And how exactly did Boeing expect North Korea to fund this? Or was this part of yet another harebrained scheme from Foggy Bottom, aka the US State Department?

Interesting, I have heard that there also exists a model (or models) of a Boeing 747 in the QANTAS 'V-Jet' (707) colour scheme that dates from around the time that QANTAS was looking into purchasing 747s.

From "Boeing 747" by Jens Flottau and Dietmar Plath, an early design for the B 747, already with the
characteristical hump, but with two full decks, besides the partial deck behind the cockpit.

The high wing and overall shape of the fuselage are identical to the Boeing Model 750 (C-5A), including the main gear fairings. Not much room left for passenger luggage in this design, however.

All carry-on luggage only? Sounds like Ryan Air would love that...

And what about this fighter model next to the 747-300, looks like a F-86 but is an F-86 or not?

The stand says "NAA - Transonic Interceptor" (can't read the smaller type) so it's most certainly a preview model of what became the F-86D.

Radar-equipped Sabre 45 variant?

Interesting find, hesham. Given the low resolution of the drawings themselves, it's hard to tell, but it looks like the one on the left is a stretched 747 with a full-length upper deck.

I'm not sure it's the same animal, but it reminds me of the reports of the four stretch designs from April 1973, one of which had a stretch of 160 inches forward and 140 inches aft, and a full-length upper deck. That could carry 624 passengers.

Hello Hesham,

The only interpretation I've ever seen was this sketch, which has been published in several books on the 747. It turns out I had the wrong numbers, though: the stretched double-decker carried 732 passengers on long-range service.

What I would dearly love to know about any of these four proposals is this: did Boeing intend to use the same wing on these stretches? The drawing seems to imply that the wingbox stayed the same, but I cannot imagine how, for example, the 50-foot stretch variant could possibly use the same wing and engines as the 747-200B, not if they wanted it to fly appreciable distances.

These drawing still boggle my mind. That first stretch proposal is even larger than the 1996 747-600X, nearly three feet longer! It's the largest 747 proposal I know of.
