Yes, because isolating a country due to their negative aspects breeds tolerance in their youth.
Or perhaps the internet, with its ability to expose people to other cultures and view points; allows for people to broaden their thought process beyond the otherwise dictate thought process imposed on them.
Take Iran's huge success lately in broadcasting their opposition against the government. Or the use of BBS and other internet based sites to communicate with each other to plan rallies/protests.
Yes, let's do away with the one universal asset that can be shared with the world to assist, even indirectly; in introducing new thoughts and enlightenment.

"indicated releasing sea water that is held inside the tubes"
"ballast" does indicate a weight keeping a ship or object submerged"
You don't say, clearly I missed that and didn't articulate that point.

And here I thought in submarine movies the term, "blow the ballast tubes" indicated releasing sea water that is held inside the tubes to allow for bouyancy. Hence, allowing for a sharp decrease in depth. So yes, while "ballast" does indicate a weight keeping a ship or object submerged, it can also be used as a "ballast tube" that causes lift.

Someone who believes that pollution reduction should be mandatory is a crazed activist? I think I'll side with the "crazed activist" who never stated what kind of programs he had in mind. Rather than you being my other option, the overly dramatic nut job that thinks the pretty sunsets over industry cities are just enhanced scenery. I'm mean, if we're throwing around blind accusations, that IS accurate no?

10% slower for 70% fuel decrease on a 737? Unlikely.

..three times. I have gone to doctors over a span of years who have never correctly diagnosed a few issues I have. Always saying it's one thing or another. Well, over the last five years I've diagnosed, presented and suggested treatments for each issue to my present doctor. I have hyperhydrosis of the palms. It's not severe, but it definitely makes shaking hands or trying to open a pickle jar problematic. I had a GP who had never seen this type of issue before, and wanted to schedule me for specialist sessions with both a neurologist and a dermatologist. I told him to let me think about it as I was living paycheck to paycheck at the time, and had cobra health care that wouldn't cover it. Fifteen minutes of searching online gave me an answer to what the issue was. To which I presented to the GP, he looked up, and verified. Which subsequently answered my next problem, dyshidrotic eczema; which randomly affects my hands. Again, not in a severe manner, and isn't noticable unless I were to point it out, but something my GP couldn't identify himself. In the end, both of these were caused by a third issue, an allergic reaction to certain metals in my diet. For each of the issues Google was able to identify, diagnose, and offer treatment plans for. All of which my GP researched after being presented with and acknowledged. If I had gone to the specialists would I have been diagnosed correctly? I'm sure I would have. So does this mean I am as well versed as a specialist over a standard GP? No. But it certainly has saved me cash along the way.
