if you have a motorboat that will go 10 MPH at 1500 RPM, and put it in a 10 MPH current, the boat knows nothing of that current. It only knows the water around it. It is now traveling 20 MPH over the earth, but it is operating in the ocean.
Same goes for a plane in flight. It operates in a "sea of air". It knows not nor cares not for wind speed over the ground, till you get to the ground and try and transition to the tires Smile
Transitioning through the different speeds of jetstream to the core is a bumpy proposition. As you move from one "river" of speed to another, the plane passes through a shear zone.

I see what you are saying but I am still a bit confused on this. I know that you can treat air like a fluid mathematically but I don't see how this analogy applies to what I was talking about. A boat's ability to float has nothing to do with the water current beneath it whereas plane's ability to stay aloft has everything to do with the air current over the wings. I was asking about stall speeds at cruise altitude.

I realize that the plane itself knows of only the air around it but if you are going 500 mph (and 500 mph ground speed) with no wind, the plane sees a 500 mph flow over the airfoil. If there is a 150 mph tailwind, the plane still has a 500 mph ground speed, but the air around it should be 350 mph (which was your boat analogy). However, where your analogy missed for me is that there is no minimum speed where the boat sinks (which is what I was asking about). My question was not about what the plane sees per se but rather what the airfoil sees. If it "sees" 350 mph over the airfoil (instead of 500), the lift will be what it is at 350 (whatever that may be). So what I was getting at is that if you have a tailwind that strong (like 150 mph strong) and you are cruising at 30,000+ feet where your stall speed is much higher than at 10,000, couldn't an air current of that strength cause you to lose enough lift to where you may stall?

BTW, I am just picking the 500 because I have flown over the pole many times going to Asia and they are typically going around 600 so I just used 500 for easier visualization. (That Polar Vortex can be rough) I also only recall ever seeing a max tailwind of 60 and that just made me think of the question of at what speed is too much to where the pilot would just avoid that area.

RE: Ranting corner
The plane cares not about the ground. It flies in air. It knows not where the air is going or how fast. What you are describing as a problem would only happen if the air mass suddenly said "stop, hammer time" and started break dancing Smile
forget about the boat floating thing, sorry that confused you. It was all about that sea of air. It changes direction and speed but not at such a rate that the plane just falls out of the sky, except in the case of the microburst. It takes an interaction with the ground to produce an effect strong enough. Up in the atmosphere the worst of it will just bounce your head off the overhead compartments if you are not belted in.
Besides, stalling is over rated. Planes stall all the time in severe turbulence. Then they un-stall a few milliseconds later. That's the bump.

RE: Ranting corner
OK, let's look at it one more way. We are speeding along at 1000 MPH due to the Earth's rotation, and the Earth itself is moving at 30 kilometers a second in the orbit around the sun.
The galaxies in our neighborhood are also rushing at a speed of nearly 1,000 kilometers per second towards a structure called the Great Attractor, a region of space roughly 150 million light-years (one light year is about six trillion miles) away from us.
Do you feel any of that speed? No, because your point of reference is the earth. The plane's point of reference with regards to lift and drag, is the mass of air it flies in.

And while I’m dropping by the ranting thread, I might as well: if I hear the phrase “creation of the universe” one more time while watching otherwise excellent documentaries, I’m gonna throw something at the computer.

Other than this (and he didn’t write it anyway), Jim Al-Khalili (who, as it happens, was head of the British Humanist Association until very recently) is fast becoming my favourite documentary presenter (and not just because Brian Cox’s last series sucked BIG time). His Secrets of Quantum Physics, Chemistry: a Volatile History, Order & Disorder, Light & Darkness, Everything & Nothing and The Beginning and End of the Universe are all excellent and wonderfully presented Heart

Would not be shocked if it were real; I considered going to a parish men's group recently to try and meet people. Then I saw that they're doing "spiritual warfare" with copies of the Eternal Word Television Network (EWTN) show "Crossing the Goal". A sports themed thing where I could totally envisage someone wearing that shirt...

Need to think of a witty signature.

It’s a direct quote from that musical and poetic masterpiece of a song, Dropkick me, Jesus, so it very well may be real.

Well, there’s Christian wrestling, so I can’t say that surprised me too much (though I tried watching a bit and it was cringe-worthy). This, on the other, kinda did surprise me… Blink

Title: Undefeated
We should realize that Jesus willingly fights and intercedes on our behalf. We should remember as our efforts to help others go largely overlooked and unappreciated, so also do the manifold works of God. To see our Savior as Undefeated is no simple task. As we are battered and knocked down so often in this short but intense life, we may secretly wonder about the power of God. Why would a loving Father let us suffer so? Why should we be put in the ring with forces greater than us? If we count the earthly cost of Jesus' divine qualities, we see He bears the scars of many previous battles, most of which are unknown to us. Perhaps then our scars can be put in perspective. Would Jesus have the compassion needed to forgive and have mercy on us had he not suffered as we too must suffer? Did living the life of a mortal add to His infinite abilities to understand the frailties of His children? Indeed it is so. Not only did Jesus willingly allow those things to happen to Himself but He also allows them to happen to us. In the presence of man's arrogance, to destroy that which is spiritually superior to him, Jesus suffered more than we will ever know. Let us choose to be in the ring, to fight the good fight of faith, and be grateful that we are in the same corner with the Undefeated one. Regardless of how humility is scorned as weakness by the ungodly, one scar, in the true unselfish and humble service of Christ, is greater than all the crowns made for all the kings of the world

[Image: warfare.jpg?format=1000w]

Title: Warfare
The battle for our eternal destiny was never intended to be easy. It is only in our daily moment to moment free will choices that we achieve victory over our human nature. And once our flesh has experienced a taste of the divine reality our most difficult struggles begin. Our urge to avoid God must always be mirrored in front of our need to serve God by loving man and serve man by loving God. Having once felt the joys of eternal life in our veins there is no recourse but to face the struggle that taunts us even as we sleep. And finally having made the choice to rise from the ashes of our self-destructive tendencies we experience the mortal version of the resurrection of our souls by sensing God's joyous approval in our hearts and we know what must be done. We know that it doesn't matter how many times we fail. We know it doesn't matter how many times we are ashamed of our past. We know once and for all the only thing that really matters is that we have made the final and irrevocable consecrated free-will choice to forever be a child of God, scars and all. Our will must be dedicated to doing the will of our Father and serving others as Jesus served and continues to serve us. We must rise up. We must succeed. We must truly become alive and breathe the air of spiritual truth, beauty, and goodness. At the same time we must also know we work in the presence of the same moral decay and darkness that swallows every good seed that can only live anew in the light of God by its very death. "Warfare" is dedicated to my struggle and the struggles of every person who says "Yes" to God regardless of the battles and regardless of the price.

And then I asked myself what is this obsession with religion and sports over there, and came across this.

"For far too long, lamented Thomas Wentworth Higginson in 1858, “the saints have been ‘ashamed of their bodies.’”For Higginson, Christians had failed to realize the interconnectedness between body and spirit. Christians needed something more physically robust. And as it so happened, America’s bourgeoning physical culture movement was ideal. Noting development of a certain social trend in the early Victorian period, one scholar described the movement as “a tradition which celebrated the Christian gentleman as vigorous, athletic, and manly.” With the “cult of sport and games” in the late-19th and early 20th centuries, this scholar wrote, such “Muscular Christianity” was seen “as a needed corrective to the feminine influence in religion.” Simply put, there were too many women and not enough men in church. Christianity needed more masculine appeal, and physical culture provided. The point? Christians popularized physical culture and sports in America, and they did so by critiquing the fragility of women and the pervasive problem of womanly ways."

Okay, I'm done now. I’ll show myself out. Confused

RE: Ranting corner
I know i'm going off the current topic of Jesus related sport paraphernalia but i didn't know where else to put this

Who and how the fuck did a match up between socialistviews and theborg occur how did we manage a throw down between a word salad generator given life and the definition of delusional made manifest .And wanna no even harder is why aren't we trying for more of this seriously matching up this sites lunatics would be freaking awesome we could have.

Tomasia cs Call Of The Wild they could exchange insults accusations and never get around to having a fucking point

We could put Thedarkone up against his own sense of victim hood

and KerimF up against a glass of warm cola (i betting on the cola)
