ObamaCare,
Fast and Furious.
Solondra,
Gas prices have doubled
Food prices up around 30%
average 4k in lost incomes,
First President to preside over a cut to the credit rating of the United States,
First President to spend a trillion dollars on shovel-ready jobs and later admit there was no such thing as shovel-ready jobs.
First President to tell a major manufacturing company in which state they are allowed to locate a factory, (Boeing) ,
First President to coddle American enemies while alienating Americas allies.,

The Obama Presidency is a Failed Presidency.

First of all, it was the kids father, who is a Iraq war veteran, who approached Obama. Not the other way around you nincampoop.
2nd, name one failure that makes Obama's presidency a "failed presidency".

Using Children as a pawns for a cover of a failed presidency.

Apparently adding a 1-ton 400 Megawatt air conditioner to a rocket engine improves efficiency. Who knew?

But it's just under 60% as efficient as a Boeing 747-400, so I hope this never happens.

Wonder what that sounded like in row 23?
I'm guessing it sounded like a synchronized gasp.

A part of me thinks that this is a beautiful piece of engineering, but another part of me feels sad that it'll only be used to drop bombs on people.

It is actually a spy plane, even so, any R&D you can point towards developing a hydrogen economy (provided we find good ways to produce hydrogen), the better!


Spy planes are used to spot places to drop bombs on them as well, it's a first strike weapon, like a "Missile Defense Shield."

One of the killer apps of the particular flavor of nuclear I am interested in deals with high heat electrolysis which could help in the transition to a hydrogen economy. Technologies that aid in hydrogen production will also most likely be suited for desalinization of water, which could be of great need if warming of the earth changes regional rain patters.

We don't see the entire test flight; they could well have raised the gear later. If they didn't raise the gear even later, it's because Boeing might have been (quite reasonably) afraid that they might not be able to get them down again (new jet, test flight, novel electronics systems, huge commercial pressures, etc etc etc). Every test flight has a specific menu list of things that are supposed to get done and each of those things gets done in sequence. You'll also notice the two chase planes that followed it to the horizon, watching for leaks, loose panels, anything that could threaten the test flight and safe return of the aircraft. And after all, it's not like the 787 has ejector seats---and, every time Boeing develops a new jetliner, it's betting the entire company's net worth. Prototypes can trash (see: Boeing B-17) So, slow and steady, nice and easy, careful as you can be.

Lockheed is the main contractor. They sub out some of the wings and tail section to Boeing. Pratt & Whitney make the engines. While the original order for the planes was over 200, I believe that has been cut in half (or more) since that. They usually have 3 engines per plane to make it easier to keep the plane going if an engine needs repair (there's 2 engines in the F/A 22, ones similar to the 1 engine in the Joint Strike Fighter). The F/A 22 project was the project before the Joint Strike Fighter, so a lot of the technology was shared between the projects.

Ria Novosti had an article about it the other day. Didn't expect the US press to pick up up so soon, to be honest.

Well who makes the F-22 Raptor? It's Lockheed Martin right? Built in conjunction with Boeing too huh...hmmm I wonder if the two largest receivers of government military contracts will get a pass in the media.
That is until the horde because too loud to ignore.

I wonder what will happen to that Boeing plane that used to carry the space shuttles.

also check this out someone already did a flapping one man flier ..probably on sift
http://www.zdnet.com/blog/emergingtech/human-powered-flapping-wing-plane-first-ever-to-take-flight-video/2388

"Built from carbon fiber, foam, and balsa wood, the Snowbird weighs just 94 lbs. and has a wingspan of 105 feet, which is comparable to that of a Boeing 737–amazingly, the Snowbird weighs less than all of the pillows on board.

The wings’ thrust is due primarily to a low-pressure region around the leading edge, which integrates to provide a force known as “leading-edge suction”. The wings also passively twist in response to the flapping. This is due to a structure that is torsionally compliant in just the right amount to allow efficient thrusting (”aeroelastic tailoring”). It should be noted, though, that twisting is required only to prevent flow separation on sections along the wing. It does not produce thrust in the same way as required by sharp-edged wings with little leading-edge suction."

nice speech but Lockheed, Halliburton, Boeing, Merck, Pzier would never let their country invest in stupid shit like this


It is a great irony that many of those companies were born of the space race
