3D model of a building. and this is just the start of the project.

Not really related to your post, but only slightly.

What do you think 3-D printing means for the future of architecture and construction?

love it for design purposes, still a bit concerned as far as actual construction goes just from a longevity standpoint. will definitely not see it as a structural material use in my life time. (i think, with how fast technology changes who knows)

*great for repairs/replacement of certain materials. I think maintenance is an area of great promise for 3D printing.

What happened here?

It looks like the group of helicopters were deploying infrared flares for demonstration purposes when the tail-rotor of the middle helicopter failed. Due to the this failure, the helicopter lost direction control. I believe that the pilot may have attempted an autorotation landing (cutting power to the engines and allowing the rotor to spin freely). Unfortunately, the landing didn't appear to go too well.

Edit:
After watching the video again, I realized that the helicopters entered a steep climb. The one that crashed must have entered a stall and subsequent spin that it was unable to recover from. I think the tail-rotor stopped operating because the pilot cut power and attempted an autoration landing like I previously mentioned.

No.

Spain bows down to us, so there's no need for her. This is all, therefore, completely legit.

Everywhere outside this orb, however, is false and the mere product of US meddling. So-called desires for self-determination, democracy, freedom, and more open economic systems are made up by the US State Dept.

Marines change European mission amid Russian aggression

That renewed Cold War-style emphasis, and the Marines saw Black Sea Rotational Force pick up several training missions across Eastern Europe. Over the past six months, they completed nine major exercises and 46 military-to-military engagements. That is compared to just six exercises and 22 military-to-military engagements, during the previous rotation.

The next rotation of Marines will be even busier. They already have seven scheduled exercises, and 45 military-to-military engagements, with the possibility of more to come.

Just wondering if there are any circumstances in which a pilot could still land one? Or is it doomed?

the guy with the bug name explained it way better than I could, he probably actually knows what he is talking about. sounds like he was saying that the pilot might have been trying to land in a "controlled freefall" so to speak. doesn't sound like it has a high probability of survival.

I found another video of the crash on Fox News. The report said that the helicopter experienced a mechanical failure and 1 pilot died and the other survived. So, I guess it was definitely a tail-rotor failure that caused it. That explains the spinning, since the tail-rotor is responsible for counteracting the torque from the main rotor.

I'm not a pilot, but I do have an interest in aircraft and helicopters, so I know a little about them. Here is a better explanation of autoration: In the case of engine failure, the rotor can be disengaged from the engine and the blades will keep turning due to the air coming up from below. You can actually land safely like this, depending a number of factors (weight, airspeed, etc.). This procedure can also be used if the tail-rotor fails, since the free spinning rotor doesn't produce torque. Obviously, in this case something didn't go right.

Why are you a Plecoptera?

I about jumped out of my couch, reading this one.

haha!

I've asked Plecoptera before about his name and his avatar.

Sadly, I cannot remember his response.

Plecoptera, help us out.

All I can remember is that he was researching something or another, and that that pic (the avatar) was from a close-up related to his research.

I'm an aquatic biologist. My avatar is a photo of a stonefly that I took through a microscope when I was in grad school several years ago. Stoneflies belong to the order Plecoptera, hence my name here on VN.

One of many here. Ha ha.

Analysis of Obama's foreign policy. Not the most favorable review.

How the Obama White House runs foreign policy

But on a host of other important issues, the NSC, designed in Harry Truman’s time to coordinate sometimes-conflicting diplomatic and defense views, is still widely seen as the place where policy becomes immobilized by indecision, plodding through months and sometimes years of repetitive White House meetings.

In addressing challenges where there is internal disagreement or there are no good options — civil war in Syria, Russians in Ukraine and military dictatorship in Egypt, for example — policymaking has been “sclerotic at best, constipated at worse,” a senior Defense Department official said.

“Time seems to be all this process produces. More time, more meetings, more discussions,” the official said.
. . .
Outside the administration, some lawmakers, policy experts and scholars charge that a bloated NSC staff, filled with what they describe as acolytes who distrust the rest of the government and see protecting the president as their primary job, has helped make Obama’s foreign policy ineffective and risk-averse.

The MH17 Pilot
Click to expand...

i got one word for you. Photoshop. take it from somebody who just closed the program that shot of the "bullet ridden" chair is phooey. if anyone has seen what a 30mm round does to metal you would know it is far more than that. also see how the holes are complete black, even when at different angles, that is a pitch black of a computer rendering. you don't see any insides, or through the holes, again going back to the damage a 30mm cannon would have done. and its also funny how the edges of the "bullet holes" are fuzzy when the other damage to the chair is sharp and clear.

*edit* also look at the direction of the bullet holes, the one up top came from the front. then the ones in the side lower down came from the side to pierce the plane. Unless Ukraine is operating a F22/35 that has that type of vectoring capability those shots would literally be impossible for a plane to pull off, while both planes were flying hundreds of miles an hour in opposite directions.

**edit edit** also that transcript also shows more BS. the rebels just happened to be in the area with AA capability as a Ukraine jet shot down a civilian airliner. They saw this happen, had enough time to coordinate a strike on the military jet (that we have no evidence of whatsoever even with the rebels holding the area) while it was still flying hundreds of miles an hour and somehow both planes landed within roughly the same area?????

You honestly still think a Ukrainian pilot shot down MH17, don't you?

This, despite Russia's veto of a tribunal on the downing. Well, despite all the evidence it has to prove its case, perhaps Russia just wants to protect the Ukrainian pilot in question. One wonders, though, how this Ukrainian pilot got on Russia's good side while Russia holds another Ukrainian pilot illegally for a year for political purposes.
