An ad for a Soviet Bomber, with the description in Comic Sans, followed by a verbatim dump of the TU-95MS Wikipedia page. But the seller has an excellent rating, so it's probably legit.
welcome to bitcoin.
- Seller writes "u" and "dissamble" in "We can therefore dissamble the Plane so u can get one or all of the turbines exclusively" - Price tag of US $3,000,000. Well, I'm convinced. Here is my credit card!

when Tu-95 were flying out on patrol in Atlantic, the US underwater listening stations (for submarines) installed on the Greenland-Iceland-Norway line were registering the planes too.
The TU-95 is probably the loudest vehicle ever built that wasn't rocket powered. The prop tips are well into the supersonic range.
I've yet to come across any firm proof that the Bear has supersonic tip speeds, even the wiki article says "according to one media source".
Now obviously with any prop aircraft you can generate a scenario where the tips go supersonic, but I feel "The prop tips are well into the supersonic range" is a disingenuous statement. I do agree with you in general principle though - tips can, and do, go supersonic.
Some back-of-the-napkin calculations for the Bear, using the figures given by the media source on wikipedia: 5.7m prop diameter 750rpm at cruise
Circumference = pi*diameter = 18m 750rpm = 12.5 rotations a second
Giving a tip speed of 220m/s, so contrary to the media source the blades are not supersonic by themselves.
You could, of course, engineer a scenario where the combination of the airflow through the prop + the prop tip speed > mach. But you can do that with a Boeing Stearman too, you just avoid it by design due to the increase in drag, and not to mention the stress placed on prop blade that is subsonic at the root, transonic in the middle, and supersonic at the tip.
I've seen people give the noise created by the Bear as evidence of supersonic blades, but I'd put that down to interactions between the contra-rotating props, a bit like blade slap on a helo.
Now the Republic Thunderstreak is an interesting story - a plane with (proven) supersonic blades: http://www.youtube.com/watch?v=UFhSzReWTgs

To be fair, there are many reasons why North Korea was left alone while Iraq was considered "safer" to invade. Seoul being with range of massive amounts of North Korean artillery is one. The concern of both China and South Korea about the potential for floods of refugees is another.
> To be fair, there are many reasons why North Korea was left alone while Iraq was considered "safer" to invade. Many reasons why Iraq was considered more important to invaded, and all of those reasons are "barrels of oil", as elucidated in 2003 by then-Deputy Secretary of Defense Paul Wolfowitz: "Look, the primarily [sic] difference -- to put it a little too simply -- between North Korea and Iraq is that we had virt…
If you're claiming the U.S. would be likely to invade North Korea if they had significant oil reserves, that's wrong. As Wolfowitz says in the context around your quote:
The concern about implosion is not primarily at all a matter of the weapons that North Korea has, but a fear particularly by South Korea and also to some extent China of what the larger implications are for them of having 20 million people on their borders in a state of potential collapse and anarchy.
...
In the case of North Korea, the country is teetering on the edge of economic collapse and that I believe is a major point of leverage whereas the military picture with North Korea is very different from that with Iraq. The problems in both cases have some similarities but the solutions have got to be tailored to the circumstances which are very different.
Hard to draw from this that the "only" reason invading Iraq was more important was oil. The lack of economic leverage made a military option relatively more practical, as did the military and social situation of Iraq vis a vis its neighbors.
It took me only a few seconds to find on Google Maps: https://maps.google.com/maps?ll=46.921164,32.083704&spn=0.00... Looks like it has a few siblings, so what you're getting is not as exclusive as you might think... That explains the pictures on the eBay auction appearing to be from different fuselages - they actually are (the two rightmost ones on Google Maps). EDIT: Hmmm, maybe not. Perhaps it's the same plane in…

> there is a TU variant with swept wings, var geometry, and jet engines that replaced this plane that most Russian republics use "Most Russian republics"? So, more than half of the 1? And "Tu" is just an abbreviation for Tupolev, its not a particular plane of which there are variants. Saying a "TU variant" is like saying a Boeing variant. And there are two different Tupolev strategic bombers that meet that general de…

So, name the 11 that have militaries that employ the bombers in question.

On a tangent, how much do you notice the political tensions in your everyday life? I read some accounts by people from Odessa who said they didn't bother much and saw as their first priority that nobody died no matter on what side. Are you still far enough away from the Crimea to ignore everything if you chose to do so? Also I'm wondering if people will give you strange looks exporting a 4-engine military aircraft ou…
We're almost bordering Crimea, but Crimea is an autonomy, so what happens there is more or less confined. You can ignore politics here if you choose to do so, but unfortunately you can't ignore economic repercussions of it. Exchange rates are skyrocketing, prices on import products (majority of them) rise accordingly, banks put limits on access to debit cards and extreme limits on credit cards. In our biggest bank yo…
Evgenuiz;
Are you, or have you news, if bitcoin, or other e-currency, is being used, becoming popular as an alternative to your "...you literally can't spend more than $20 per day from credit card", etc?
