If they are really Switzerland, the cows would be part of some sinister defence system. :hmm:

It's like a tank, moving cover, only that you can eat it afterwards.:thumbup:

Sure, we use them as radar decoys... :lol:

Sounds like the old joke about mechanized infantry:

What is the biggest threat to mechanized infantry?

The lawn mower - it takes protection, shade and food.

I think I've found one of the most adorably hideous aircraft ever built:

(A heavily modified DHC-5 Buffalo)

What is that thing trying to be?

What is the purpose of amphibious infantry?

To protect the landing boats from small arms fire...

My guess is that it is to test the concept of enhanced lift by forcing air from the bypass fans over the top of the wing. I think there is a Russian-made aircraft in service that uses this principle already.

YOu are indeed correct. That is the NASA/Boeing QSRA, and the Russian plane you are referring to is the Antonov An-72.

I always put the density of Titans atmosphere down to composition (y' know, all that methane), but I just realised that it's over 95% Nitrogen... leaving me a bit confused, as Nitrogen is not heavier than oxygen. So why is that atmosphere so dense, considering the low gravity? do those 4 and something (depending on altitude) percent of methane really have that much impact?

 

[Fabri91]

Might it be due simply to a large amount of gases? If there's just more of a given gas, it should cause higher pressure/density at the "bottom".

Try it with temperature, it is just 93 K, the mean temperature of Mars is 210 K.

Also, the gravity of Titan has a small effect.

Of course, but it seems weird that Titan is able to keep that much gas.

Hmmm... less temperature = slower movement of gas molecules = less gas escaping, is that what you're getting at?

No, simpler also that gas has a much higher density at lower temperatures.

Remember this form of the ideal gas law:

[math]P = \rho R_{specific} T[/math]

If you keep pressure constant, halving the temperature requires twice the density - and the temperature of Titan is about 1/3rd of what it is on Earth, so the density is about three times higher than on Earth at the same pressure: instead of 1.25 kg/m³, it would be 3.75 kg/m³ at the same pressure. This of course also feeds back into the pressure.


And then, the question still is: Why does Titans atmosphere have 19% more mass than Earths atmosphere?

And the lack of solar wind could explain a lot of it, yes. Especially then together with the lower molecular velocity in the stratosphere.

:facepalm:

Right... should have thought of that...

Anyone else looking forward to Paradox's HoI IV? Still kinda sad about East vs West being cancelled though...

 

[Fabri91]

If someone got badly burnt by the last SimCity, take a look at Cities:Skylines. Here some of my mayoral misadventures.

Mars One just released a photo of their spacecraft.

 

[BruceJohnJennerLawso]

To be honest, if I had to rank the Mary Celeste, it would be the farthest one out on both axes

I have HoI III, though between Orbiter and War in the Pacific: Admiral's Edition, no time was left for ole Hearty, so I uninstalled it.

Still got it in the box on the bookshelf, though, and I glance at it once in a while...

Didn't know they were coming out with a fourth model.

LOL that's kind of mean.

I had to search on the WOW signal, that is kind of creepy!

Found out about it a little late, but some information of a certain interest to aviation fans. Hess passed away earlier this month. RIP.

On a separate note, "Battle Hymn" was one of my favorite films as a kid.
