    Brother, I GAVE you the NASA information. I have to assume you didn't read it. I did read her code. She merely used NASA's data to derive her own resultset. If I take your Aunt Mary's recipe for BBQ sauce and change one ingredient; is it still Aunt Mary's BBQ sauce or my use of Aunt Mary's data to derive my own while pointing at Aunt Mary's recipe as the foundation for my result. Ron posts some Pete "Something" video that an engineer friend of his sent him. The Pete "Something" is a Market Analyst. That means he has something to sell. Pho Is a stay at home mom who thinks her degrees in economics and finance give her some insight as to interpreting or arguing against science. "Kallend fell into this trap." You know; Kallend, Bill and and I may have differing philosophies on social issues, but they probably have more experience in science than most people on the planet and rather than even attempting to learn from them; you and Ron throw hacks at them as uncontroversial evidence that they're wrong. Brother, that is just plain silly.

    Same idea in racecar driving and extreme driving training. You have to learn how to put the car into skid and manage it so as, beside safety protocols, it provides an entire new range of driving methods and performance capabilities. When you're keeping the car hair breadth from the skid, that's when you're taking track bends the fastest; for the speed turns/ maneuvers you have to initiate an actual skid and control the car while in it; you activate ABS by precipitous braking and learn to maneuver under it etc. etc. - a broad array of inputs, techniques, and respective results. There's various special equipment and drills to imitate both intentional and unintentional situations, activated either by the student or the instructor or both, depending on the exercise. And you drill it so much that your knees, elbows, and shoulders are continuously bruised because of the kicks and the G's (right hand side ones if you're doing track), hands scuffed and blistered even with the gloves, letting alone your crippled neck, head and eardrums at the end of the day. Same principle, same method: you do the "error" and learn to control it. Another important notion is: these "errors" can be, and often are, easily and imperceptibly entered into by doing nothing conscious, simply through unawareness or/ and lack of attention. That's exactly why one needs to know by rote where the "mistakes" begin so as you can keep your focus on preventing them when such is your current intent.

    Hallelujah. As to the need for fear/ real experience vs. talks, studies, and even "letting them see the negative outcomes", there's a number of massive plain examples. One of them would be the improbably high crash rate that occurred when one very large Asian country experienced rapid economic growth and its dwellers started becoming first-generation car drivers en masse. A big expensive analysis showed that most of them never expected the car crash to be so painful & encumbered with consequences because they knew driving by playing computer games. This is not even an anecdote, the data on this research is publicly available. Another much sadder one is the historical fact of the widespread public enthusiasm upon declaration of the civil war in another big country. To be compared with the general sentiment upon a few years into the war on its both sides. Repeated multiple times through ages. Same reasons as why "peaceful citizens" can never fathom those in the war zones nor veterans coming home, and don't let me start on some of them who are aggressively pushing their rights or promoting their informed views. From this angle, the conclusions look straight, one would hope.

    Topography, traffic volumes and money dictate most road construction contracts. With certain exceptions of course.. Then you factor in environmental issues like rainfall, snow, animal corridors, nearby urban areas, etc. Thats why a lawyer stated “That would be data that would put that cities on notice that it’s a dangerous stretch of roadway,’’ Shouse, who now runs his own law firm, told USA TODAY Sports. “And their failure to take reasonable steps to alleviate that danger, to either redesign the roadway or add a traffic signal, reduce the speed limit, add speed bumps, take various measures to reduce the risk, their failure to do that could potentially subject them to liability.’’ What he forgot to mention is that the speed limit on that road is 45 mph. Now if you're on some sort of crotch rocket with the stickiest widest track tires. Perhaps you can negotiate that road at one sheriff's deputy said he's clocked cars going as fast at 80 mph.. But the laws of physics take president over inattention, stupidity and bravado. As you know those factors can all act to separate a biker from his ride.

    Unfortunately in many cases we just have to wait for older racists to die off and rely on the newer generations to do better.

    Except that if the road is an accident trap, is that privilege being used to better things, like adding one more (louder) voice to the chorus? Wendy P.

    No better example of class privilege right there.

    Yes. It's a subtle but important distinction that the 'bad behavior' isn't being taught. It's the 'how to get out of trouble when you end up in it' and 'where the edge of trouble is' that is being taught.

    Pratt&Whitney spent more than 20 years developing the GTF - geared turbofan - because it was a big improvement in fuel efficiency, by removing the requirement that the compressor run at the exact same RPM as the turbine. So a hybrid aircraft design could optimise its turbine for generating electricity, because electric motors can then easily rotate at any RPM needed by the aircraft, and batteries could buffer the variation in power needed. Whether a hybrid has an overall increased weight is to be determined - there are too many factors to determine right now, but hybrids will probably be more feasible with larger aircraft, and smaller aircraft will probably be more suited to full electric. CO2 is only one reason for going electric. The operations and maintenance savings are potentially massive - so if hybrids improve this, even if not as good as full electric, the market will adopt it. (Which is why Airbus is investigating hybrids right now)

    She also lists "Mrs. Smarty Pants" as one of her qualifications. Can't argue with that!

    When I went through the training, there were two reactions: "We have to take the truck out there and do skids? Oh my god!" "We get to take the truck out there and do doughnuts? WOOO HOOOOO!!!!!!" (I was in the latter category).

    i went through a skid pad once. that was a blast. almost as good as the real thing when i topped a hill once and encountered some ice. i saw a landair trailer in my mirror and it took a second to realize it was mine.

    Fear can be a training tool, but it must be used wisely. Too many early skydiving instructors came from the military where fear is routinely used to prepare soldiers for the ridiculous levels of fear and confusion they will face in combat. Military instructors gradually ramp up fear to further condition young soldiers. They also use fear as a selection process to determine which soldiers can tolerate the highest levels of fear and uncertainty. Young soldiers with low tolerance for fear and uncertainty become cooks and drives, while those with high tolerance become special forces door kickers. Unfortunately, some military instructors miss-interpret this use of fear - as a teaching tool - as a license to act like bullies or jerks. Fear does not work well as a training tool for civilians who have never been in a life-and-death scenario before. They get over-loaded and freeze. So civilian skydiving instructors need to know when they can apply pressure and when they must back-off to avoid over-loading students. For that reason, I use a minimum of fear when teaching the first solo jump course and emphasis what a good main parachute and good landing approach look like. We can add more levels of complexity (practicing stalls, riser turns, etc.) during later jumps.

    Agreeing with Gerry Baumchen, The first freebags had no through loops (e.g. Strong Dual Hawk Tandem) and short closing loops were tied to internal flaps. Second generation freebags had through loops, but they still rubbed against reserve fabric (e.g. Talon 1 and all Vectors). loop length varies widely depending up the rigger's experience. I have only sewn patches on two reserves, but one of them was in a NARO. The reserve center cell suffered a small tear because a rigger used more muscle than skill in pulling the closing loop through the free bag. Even if I only have to patch one reserve every 1500 repacks, that is too often. Third generation free bags are pinched in the middle they are easier to with only a single grommet through both layers of the freebag (Javelin, Talon 2). They are easier to pack because they need fewer tools and have a consistent loop length. While working at Para-Phernalia, I managed to convince them to switch Softie free bags from second generation to third generation freebags. EOS, Atom and Icon are between second and third generation in that they have grommets in both the top and bottom skins of the free bag, but they also have fabric channels preventing the closing loop from ever rubbing against on reserve fabric. Fourth generation free bags have more secure lines stows to properly stage higher speed openings (Icon, Racer Speed bag). These are mostly found on tandem and military rigs that deploy much heavier and faster than solo rigs. If you have read this far, you understand why I clearly prefer third generation free bags.

    Hi 93, OK, you asked. ParaFlite was the first to have a 'channel' from the bottom grommet to the top grommet to seperate the closing loop. They also had a small piece of plastic pipe in the 'channel' to keep the 'channel' from being squished. Not long after, I added the 'channel' to my d-bags. I did not include the piece of plastic pipe as I considered it unnecessary. I just never liked the Vector method of using another piece of line with that slip knot in it. Too much extra work IMO. And, do not get me started on 'rigger friendly' about the Jav's 'pinched' grommets. I'm admittedly biased, but the 'channel' is the best design for the rigger. Jerry Baumchen

    I'm going to have to call bullshit. All men have been carried by a woman. They're called, "Mom."

    Hereby proving that you don't read what people wrote. The military itself admitting that systemic disparities in how different races are treated exist within its institutions, including its internal justice system, cannot possibly be defined as any kind of exception. Sure they're trying. But they quite obviously have not yet come close to fully succeeding. And while the everyday experience of life in the Army is not yet the same for black and white soldiers across the board, the claim that the only colour in the Army is green is insane.
