    Tall Tales

    On my first jump - they threw me out of the airplane with a silkworm and a sewing machine and told me to, "Get busy!". No this isn't a tall tale, that's how it actually happened - really honestly- I mean I wouldn't bullshit you. You should have seen me in freefall - boiling that silkworm and pulling the fibers out of it's ass. Then there was the weaving of the silk and the sewing... I mean, I was a fast learner. When I started jumping - we had to walk to altitude. When it was really windy, we put our canopies on backward, so we wouldn't land backwards. ( I actually had someone tell me this one) When I was bass fishing - I caught one so big it's shadow weighed 10 pounds! Honestly - I mean I wouldn't tell a tall tale. OK I know my post here is a waste of electrons. Truth is - we have all heard the "heroes from yesteryear" tell their baloney stories. Usually I just put on a false look of wonderment and say , "Really, that must have been something.", then walk away.
  2. On this June 5th, I remember Jim Dishroon, WWII Paratrooper, my friend, fellow skydiver who died several years ago. He was one of those brave paratroopers who jumped behind enemy lines on the night before D Day. I think when I knew Jim he weighed about 100 lbs, if that. I don't know his story of what he did after jumping out of the C-47 Dakota, but a friend of mine said Jim once said the "Germans were shooting at us while we were coming down under parachute." Or words to that effect. I jumped a bit with Jim (he didn't jump too often). Jim drove an old Volkswagon (Hmmnn.. never asked him about that), chain smoked, pretty salty guy. He got his JOE (Jumpers Over Eighty) patch and I sewed all of his patches on his parachute container. Sides - flap- everywhere. After he died his son gave me his old helmet, gloves, dirt alert, goggles, etc. He was the real deal. I still have the stuff. Here's to Jim Dishroon. The real deal.

    massis. What is a CTL? So, at your dropzone, there is someone standing next to the arrow all day, every day, manually moving the arrow and holding it in the desired direction?

    US flag made out of F111 material.

    ThighMan. A big problem with "F111 type" material (Harris mills no longer makes actual F-111), is that the darkest red they sell is pale. It looks pretty good on the packing table, but when the sun shines thru - it looks like anemic pink. Also, make sure the blue is very very dark blue. Whatever you have it made of, do yourself a favor and get samples before you have it made to make sure the colors are dark enough to make it look like a real flag - not a wimpy pastel colored one. I would actually suggest NOT making it of that thin material, as the sun shining thru really thin fabric really wimps out the color. If you PM me I can suggest a fabric that is better. A bit heavier, yes, but more opaque for the color presentation. Also, I doubt anyone can embroider the stars that big - and certainly not on material that thin. Usually have to have a heavy adhesive backing to embroider thin stuff. If you want to keep it light, skip the embroidery stars and have white stars by some other means. Please PM me. I might make one for you. Appx 15 x 25 to 16 x 28 range (have to calc the proper proportions) will give you the square footage you want. Skydiving demo flags that are towed are proportioned to be longer than flags flown over buildings. Flags flown over buildings- retrofitted to skydiving - usually look too rectangular. Also, a shorter leading edge is obviously to the skydivers advantage. Small American flags that are retrofitted for skydiver use "casket sized" 5 x 9 dimensions, and not the usual "front porch" flags size of 6 x 8. The 6 x 8's look too rectangular when towed. I have made and flown my own 12 x 24 flag in many demos with "F111 type" (thin nylon cloth for the red and white stripes) for many years. For the 12 foot leading edge It could (should) be longer. If I had it to do over I would change the dimensions and the fabric. PM me if you would like to discuss.

    Toggle fire mechanics

    Timski - you need shorter toggles. Having to lunge up to get them, when time is of the essence, is a tell.
  6. Yeah - the sleeve could have been secured by Velcro.
  7. Yes, I saw one. (Rodriguez rig without hardware for chest and leg straps). It had (pretty sure), flat pieces of smooth aluminum, pretty long, (not plastic) that slid inside of the leg and chest straps. You slid the aluminum insert along until the strap fit you, then folded it back and secured the insert by laying it flat and "locked" it in place with a fabric sleeve of some type, and the sleeve was secured by elastic or friction or something.. (this was 40 years ago) Pretty cool idea - actually. Never saw it jumped, and don't know whether it would have held; but that guy was a thinker and an innovator.
  8. Buy a Mohoc camera. Maybe it's called Mohawk - whatever. t's called - it's about as snag proof as can be mfg.

    "…while state law largely trumps federal law in most contexts..." . Nope. Bad info.

    Who's going to PIA?

    Who is going? One group of attendees are riggers seeking the "Continuing Rigger Education" certificate for attending the required number of hours of rigging related seminars. For starters. Also, riggers who dislike knowledge stagnation in this technological endeavor - known as rigging- who like to keep up with the latest innovations in equipment and who benefit from the knowledge in the seminars.
  12. So Yuri. You'd be a happy customer buying a counterfeit copy of someone's invention. And you see nothing wrong with copying someone else's invention and using for yourself. Wow!
  13. The term "Reverse Engineering" is wordsmithing to cover what it really is: Stealing. If one's intellect and design skills are so poor that they can't make a product of their own...well, I guess they just steal from the guy who did. And to make stolen copies and sell them?...shame on you.
  14. Hookenswoop is correct. The installation must be noted on the data card, the rig re-sealed. Although it can be done that way, it is a very bad practice. This new rigger is now the certifying rigger for this assembly and assumes all responsibilities for it. The new rigger is now responsible for everything inside that reserve pack … and any other defects on/in the rig, because when the new rigger records the info and puts his seal on it, it was that new rigger's responsibility to thoroughly inspect the entire assembly. Including the main parachute if it is still attached. Say the main parachute is installed backwards or a riser is twisted or the main is not airworthy... or there is something about the H/C that makes it not airworthy. If the main was attached when the "just installed the AAD" rigger got it, or the H/C is not airworthy this new rigger has just signed on to take responsibility for everything. Can the new rigger argue that he isn't responsible for all of the other things? Yes. He can argue that. Can the new rigger argue that he is not responsible for inspecting the entire assembly? Yes, he can argue that. "I just installed the AAD. How was I supposed to know the other things were not routed properly or were not airworthy?" Yeah, go ahead with that defense; but not inspecting the entire rig, including the main, if it was attached, is an unethical and whiny and losing argument. Although it is rare, survivors can sue. I'd hate to be in that chair when the fingers are pointed. And even if you beat the legality...I'd hate to be that rigger when other skydivers talk over the campfire about how you gave an unairworthy rig back to the jumper and he went in. All the while you are defensively repeating, "I just put the AAD in and I never looked at anything else...How was I supposed to know all the other stuff wasn't good? etc". Yeah - right. Ethics are just an academic subject, and a rigger's responsibilities are just words; until the consequences fall. Never do this.

    Fingertrapping 550 cord?

    Sheath diameter of 550 cord is too small to eye splice/finger trap 550. I would say that the only way to create a reltively smooth eye splice in 550 is to mimic the usual sewing stitch - the double throw ziig zag stitch. It is used above the "L" bars on parachutes, but only as a back up to the usual clove hitch or double half hitch on the "L" bar. If you use the "joint efficiency" formula in Poynter I, I guess you could use the double throw zig zag stitch using E cord/thread (8.5 lbs) and sew the required number of stitches to equal 550 lbs. 68 or 69 full double throw zig zag stitches. And the zig zag stitches would have to be wide enough to bite into the whole 550 cord - not just the sheath. Just guessing here. Haven't tested that. Works on paper anyway.
