A few questions about Boeing's old rumor 757-Plus and 767X

Wed Apr 28, 2021 12:59 pm

I just realized it has been exactly a year since reuters informed of a possible 757-Plus and 767X coming from Boeing. The 767X would be a refresh to the old 767, be based off of the 767-400ER, and would be aimed for the cargo market. The 757-Plus would have be a 757-like plane to directly combat the 321XLR from Airbus. ... SL5N2CF5PN

We even had a mega-thread about it on here

However, I have a few questions about it as a whole.

What exactly is the 757-Plus? In the article, it said a 757-like plane, which I also assume to be a clean sheet design, but then why would it have the name 757 in it? From the name, it seems to be a plane with new technologies "plussed" onto the 757.

The second question is, how would they build them? I'm not going to resurrect the Bring Back 757 discussion, so please don't turn it into that. If they don't have the tooling for the 757, then how would they build it? I'm still assuming it's clean sheet, but why would it have the name 757? For the 767-400ERX-F it might be easier, because 767 is still in production, but the -400 is the only one no longer being produced out of the 3 basic 767 variants (-200, -300, -400).

The last is, are they still considering it? I mean, on the whole, they look cheaper to produce than a clean sheet, have roots to existing designs, and would keep the Anetters happy, but then again, the tooling and all would be a big investment.

Thanks for answering (and once again, please don't turn this to a "Bring back the 757." thing.

Regarding the "757-Plus", best guess based on aerospace media reports is that Boeing has added a third member to the proposed NMA family - NMA-5 - which will seat around 225 in two classes and would be sized around the A321-200/757-200 with a maximum range of around 5000nm. We've been discussing it at length (along with the larger NMA-6 and NMA-7) at viewtopic.php?f=3&t=1457171.

As for the "767X", there has been nothing new on that part. It is possible Boeing has shelved it and instead will make a cargo version of NMA-7 available in concurrence with the passenger model (or perhaps even start with a cargo model for NMA-7) should those models launch depending on customer interest,

I think the 757plus debacle came about as a result of people seeing what they wanted to.

If you were told I was building an aircraft similar to the 707, would you assume I was just modifying an old 707? Or that I was building a plane of similar size, range and capabilities?

Same problem. From what I understand, it was never a 757 design or derivative. It was an aircraft that is yet to be designed or named, that would compete in roughly the same areas that the 757 previously had, that is currently occupied by the a321.

I remember one of the first proposals for the 757 incorporated a 2000USG stabilizer fuel tank, improved efficiency RR engines and the cockpit from the 767-400 (this was installed and tested in a 757) along with other aerodynamic tweaks and additional composites it projected a range of over 5000NM

Great shame it didn’t happen
