Nice!.... they probably should go ahead and change that light bulb while they're up there.

Hmmmm ...another "meeting" with "muslim leaders" and yet another capitulation. I guess that sometimes you just get an offer so fair and reasonable that you can't refuse it.

Sweet! ....is this a new PBS series by Carl Sagan's younger, hipper brother?

Well.... "Yankees" come down here, spend all their money and go home. "Damn Yankees" come down here and stay. They spend most of their time telling us how they do things up north and the rest of their time bitching about the heat and the leaves not "changing" (whatever the hell that means!)

I haven't heard a lot of protests from ministers against the Westboro Baptist Church, and they're definitely still around. I guess that Christians are for that, then, right? What makes you think that the opinion of moderate Muslims in the US will make any difference whatsoever to radical right-wing Muslims in Afghanistan and Pakistan? Wendy P. Holy crap! ....Did WBC finally start blowing stuff up and lopping heads off? I knew those nutcases were close to the edge!

Perhaps you should examine your motivation to begin a risky sport at this particular time. A little introspection for 2-3 months (at least until football season is over) could be very helpful. .....just sayin'. Just kidding! of course! Welcome to the sky!

Well.... the ones that weren't gassed. You know, ... the ones that say things were much better under S.H. Ya can't make everybody happy. Perhaps they should have drove their darned cars. I suppose you can make everyone happy if you could just exterminate all the debbie-downers.

[reply.......... Of course, opinions vary. In SA, women are not allowed to drive cars or work as educators beyond the secondary school level. In Iraq, before the war, women could drive cars and be educated at a university level. Well.... the ones that weren't gassed. You know, ... the ones that say things were much better under S.H.

Ok, which is it? "two" or "three" ? Smartass! Hey, that fits me perfect. Yeah, I'm Smartass. Hey! .....the rule says no combining words to make one!

"....the most elaborate hoax in our nation's history,......" Well, that's a stretch! I think it might beat the moon landing but if you compare it against the entire manned space program it comes in a distant 2nd. ........3rd if you include the WWE in the list.

Uh....Look inside the shell!

"You bet your sweet ass.......!" :)

Congrats on your survival! But.... you got that one out of the way...... more to follow.

Go get yourself some booties.

Go get yourself some booties.

It should be an offense to practice physics or engineering without a license. Lift is DEFINED as the component of force perpendicular to the free-stream vector. If you are tracking, you must be generating lift. Points I was trying to make: 1) Tracking does not "generate" a significant amount of lift. Some people can track at better than a 1:1 glide ratio. That requires a significant amount of lift. For someone with a 200 pound exit weight, the lift needed for 1:1 is over 140 pounds. Also the vertical descent rate of a GOOD tracker can be below 80mph in a flat track (see previous link), which is a SIGNIFICANT decrease from a nominal 120mph freefall. Now that is impressive! That tracking dive (in your link) seems to have resulted in a horizontal speed (over the ground) of 93 mph (based on 77.5 mph vertical rate of descent) in a RW suit! It works out to 1.2:1 glide ratio and he had an actual airspeed of about 121 mph.! I stand corrected!

You can believe what you want. I however, have data. Stable belly to earth for me is around 118-120mph vertical. In a good track, I consistently get down to high 80s to low 90s. On a good day, I'll get it as low as 85mph or so, which I've done on several occasions. That's about 20-25% reduction in descent rate, which is significant. Well, you seem to have answered my last "question" in that post. You have provided data, I have no reason to disbelieve it, and my mind is changed about that. Thanks!

You still haven't shown me how I misread your post over on the poison egg thread.

[reply...............I agree that de-arching and cupping your shoulders, straighten legs, arms close to your side, etc. are ingredients for a good track. However, I don't believe you are significantly decreasing your vertical descent rate.... nor are you "generating" a significant amount of "lift" of the Bernoulli persuasion...... It should be an offense to practice physics or engineering without a license. Lift is DEFINED as the component of force perpendicular to the free-stream vector. If you are tracking, you must be generating lift. Points I was trying to make: 1) Tracking does not "generate" a significant amount of lift. 2) A very insignificant amount of lift is generated by the differences in pressure above and below your body because of the (usually misapplied) "Bernoulli effect" by trying to shape your body into an airfoil. 3) A somewhat less insignificant (or more significant) amount of lift is generated by your body's angle of attack. 4) No matter how well you think you can track you are not making as much headway as you think you are compared to the altitude you are using up. The point I was trying to make is that making your body rigid and tweaking your angle of attack has more effect than trying to assume an un-clean, low aspect ratio airplane wing shape.

Yes. Let's ague semantics when the guy wants to know how to track well. Lift doesn't mean I go up relative to the ground. However you want to explain it, a good track has a significantly slower descent rate than your best slowfall position. No matter what term you want to use to describe it, there is additional upward force being created by a good track when compared to other body positions and tweaking the position to give better forward speed somehow seems to also create slower descent rates. A flat body position does not give you a great track. It'll get you away, but you can do much better and in some circumstances, much better is what is expected. A really good track needs some de-arching through the body and shoulders. I agree that de-arching and cupping your shoulders, straighten legs, arms close to your side, etc. are ingredients for a good track. However, I don't believe you are significantly decreasing your vertical descent rate.... nor are you "generating" a significant amount of "lift" of the Bernoulli persuasion..... maybe just a little because of your "angle of attack". You are increasing your "absolute" airspeed. Kinda like how a tacking sailboat can go faster than the wind. Or, like a downhill skier you are "sliding" down the hill when you are tracking and your increased airspeed is derived from the downward vector and the translational vector, but mostly from decreased cross-section in the direction of travel. That was all intuitive guessing on my part but my mind can be changed by looking at some numbers.... maybe from a recording altimeter like a Dytter or something.

Not condoning it in any way. But people in your and my countries feel differently about animals that are not cute and furry. Real Veal, or Lamb for instance. You all might want to check out “KID” Leather production too while your all up on your soap boxes., We treat many animals with extreme cruelty, but only seem to wail about the cute and furry ones. I think kangaroos are cute but I like my kangaroo-skin boots.

I'm pretty sure that neither of those guys is illiterate. Again, a GWB fan? The question is, is our children learning? Nope....... not a "fan". Not in the same sense that you're a BHO "fan". I see, just an emulation of GWB; my bad. Yes! That's it!

I'm pretty sure that neither of those guys is illiterate. Claiming that W is illiterate might diminish any otherwise legitimate arguments you may have against him. Obviously, his public speaking skills are not as polished as we expect our leaders' to be.
