Boeing Considers Developing a 757-PLUS Instead of New Mid-Market-Airplane Dubbed 797
 
Another "Here we go again." By the time it happens, the certification basis will be 40 years old. Come own, FAA, amend
14 CFR 21.101 Changed Product Rule so this "new" airplane meets the current safety standards the 797 would have had to.

And while they are ait, amend the delegation processes, particularly with regard to ODA.

BTW, can someone provide a link to said article(s)? I personally find the idea of re-introducing the 757 to be silly - is this really something coming out of Boeing, or is it fanciful speculation by an ignorant media?

That headline could have been written (and has been) at any time in the last 10 years, with as much likelihood of it happening.

Tango and Cash 8th May 2020 20:46

Persistent fanboy rumor on another aviation forum. The 757 production line is dead, the tooling has been scrapped, and it's going to stay that way. Amazing airplane for its day, but that day is passing.

That's actually decently insightful article. Funny how some people read:

Since then, Boeing has been looking at distilling the two-aircraft NMA programme into one new 757-style plane, while studying a more modest 767 upgrade, sources said.
and

A 757 replacement would counter strong sales of the Airbus A321 and allow Boeing to pioneer systems needed in future replacements of all small and medium jets - notably cockpits.
somehow think that means Boeing is going to reintroduce the 757...
Interesting to see that (at least per the linked article) Boeing is again looking at my preferred option for the mid-market - a '767X' with a new wing, engine, and avionics...

I said the same thing so ago now. That Boeing needs to bring back the 757 instead of trying to force a Boeing 737 to be a 757... cancelling the 757 was a very bad decision...just upgrade avionics, engines and wings.

The problem with simply replacing the 737 with the 757 was that the 757 cost much more to build. During the 757 development, it was assumed that jet fuel would be well over $5/gallon by the year 2000, so nearly every trade of cost vs. weight (or fuel burn) fell on the side of less weight/higher cost. For much of the next 20 years the focus went the other way - making the aircraft heavier but less expensive to build - but it still cost far more to build relative to the 737NG. Which is why the 757 eventually died - it's better capabilities relative to the 737NG didn't justify it's higher cost.
I really hope that whatever Boeing eventually replaces the 737 with has a new, wider fuselage. The 707/727/737/757 cross section is simply obsolete for the current generation of larger, wider passengers.

757 line was stopped more than 15 years ago purely due to a lack of demand. How people can keep kicking the dead horse...

Momoe 8th May 2020 21:57

757 was and is still a good aircraft, however 737 Max was (hopefully) the ultimate upgrade to an aircraft in continuous production since the 60's. Resurrecting an aircraft that first flew only 15 years later than the first 737 isn't going to happen.
Boeing have to develop world class solutions to make the 737 Max work and restore confidence in the brand.

It's all about the widebodies!

vikingivesterled 8th May 2020 23:00

That is the Reuters article, and another websites referal to it, I looked at wen when this was discussed on the "Boeing to cut 10%" thread.
"Any replacement would have slightly more range and seats, with one source nicknaming it “757-Plus” " was seen to be a reference to that 757-Plus was an internal workname used in Boeing.
There is more to this than can just be brushed off due to missing tooling. It can't all have been lost. The plane is still flying and one can still get spares. You can be sure the plans haven't gone missing.
The 767 is a widebody and can never be a quick and oversized fit straight into the airport parking spaces own stairs no belly containers 737 ExMax replacement. The 757 with a bit of more modern, economically optimized manufacturing, lighter composits and modern methoods of glueing and the latest most fuel efficient engines can. And the engines will fit actually under the wings. Also rumoured it can take off sanz tail scraping even without landing gear trickery.
Boeing don't need a mid market replacement. It has the 787. What it needs is a bread and butter plane it can sell and make in big volumes, within 3 to 4 years. Hopefully start preselling in 2 when the market comes back. Then having a tried and tested starter to modify speeds up the process.

PAXboy 8th May 2020 23:07

They can develop a brand new mid-size machine and CALL it the 757. It does not have to be BASED on the 75 other than approximate size and range. The 757+ could be a clean sheet design. They might just want to reuse the number to keep '9' for the future.

Una Due Tfc 8th May 2020 23:50

This is all based on the success of the evolutions of the A321. As TDRacer says, can Boeing really compete by evolving a very old design (757) ? There is generally a huge love of the 757 because it is an aesthetically pleasing design (especially with winglets), the love pilots have for it due performance, and the unintended niche in TATL flying it found in later life. How big is this market? Can it sustain 2 competing airframes when we consider crew currency? IE the crew can fly a Boeing equivalent of the A320 on a 2 hour sector today, then an 8 hour sector with an A321XLR equivalent overnight tomorrow on the same rating? Is it actually worth Boeing's expense to divide this market with Airbus? In a similar fashion to the B748 vs A388 argument....have both manufacturers lost...or have Boeing lost "less" because the B748 has the freighter variant.

I think we're mixing possibilities here. The 757 achieved what it did because of powerful engines, big wings and double bogey gear to get good runway performance and range at the expense of fuel burn due those thrusty engines at the expense of weight. In the modern world, are you better with two different types to achieve same mission or one type compromised in one to accommodate the other? No doubt a new bespoke design in the niche would knock Airbus' socks off, is the market in that niche big enough to justify the expense?.....

No where does it say the anonymous source was Boeing, or someone inside Boeing. And even if it was, any internal designations at this point are pretty much meaningless - the aircraft that became the 777 was initially called the the "767-X".

No, the tooling is long gone (except for some of the fuselage stuff common to the 737). The really expensive stuff is for the wing and that was the first to go to make space for expanded 737 production. Heck, most of the tooling for the C-17 is gone, and it's only been out of production for a few years. If you need primary structure for an existing 757, you'll probably have to go to the boneyard, or find someone that has the expertise to make one-off stuff. Yes, the drawings still exist, but not in the form necessary for 21st Century production methods. Developing and producing the tooling and manufacturing for a new aircraft costs a fortune - often more than the total engineering and development costs. Besides, you're still going to need a new wing and engines or you're going to end up with the same operating economics of a 737NG but with a bit more range... Avionics will nearly all need to be replaces simply because you simply can't buy avionics that were designed 40 years ago - keeping the avionics in the existing 757/767 fleet going is a never ending battle because nobody makes the components that were used 40 years ago.

Problem is McDonald Douglas execs shmoozed their way into the top jobs at Boeing..displacing all the engineer types that previously ran Boeing..set fire to the culture of the company and pushed all Boeing’s culture out the door. Now there’s not enough people in Boeing willing to call a spade a spade..and point out obvious flaws in designs..and the culture now punishes people for doing that anyway..so the question is; can Boeing even design a successful clean sheet passenger aircraft anymore..the answer I suspect is no..so that might lead credence to resurrection of old types rumors

Recent history would suggest that even is doubtful of current capabilities.

vikingivesterled 9th May 2020 10:54

tdracer - I fully agree that it would need a brand new multimodel cocpit updated to modern standards and prepared for the future of more automation. The body sould also be a composite play like the 787.
However, using the 757 as a template would not only create a good looking plane, as some comments have agreed with, but probably shave a couple of years, and associated costs, of the development cycle by reusing some of the principals like aerodynamic shape and and landing gear. Something Boeing desperately needs at the moment.
Personally I don't agree with this trend for ever larger 737's for the bread and butter jobs of short haul flying. The 150 seat aircraft was a more versatile one that encouragede more direct routes and higher frequencies. However the larger planes have been encouraged by slot restrictions, airport fees and increasing pilot costs.

All true, but who really cares? (tongue in cheek)

What do the airlines want?
When will they be interested in buying new planes again and at what price to get 20 years out of them?

There will be airlines looking to renew their fleets. Most customer don't care about cycles and flying hours. Arguments like technically it is 10 years old but this is really an 8 year old plane since it was parked up for 2 years, will not wash in marketing your newish fleet. It is not even an engineering truth since planes need to fly to be kept in top condition.
If you will get 20 years out of them in the northern hemisphere is a different question. It will depend on how persistent the envirnmental question will be after CoVid19. What I see is they have got a taste for the clean air demonstrated with the considerable, albeit temporary, downshift in pollution lately. And the governments in some countries have had to compromise with the environmental parties to get agreement on economical covid measures. These future promises will come back and bite us.
Price level on delivery in 3-4 years: Lightly discounted (nobody think they got a good deal without some discount) ExMax-10 for same amount of seats. A bit more with more seats. Relatively less with less seats. Since brand new cockpit 1 simulator thrown in with every 30 planes.

Pugilistic Animus 9th May 2020 16:52

I agree that the 757 can use a few inches more of cabin width. Just enough to beat Airbus by like an inch. I should be in charge of Boeing because I will try to resurect the 707 and 727 too :}

Not sure about it being bollocks - particularly this bit:

Additionally, it was disliked by passengers. Records show that it took up to eight minutes longer to board the Boeing 757-300 compared to the -200 series, thanks to the very long aisle. This same aisle meant that onboard service was incredibly slow, and passengers were waiting forever to be served.
I think this is what really hurt the 757-300 - it was simply too long for a single aisle. This made turn times horrible, and on-board service a nightmare - I sat near the back of a 757-300 one time, after we landed I timed it - it took 10 minutes after the door opened before there was even movement where I was sitting (I flew trans-Atlantic on a DC8-60 way back when - it had the same problem).
Direct operating costs per seat mile for the -300 were good, but it took so long to turn that it took a serious hit for productivity. Single aisle becomes problematic when you get much over 200 seats - twin aisle simply works better when you get much above 200 seats.

But not serious enough to prompt airlines to retire a single one of the 55 delivered.

Not an issue if you are primary a non-airbridge airline that use both doors and serve from both ends using 2 trolleys and 4 crew, plus a microwaveing runner when more than 200 seats.
Even if you use airbridges occasionally you can still use the back door for unloading with stairs and back up again onto the airbridge.

Wickerbill 10th May 2020 08:26

Tdracer makes a good point regarding turn times, but in almost every other respect the aircraft performance and economics are great. The 300 died with the entire 757 line in the depressed airline economics following 9/11. Not because companies, hated it; they weren't buying anything at the time. A bit like the next few years...

esscee 10th May 2020 09:03

Whatever they come up with, it will have to be a wider cabin with 2 aisles, single aisle is not going to be the way forward. Maybe offset seat row positioning so it is easier to get in/out of seats. Plus we may see some more radical or spectacular designs.

Hey, why stop there. I can see a market for the return of the 307 Stratoliner.:E

Turbine D 10th May 2020 21:51

Should Boeing decide to lengthen the current 757, I hope they do a better structural design than Douglas did in lengthening the DC-8 to the DC-8-61. If you sat in one of the rearmost row of seats and the aircraft was experiencing moderate turbulence, it gave one the feeling the rear section was going to torque off from the sections more forward, it was so visibly noticeable. It scared the heck out of unknowing passengers...

The 757-300 was much the same.

While it's true that 9/11 killed the market for just about everything, Boeing didn't pull the plug on the 757 until 2004, at which time the market in general was rebounding. Even with a rebounding market, they couldn't sell 757s because nearly everyone was picking the far less expensive 737NG instead - in fact the NG was selling like the proverbial hot cakes. A big part of the decision to kill the 757 was because all that factory space that was devoted to building one or two 757s per month could instead be used to build another 10 or 20 more profitable 737s per month.

On the contrary, that built in flexibility was key to the strength of the airframe, better to bend than break


Look at the incredible longevity of the DC8 and you’ll realize Douglas got it right

Pugilistic Animus 11th May 2020 00:45

I think that NASA owned/owns a DC8 as a general flying testbed for various things

Momoe 11th May 2020 08:26

It's going to very difficult to predict what is going to happen on the passenger side of aviation, it is fairly safe to say that passenger volume will be down in the short-medium term; Other drivers are home working/massive take up of video-conferencing as an alternative to face-to-face meetings and concerns about travel on any form of public transport.

Efficient single aisle will be preferred to keep costs down as volume won't be there. 777 with 300/350 seats, it's efficient but how many seats need to be filled to break even? And that's assuming that social distancing won't apply to airlines.
UK is introducing a 14 day quarantine for international flights which is going to have a massive impact.

The aviation industry is going to contract and Boeing/Airbus will not have the cash flow to launch any new aircraft for a while. Doesn't look good for the Max, even if you were in the market for a new plane, would you buy?
