I like it as well and I am excited to see another version of the good old 737, the aircraft on which I had most flights so far...

Just one comment, if you allow me. I might be wrong but I think I would have preferred the dreamliner-colours instead of this dark-blue-green colour at the front section:

I think the dreamliner's blue at the front section Looks kind of friendlier.

Once again congratulations to Boeing.

Would love to see a pic of the Jurassic, Classic with and without winglets, New Gen with and without winglets and the Max sorta like they did the Boeing family pic that they did from the 707 to 777 at Boeing field once.

Great idea

The heck you lecture us on "scientific fact." Truth is, the 737 is a beautiful looking plane! Who cares if it's 50 years old! No one looks at a P-51 or DC-3 and says they're ugly!

Pot, kettle much? You just chastised another person for trying to present his opinion on the MAX's looks as facts, then tried to present a "fact" yourself. There is no "truth" on the 737's looks. It is ugly to some people and good looking to others

So what rolls out next, the Max -7 or the Max -9 test frame?

Next two roll outs will be MAX-8 aircraft.

MAX-9 comes after MAX-8, followed by MAX-7.

Apparently Boeing let go of the B-17 landing gear lever for the MAX, and installed two position landing gear lever. This is cutting edge stuff...

i can't wait to fly on one of those!

but in general a very sad day for us. this 737 has lost all the grace and style of the classic 100/200 series. it has no soul any more and is not a max, but a compromise in every way. it's a sad reaction to a warmed up A320(NEO), that with the GTF will offer superior performance. the MAX feels as if boeing did some more surgery on david hasselhoff and now rolls him out as MAX.

as much as i feel that the 787/350 are ugly planes, they are at least something new... and with it's slight nose up tendency this 737 is even more disturbing to my taste.

congrats to boeing and airbus as well in this case for coming up with exactly zero. at least the NEO will have a different engine impression to it during flight, i have a feeling that the MAX will sound and feel the same as a NG, except for the airbus winglets on steroids.

thank you bombardier for the c-series, at least something new. but please sell it and don't go belly up, or we will have even more MAX/NEO disgrace....

Quoting Ruscoe (Reply 119):
I thought you guys would be happy, because it means the 320 LEAP will be performing also.

I try not to be a fan boy of either. I am not a fan of the 737 but I do recognise it as an awesome peice of engineering that has survived extremely (more than that really) in a world of great technological change. Remember it's designs were probably laid down fewer years after the birth of flight than it has endured itself - amazing.

What we have competeing on the engine front - where really most of the action is these days are two competeing philosophies. The CFM56 has really up to now made the SA market place it's own. The reliability when the engines are cycled so often is truely remarkable. But to meet the performance required to challenge the GTF they have had to push the boundaries of material technology in order to get the thermal efficiencies. They have also had to increase the number of stages - although there is some doubt from Lightsaber, who knows far more than I do, whether they have sufficient stages for the work they need to do.

I worry that the LEAP will struggle initially with performance and long term with reliability and maintenance costs. Those high temperature exotic materials and mulitple stages need to work well. I do however expect CFM to make it work in the longer term.

Just another 737. I suspect by the time it has been in service for 20 years, it will look very dated.

Still I don't suppose most of the customers who travel on them will even notice or care one way or another as long as they get where they are going on time.

Congrats to Boeing.

Boeing will just replace any interior items that have suffered wear and tear. The customer taking this frame (WN) is already getting a discount and knows that the plane is going to be used as a test bed (if WN did not agree Boeing would find someone else to take the plane). It is not like Boeing is going "surprise you thought you were getting a brand new plane off the assembly line but we are going to give you a slightly used test aircraft instead!"

The 737 MAX will likely be the last development of the 737 design itself. What will replace it probably 10-15 years from now is something that will look radically different, a design that will have even lower fuel burn and much lower noise levels.

Lots of predictable sour grapes and "oh, just another 737" comments. IT must really stick in some folks craw that Boeing can still compete with the 737.

Though I am certain this will be the last 737 revamp. But that's not a bad thing though, when the last 737 Max rolls off the line, it will be anywhere up to 70 years from the first 737-100 rolling out. I don't care what anyone says... that's impressive.

This new 737 looks the part. I'm digging those winglets and the new tail cone!
I also like the jacked up gear. I wasn't sure I would but it make it look a little less squat.

It looks a little awkward to me, the mix of new and old doesn't quite fit and I expect it will take some getting used to. This is probably the ugliest 737 variant for me, the 737 always had the upper hand against the A320 in terms of looks but this time I think the A320neo actually looks better.

Still, congratulations to Boeing on the achievement!

That's even better than the DC-3. I think the Twotter still beats it, though. But still, very impressive.

For those of you calling this aircraft ugly:

The nose is the same nose found on the 707 and 727. You aren't going to call those ugly, are you? Better not. The 731 and 732 were ugly because they were short and stubby, but the 738 and 739 have a length/width ratio comparable to the 727 and 707. Visually, this is basically a twin-engined 707 with a different tail and shorter gear.

What a bunch of drivel. Both the NEO and MAX are derivatives of existing airliners. The MAX had to have more changes to accommodate the larger engine. Both airplanes are different from when they were first introduced. Both will probably continue to change over their remaining service life.

The NEO will have two engine options much like the CEO. The MAX will have one family of engines like the NG. The MAX is improving in sales, so we don't know what the final split will be. Most of the comments, strongly pro or con for either model, with the possible exception of comparisons between the A321 and the 9max reflect biases and preconceived notions. Both planes are selling well and both manufacturers are gearing up for unprecedented production volumes.

Why don't we just sit back and enjoy the show?

The MAX outsold the NEO in only one year - 2012 - and seems to have slid quite a bit since then. This may not be the most up to date info but is essentially current. I simply don't see where the MAX is improving? If anything, they seem to have lost some steam, but that's just my take on it.

Quoting StTim (Reply 31):
The MAX has different engines with different weight, centre of gravity etc. This will cause a change to the flight dynamics. So this must be fully tested. This will include the test where they effectively drag the tail on the ground to find the lowest velocity at which the plane will fly. There will also be flutter tests.

Yep. The crosswind performance is much different as well as what your good summary noted.

Quoting Ruscoe (Reply 95):
The new single-aisle airplane will deliver 20 percent lower fuel use than the first Next-Generation 737s and the lowest operating costs in its class – 8 percent per seat less than the A320neo.

Ummm... That is quoting the brochure. They need at least 400 hours of flight test information to say. GE/CFM does a better job of writing specs and component testing than Pratt. I give them that.

But the LEAP was a reaction. That has risk. I won't claim to be unbiased. I think everyone knows how much I'm rooting for the GTF. But I'm hearing issues with the LEAP. Half the issue will be fixed by May. The other issue wasn't found until NEO flight test. I do not know the root cause, so I cannot speculate on the time to a fix.

To be fair, the NEO did have a year and a half start.

Why is the MAX engine having chevrons? I know they reduce noise, but I thought they add a little bit of fuelburn, too? AFAIK Boeing removed the Chevrons from the 77X for this reason. So why keep them on the MAX when the LEAP might not meet fuelburn targets?

Classic FUD manoeuvre to try and put customers off buying the competitor's product.

If Boeing had launched NSA instead of MAX it would not have been available for many years and Boeing's customers wanted a more efficient plane sooner. Eventually, Boeing had no choice but to launch MAX.

They had the noise margin on the 777x, so they were able to remove the chevrons and capture a small fuel savings.

Apparently they couldn't achieve desired noise levels without the chevrons on 737MAX, so they stay despite their small fuel penalty.

The falsehood is that people put way too much emphasis on 'Launch.' Sure it'll get you an initial burst of orders, but that's about it. When you can get your product into customers hands (EIS and ramp-up) is what matters. And there the NEO does have an 18 month head start.

They had the noise margin on the 777x, so they were able to remove the chevrons and capture a small fuel savings.

Apparently they couldn't achieve desired noise levels without the chevrons on 737MAX, so they stay despite their small fuel penalty.

And the 737 is far more likely to be flying into noise-restricted airports (SNA for example) than the 777.

I also read an article from April of this year stating that Boeing's LEAP may be missing SFC by 5%. Is that an issue for Boeing? Here's the article link:

In a word... no.  

WTI has traded today at $36 (down 11% in just the past month) and the IEA now is saying that oil will remain low for all of 2016. What is 5% when oil has dropped close to 70% since June a year ago.

5% when oil was $114 compared to 5% with oil below $40 is obviously very different.

Lots of predictable sour grapes and "oh, just another 737" comments. IT must really stick in some folks craw that Boeing can still compete with the 737.

It's not sour grapes, it's just dull. Same thing with the A320 neo, except at least that one looks slightly different.

I'd argue the visual differences between the 737NG and 737MAX are greater than the A320ceo and A320neo. The Neo looks exactly like a sharklet A320 except with larger engines (because that is basically what it is!). The MAX, while not having as dramatic of a difference in engine size, has completely new wingtips, tail cone/shape, and a different stance (level versus nose down).

The A320 NEO looks even less radical than the 737 MAX. I do like the honkin' engines on the A320 NEO though.

I'm not a fan of the 737 MAX but it looks far more appealing the "exciting" to the eye. The split winglets, the tail cone, the engines, the sleek classic Boeing nose. The A320 series is the dullest commercial aircraft ever created. There is nothing really aesthetically unique about it. At least the winglets and bigger engines made it slightly less boring. I still think it's clear which aircraft will stand out more to the average spotter.

Good luck to Boeing on this newest 737. I'm mostly looking forward to the NSA though.

The CEO was not initially to receive the sharklets. It was was a NEO only change. If you don't count that towards a change for The NEO, then you should not count the new wing tips for the max as they are not that different than the split scimitar being modified to the current blended winglet other than it is built as one piece and made by two different companies. It's just Boeing stuck to their word unlike Airbus when they said they would not be retrofittable.

It was always the plan for the CEO to get sharklets- in fact they were launched a year before the A320neo even was (Nov 2009 vs Dec 2010). Airbus had been studying various winglets designs since the mid 2000s, especially at the behest of B6 who was always looking at options to increase the A320's transcon performance in the winter months, until eventually settling on the sharklets:

Note how every winglet I posted is different. I believe most of the older designs' fuel burn benefits were canceled out by the increase weight to add the winglet.

The NEO's sharklets are identical to the CEO's sharklets. As you acknowledge the MAX's split scimitars are not identical to the NG's.

Boeing claim the Chevrons also reduce cabin noise in the rear of the aircraft. In the case of the 787 they were able to remove some planned insulation, and apart from airport noise, same may be true for MAX.

Boeing's come a long way for the 737 program since its inception in the 1960's. I'm very impressed and happy for them, nice sexy looking airplane with state of the art flight deck, fuel efficient engines with chevrons for environmental noise reduction, and the final MAX series for the 737 program. Very beautiful, next time I fly with Southwest Airlines, I'll make sure its the new 737 MAX God willing.
