The Space Shuttle does not create a 'sonic boom' when it enters the atmosphere. It is far far far above sonic speed when it enters. So it csn't produce one. And if it would... it would be something like 50 - 60 miles away from your point of observation: no way you ever would hear it.
When it is producing a sonic boom it is already approaching the landing site and probably below 10,000 feet hight and probably less than 5 miles away from the landing site.
Perhaps you should read up 'what' a sonic boom is, and how it is produced.
Hint: stuff that flyes far faster than speed of sound does not produce a sonic boom. Hm... why might that be so...?
We talked about navy Not intercontinental missiles.
And regarding the Russian navy: except for subs carrying nukes they are no threat. They have like 3 or 4 cruisers with cruise missiles, in the black sea. That basically was it.
I'm pretty confident the eventual outcome of a naval fight with the US would favor the US. In a war against Europe/UK? In European waters? Certainly not.
Hints: o there is more Air Force on land then a few carriers have at sea o the US marine is completely unable to detect european subs, except by accident (as in running with a hunter sub by accident into close range of a european one) and, ofc. except for the nuke carrying UK and french subs, they are to big.
The US navy is about the most cartoonishly overpowered military force I can imagine. Most certainly it is. But that does not change the fact that it only can attack European "ground" by being in minimum about 1000nm range. That is the strike range of the Fighters (for very short engagements). If they shoot cruise missiles being farer away, most cruise missiles get shot down by European air defense.
So they need to get the air defense down first.
If they get close enough to engage european air defense, then Europe simply had more fighters than a few carriers can carry. In the unlikely event that they could destroy enough air bases around the coasts, and advance forward: they get sunk by the subs. A single torpedo hit will break a carrier into two parts... it is no longer WWII times.
In waters like the Channel or the Northern Sea, Irish Sea or in probably 50nm - 100nm distance to Scottland, Ireland and Norway the small subs most European countries have are basically undetectable for the US navy.
It is a huge difference if you have a carrier plus battle group to bomb a third world country into the stone age versus actually attacking a region that can defend itself: and has special hardware, to exactly do that, and special tactics to support that.
The UK did not call for the Nato. And unfortunately the NATO treaty territory did not include the Falklands, but I'm certain if the UK had asked for support they had get it.
And the french deactivated the Exocet missiles. Probably it escaped you that all war heads where deactivated and the hits on the UK ships "only" suffered damage from the remaining unburned fuel.
As we talk here about naval stuff, it would suit you to get accustomed with naval units as in nautical mile:D which is significantly "longer" than a land mile.
No, I have not. The russian navy is antique and the chinese not very advanced either. Both have only one single carrier, and the russian carrier has not even a propper support group. And to attack Europe they need to get into range: then we simply think them.
So for a hight of 1000miles, 1600km, one hopp up is 0.02 seconds, one hop down also 0.02 seconds, I doubt the satellites are communicating with each other and transfer a signal to the other side of the planet, if they do, it is like 14,000km distance, which is another 0.3 seconds.
If I was an american strike group, I would not worry about a Russian sub with nukes... The Russian torpedoes are a much much much more serious threat. How many marines on the planet do have torpedoes that go with 350knots under water and have a range of 100nm - 200nm?
Actually it is more or less like that. No idea why you are complaining. Most european weapon projects are joint ventures of various european states and then sold to the other ones. However "standard" destroyers make not much sense. Every few years we design/build a new destroyer or frigg or submarine class. And such a ship/boat is in service for 30 - 50 years. Often it makes no sense to refit the older ships to the new standard. E.g. a modern german frigg is designed to be off shore up to 24month with only the need of resupplying food and fuel. They carry 2 helicopters for surveillance, submarine detection, special ops. Can carry up to 70 men for marine corps operations, via boats or heli. They are designed to support UN/NATO missions all over the planet. They are basically mobile air defense and battle group screening ships, combined with ground attack, small hospital, evacuation etc. options. They are just friggs, but in comparison with a WWII warship they are battle cruisers with a strike range of 200nm, troop carrier and an anti air and anti sub defense platforms. And more or less, that is true for any european frigg or destroyer... albeit the german ones are the most superior ones, obvioulsy;D There is no need to standardize. It is much more efficient to build a state of the art ship when old ones get decommissioned. The only more advanced destroyers and friggs (and that is arguable, because they are special purpose) are the "new" stealth destroyers of the US and the littoral combat ships (but those are quite specialized), and the US will only build a hand full of each of them anyway.
There is no navy on the world, except the US one, that is a thread to the UK's, or any other European navy.
And the US are not a *serious* thread. if they would go rogue and try to attack Europe they need to get their carriers into strike range.
Good bye Nimitzt, good bye Reagan, good bye what ever battle group they bring...
Unlike the US navy most European navies are designed for "home defense"... the chance that a US battle group is able to detect a norwegian, danish, british, german or even greek - for that matt - submarine before half the fleet is dead: ist not ZERO, the chance is not even existing.
Brexit prevents most EU military cooperation so this supply failure seriously weakens British power. BREXIT: UK leaving (perhaps) the EU. Note: this is a political "thing". NATO: UK cooperating with the rest of the NATO. Note: that is a military thing. World Trade: UK is free to purchase what ever they need/want from the EU or from anyone else. Note: that is a trade thing.
I just googled and used http://flug.idealo.de/ to find a flight from Paris to New York City (I believe one way) for 186 EURO, which is aprox. $220
Ofc. that is just the cheapest flight and not tomorrow but in January. And it is not one of the premium air lines, it is "Norwegian Air Shuttle"
Well, with some luck you should always be able to at least get a flight from a major US site to a major European destination.
Berlin <-> New York City with Air Berlin for various dates: 420,- to 465,- Euro. (That is two way!)
Sometimes it makes sense to buy a two way flight, where you only use one of the flights, and have a different flight for the missing leg.
Example: you want to be in Berlin, but your two way flight would cost you $1000 in each direction. Buy a flight + return flight in the opposite direction, from Berlin to JFK/NYC. Obviously you can not fly from Berlin as you are in the USA, so you only use the return flight.
If you really pay 2x$1000 to fly back and forth between NYC and Berlin, it would be nearly cheaper to buy two flights back and forth:D unfortunately it is difficult to "resell" flight legs.
The System.gc() call does not call the garbage collector, it notifies the collector that there is garbage to be collected and the JVM still makes the scheduling decision. a) depends on the VM b) of course it does, otherwise it would not make any sense at all.
the JVM heap size rises independently of the Java allocations so garbage collecting doesn't return heap to the system. Of course it returns heap space. What other kind of space should it return? It does not shrink the size of the heap, though if you mean that. And why should that make sense anyway?
usually forces the collector to check if all the objects still allocated are reachable so the process can be quite inefficient. That is why you don't call it;D but let the memory management system decide. OTOH, if gc() really gets executed, it just behaves like "the real thing". In other words, if you have a generational collector, the standard, it checks only the youngest generations, and it only runs till it decides there is enough free memory... actually it usually does not run at all. It is an anti pattern to call System.gc()... or at least bad style.
I guess under your new ruler that can only worsen. On the other hand, you might prefer to swim to Tokyo e.g. You could even make a stop over in Hawaii on your way, what do you think?
Dude, when I can fly from GERMANY to any destination in the USA back and forth for $350, then it is hard to believe that you pay $1000 from US to Paris.
I go to Paris about twice a month per train for $90 back and forth (but it is only 550km... exactly 3h with a TGV)
If you go to Paris and don't spend quite a lot on food, aren't you rather a moron? After all that is a huge reason to go to Paris to begin with.
Food in Paris is cheap. Probably cheaper than in the rest of Europe if you compare the quality. I'm in Paris about 2x per month for 3 or 4 days. Eating excellent there is much cheaper than in my German "home town" which is Karlsruhe.
I was reading around about 5, more or less self taught, my mother explained the alphabet and after a week I could read. But that did not give me the ability to "memorize" how the stuff is spelled that I was reading.
How often does that happen? My 96GB Wintec FileMate (PCMCIA and USB card) just died a few days ago. With less than 100h of operations. $400 down the trash. (bought it like 5 years ago)

The nuclear missile subs is what really matters, and the Russian Northern Fleet has dozens of them.
And UK has 6, or? And France has 6, too. Or was it 8?
On the other hand it is lucky that the Russian subs are cruising in front of the US and Chinese coast ;D

Shadowed by 2 british, 2 norwegian and 2 german subs, and likely by a US sub, too.
