  1. Can I point out again that the pinned posts at the top of many sub-forums are long out of date. They are a distraction at best, and some make the place look really old and abandoned. For example, look at the pinned posts in the swooping and canopy forum. "CP 2014 event master"? "Post your picture threads" (all the threads linked in there haven't had any activity in many years)? Are these and any of the others worth the real estate they take up? In General Skydiving forum: the one on Skyride? Does anyone even remember what that is these days? The "Crowdsourcing" one? The "UPSA role in enforcing aircraft..."?
  2. Another analysis from a pilot and software developer. https://spectrum.ieee.org/aerospace/aviation/how-the-boeing-737-max-disaster-looks-to-a-software-developer
  3. A man goes to the doctor with his wife because she's acting odd, and after a barrage of tests, the doc says: "Well, it's either Alzheimer's or AIDS, and I can't tell which one." The guy says "Well, if you can't tell which one, what's your advice?" "Take her somewhere she's been before, and if she comes back, don't fuck her!"
  4. His explanation for taking the video down is in the first 6 minutes, the rest of the video is answering viewer questions submitted to him. Short answer is that he realized he was speculating about the cause of an accident that was still under investigation. (BTW, I find his videos go just as well at 1.5x speed)
  5. Well, my Google foo must be weakening, as it apparently led me to the 2018 version. So I stand corrected: it is "freefall jumps" now in the SIM (2019 version).
  6. Hmm, I didn't see that. I pulled up the online version of the SIM to check things, so if they did change the requirements, they haven't yet put it into the SIM.
  7. Ha! The latest issue of the Parachutist has a guy under a flaming canopy on the front cover! Apparently done at Z-Hills, so maybe ask them.
  8. Actually, the USPA A License requirement is for "25 jumps", not "25 free fall jumps". The SIM defines a "jump" as a "skydive", which in turn is defined as "The descent of a person to the surface from an aircraft in flight when he or she uses or intends to use a parachute during all or part of that descent." So even if your parachute was deployed before you left the aircraft (only recommended if you are jumping from an hot air balloon), it would still count. (And even if you bounce with all handles in place, it is still a jump (although you would never remember that))
  9. Sex differences in fear of spiders " In the presence of a live spider, women reported more subjective unpleasantness and tension than men and had higher heart rates. Women also displayed greater reluctance to be close to the spider. " Gender and age differences in the prevalence of specific fears and phobias. "Animal phobia had a prevalence of 12.1% in women and 3.3% in men." Arachnophobia researchers want to know why women are more likely to be terrified of spiders Girls are primed to fear spiders "... women are four times more likely to take fright than men..." WHY ARE WE SO AFRAID OF SPIDERS? "About 75% of the people sampled were either mildly or severely afraid of spiders. Of those most were female. (This gender bias in arachnophobia has been supported subsequent research.)" Plenty more if you want to explore
  10. 30,000 ft per min is about 6 miles a minute, or about 360 mph when it hit the ground. I bet the airframe was a complete write-off.
  11. Google translate (in case anyone can help him, although someone probably should just point him to a German Skydiving site). Hello first good morning I am ayman. I also want to learn AFF how to go. Somehow I wanted to make course. I had parachuted jumps with me a couple of times but would rather jump alone. But I'm deaf, I do not know if it works or should not be. But I really want to make affic. Thanks would be nice if it works.
  12. The Fla panhandle would be a bit closer than Myrtle Beach, particularly from P-tree City. Destin or Fort Walton area are nice. It's the Gulf, not a ocean, but same thing, lol.
  13. Actually, if'n youse guys could periodically look in the forums and clear out the spam posts, I'd be happy with any version of the forum software. The sign of the death throes of a forum is when the spam takes over. It's not looking too healthy today.
  14. Particularly because of the larger font display size, it seems to me that getting rid of most of the "pinned" or "sticky" posts at the top of forums would help. On a desktop browser with the old format, I could see about 15 posts, so it was easy to see a lot of recently active posts below them. Now I can see far few, and have to scroll down. For example, in the General Skydiving forum, the "Skyride" post has long since become irrelevant, the "Crowdsources the DZ BS detector" was never (IMO) of any importance anyway, and god only knows why "USPA's role in enforcing aircraft maintenance issues (was - Incidents thread)" was ever pinned in the first place. IMO, clearing out some of this detritus would help.
  15. OTHO, the defendant likely would be the DZ, who would know plenty of "friendly" experts they could call on, so they would be unlikely to be sending out cold-call emails to find someone. I think this is almost certainly from a potential plaintiff's attorney.
  16. Q: What's the best way to ensure that your Baptist fishing buddy won't drink all your beer on a fishing trip? A: invite along another Baptist.
  17. Just mooing is okay. (At least this: https://www.youtube.com/watch?v=mXnJqYwebF8)
  18. Maybe because dishonestly doesent come off as natural to everyone? T From my perspective it is called being a professional. I will not let any video out that does not hit my quality standards period, I would rather refund the money than put out a product I wasn't proud of. I personally wonder if he just gave it to the student and went on about his day, rather than bring it to the attention of the DZO and then the S&TA or DZO take appropriate action on retraining the instructor What was wrong with the quality of the video? Nothing as far as I can see. What *might* have been "wrong" is the technique of the TI revealed in the video (although we really need to wait for ChrisD2.0 to weigh in on that before we can be sure
  19. Well, about 21% of air is indeed oxygen, so strictly speaking that DZ was correct, oxygen does come out of the air vents. Our dropzone runs a 78% Nitrogen blend. The larger molecules are less subject to temperature related expansion and contraction. Air (dry) is already 78% nitrogen (and 1% argon, 21% oxygen). Each component follows the ideal gas law under any reasonable skydiving condition; molecular size is essentially irrelevant.
  20. Idiot brings a tire iron to a fist fight: https://twitter.com/RealJamesWoods/status/1065482164022571008?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1065482164022571008&ref_url=https%3A%2F%2Fs9e.github.io%2Fiframe%2Ftwitter.min.html%231065482164022571008
  21. The way to get more people to sign up to be organ donors is to pass a law that you cannot be the recipient of a donated organ unless you can prove that you previously agreed to be an organ donor (and that you did so at least 2 years before you needed an organ). (Maybe couple that with a law that prevents heirs from overriding your choice to be a donor.)

  23. Folks, Be extremely cautious about relying on anything ChrisD2.0 says. ... [SNIP] The end of ChrisD (1.0): http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=4581656 So beware. I borked the link in my post above: I fixed it now in this post. (http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=4581656)
  24. ChrisD2.0 doesn't need to provide evidence. He is the knowledgeable authoritative expert on virtually everything. If he says it, you can bet it's true. Just check his posts on *every* topic in *every* forum here. And also the posts he made as ChrisD years ago (The end of ChrisD (1.0): http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=4581656 )
  25. That ChrisD2.0! He knows everything about everything!
