes modified by Boeing with a new wing, Lycoming LF502 turbofans (leftovers from the Canadair Challenger development program, in fact) and all new flight control system.
The QSRA proved the Upper Surface Blown (USB) aerodynamic concepts which enabled the Boeing YC-14, which lost out to McDD with the YC-15 in the competition for the C-17 airlifter. Of course, Boeing won out in the end when they later bought McDD for peanuts - the C-17 contract was the best asset on the books!
The QSRA was a contemporary of the deHavilland designed, RR Pegasus engined augmentor wing research aircraft which, while arguably more efficient from an aero perspective, was anything but quiet as a prototype (think, two Harriers in formation)!!
Over to you India Four Two, you have the wheel.

Thanks, twochai.
To be fair, Boeing built a new wing for the QSRA, so it's an early example of NAFTA co-operation
Here's one that I am surprised we haven't seen before.

twochai,
I said I was surprised it hadn't been done before and we have to get all the easy ones off the table!
Show us what you've got!

OK, OK, OK, I can't stand it when people avoid responsibility!
Here's another easy one that I'm very surprised has not been covered. No comment on the wing's aspect ratio.

Thank you Twochai, I think this will be another of my "nano seconds" posts ?? but hey, lets see, I must be in bed very soon, so I may be gone for some time !! Keith.
