Via the Drudge Report:

The National Labor Relations Board has dropped its controversial case against airline manufacturer Boeing, which had become a lightning rod for conservatives.

The labor board argued for much of the past year that Boeing decided to locate a new plant to build its new 787 Dreamliner jets in South Carolina, a right-to-work state, in retaliation for strikes by unionized workers at its existing facilities in Washington state.

But the panel appeared to bow to political pressure Friday, saying that a deal the company reached this month with the International Association of Machinists to build a different type of airliner, the 737 Max, in Washington satisfied its concerns.

Get an insider's peek into Boeing's Transonic Wind Tunnel testing lab, where technicians hover around a small scale replica of the Boeing 737 MAX. They're conducting tests on the MAX's new Advanced Technology winglet. The results of these high-accuracy tests will tell if the new winglet measures up to its desired effect.

Boeing has unveiled the super-efficient winglet design which will be incorporated into the 737 MAX design and production system plans. Check it out in this new video with animation of the 737 MAX. Find out more at www.newairplane.com/737max

Boeing Launches Higher Capacity 737 MAX Variant
Jul 14, 2014 Guy Norris | ShowNews

Source:
http://aviationweek.com/farnborough-2014/boeing-launches-higher-capacity-737-max-variant

Farnborough -- Boeing is to offer a higher capacity variant of the 737-8, a member of the new MAX family, to further improve seat-mile operating economics and increase competitiveness against the Airbus A320neo.

The minor model derivative will incorporate the mid-fuselage extra passenger exit door of the higher capacity 215-seat 737-9 to satisfy regulatory safety emergency evacuation requirements. The modification will give the new sub-model seating for up to 200, or around 11 more than the standard configuration of the 737-8. “It will have 5% better operating costs for a little less than a 1% dip on trip costs,” says Boeing Commercial Airplanes Vice Chairman and CEO, Ray Conner.

The variant, which at least for the moment is dubbed the 737-8MAX (to differentiate it from the original 737-MAX8 designation) will “take advantage of the extra 88 inches of space in the cabin,” says Conner referring to the longer internal dimensions of the 737-800/MAX -8 cabin compared to the A320. The decision was taken to offer the derivative at this relatively late stage in the MAX program because “we got a lot more comfortable with where we are, and as performance has continued to improve over the course of year. It was a matter of comfort and whether the customer base showed interest,” Conner adds.

The variant will become available after the three main 737 MAX models, the –7, -8 and -9, are developed and certificated. The current schedule calls for the 737-8 to be certified first in 2017, the -9 in 2018 and the -7 in 2019. The A320neo currently has 2,843 firm orders versus the 2,099 for the MAX.

Great looking aircraft, unfortunate that the merely re-engined NEO is still well ahead on orders.

Interesting that the serrated nacelle is back. I would have thought that the solution adopted for the 777x could be applied on all follow-on aircraft. I remember reading the oversized windows on the 787 were made possible by the carbon fiber construction. I guess aluminum can work too.

Very satisfactory that NEO, a thorough update of an already much more advanced aircraft, has such a lead in orders.

First flight of the 737 MAX is now set for Friday, January 29, 2016. :)

How history might have been different had Boeing not been so resistant to redesigning the 737's wing for the -300. They increased the chord with a new slat, added a tip extension and called it a day. Was it just a case of saving time and money or were they really that confident in their product?

Edit: I found this in Flight's archive, regarding the -300 wing 4.4% chord extension:

The modification is a clever way of altering airflow over the wing, particularly the
top surface, so that it approaches that an aft-loaded or supercritical section. The
result is a 4 per cent improvement in aerodynamic efficiency, equivalent to an
increase in cruise Mach number of 0-02 and a fuel saving of 1.5 - 3 per cent ranges
of 200-1,500 n.m.
15 years later they had to bite the bullet and created the wonderful 737NG wing, which finally matched or exceeded the A320's wing. Had they done that back in the early 1980s the A320 would have had a much tougher fight against the -400 as a 727-replacement, and perhaps we would have more innovative successors than midlly warmed-over re-engining projects.

Don't know if they are changing the routine from Farnborough.

There seems to be something wrong with their '*&oody airplanes'. Doing nothing will hardly improve trust levels.

It seems that they are grounded in the U.S. now

I don't understand why they gave the high authority autopilot an algorithm to push the nose down at all.
Every pilot knows that you either need to increase thrust A LOT or pitch the nose down when there's an acoustic stall warning.
Thrust isn't much of an option in airliners because of poor thrust:weight ratio, so pilots would pitch down unless they totally lost orientation and violate basic rules of flying.

Stick pusher have been around for 70 years...

Airbus don't require a stick pusher; the ctr law are simply impaired, what means that whatever you ask it won't allow.

Boeing are direct ctrl plane: hands on stick and not a push buttons (think Thrustmaster and Playstation).
Today with the massification of flights (and flight hours obviously) we face a lot of various surfacing problems that seems to tackle the sane logic of 100th old Boeing: long hours pilots deemed senior flyer that have been conditioned by aitbus "relaxed" authority (you delegate your inputs to the ctrl software) and young pilot with hours on console that start any critical reflexion only after having pressed 100 time repeatedly on a push button. Those are conflicting worlds and I fear that mixing both would lead us only to disaster like that.

Boeing should assume their philosophy of flight (the sane one IMOHO - especially with all the unforeseen problems with global warming - think flows mechanics for example) and sponsor their own accredited flight syllabus.

yes, you get it, you'll be a Boeing/Embraer/[today] Bombardier qualified pilot or a... button pusher.

On a thread on Keypub, I even put frwd that flight interfaces (ctrl law, avionic, cockpit disposition) would have to be commune cross platform and across airframer. It obviously lead us to delegating a lot of flight responsibility to the ground team via datalink.
