  1. if you made a rib bias constructed, it would have to be made out of 2 or more pices of fabric. a bolt of fabric is only something like 60 -65 '' wide. take a rib that is 10 feet long and then lay it across the fabric on the bias and you will see wahat i mean. early strong tandem mains actually were (are) bias constructed ribs.
  2. thats because para flite invented it Elek Puskas was the patent holder.
  3. the nb6/nb8 was a pilot emergency parachute,intended only for emergency escape from an aircraft in distress .there were no d rings to attach a reserve because it(the nb6/nb8) WAS a reserve so to speak."Sport Jumpers " as you put it , are making intentional jumps from aircraft and use a main parachute AND a reserve which,would require a set of d rings on the front of the harness to attach a chest reserve(Unless you are using a piggy back which is a rig specifically made for sport jumping. on a piggy back(or tandem as they used to be called)the main and reserve are both on the back.) the chest packs were equally useless as they did not have their own harness. personally if cooper was jumper it would make more sense to me for him to have used the sport main because it had" d " rings on the harness.
  4. "if the main fails he's gotta cutaway".... ummm the nb6/nb8 harness container does NOT have canopy releases, so not an option ..
  5. Joe Smith,theres a name i havent heard in eons.
  6. i understand there was a directive from GQ security years and years ago that basically said all their products 20 years and older were to be taken out of service,or something to that effect. can someone post it for me . no its not anything to do with the acid mesh debacle.
  7. must be someone who worked for Steve Snyder!!!!LOL
  8. I remember Dave very well. back in 1963 or 64 he landed on my dads property(adjacent to the dz) and broke his ankle. Dad was so upset,because he thought he was gonna be sued by one of them crazy skydivers.get well Dave!

    the military version had a microchip in it so ,it actually was a "smart' aad.there were many problems w/the chips right from the beginning,.
  10. it all depends on the "blue ball factor"'
  11. interesting post. you also bring up a point i hadnt thought of "suppose he got both chutes out?" that would drastically affet his drift and throw his probable landing zone off.
  12. it is true. any pioneer 3 or 4 pin sport container i have seen has that marking on the bottom flap.it always struck me as odd because the markings were not required per se, but i guess pioneer wanted to cover their butts. if any of you old timers have seen a pioneer 28' LoPo main from the 60's, you would also note that pioneer marked those as TSO C23b.odd for a main parachute,since it wasnt required.(never saw it on a para-commander that i can recall tho)
  13. Gas was cheap back then and you could drive to seattle and back for less than $18.how far is to seattle? gas back then was about $.29 a gallon or thereabouts
  14. maybe he chose the nb6 over the pioneer sport rig because the pioneer rig would have been stamped(on the botton flap in inch and a half red letters) LOW SPEED PARACHUTE LIMITED TO USE IN AIRCRAFT UNDER 150 MPH
  15. i concur. i do not believe what cossey says about this chute.i do believe that councilman 24 is totally correct.
  16. interesting. if cossey is saying the canopy that was found is silk he would most likely be mistaken. parachutes have been made from nylon since WWII(the japanese cut off the silk supply).source for this information is poynter's parachute manual ,which for you non jumpers, is the parachute riggers bible.from personal experience(40+ years)i have not seen any canopy made after 1943 made of silk.and it is not fathomable that the military would have gone back to silk which is an inferior fabric for parachutes. maybe cossey is covering up something??
  17. i think riggers make good money....get respect..etc... ARENT DRUGS FUN???
  18. Ummmm... i 'm getting a little confused.beside the nb6 that cooper jumped with ,he alos took a chest pack(the dummy chute as it has been called)maybe it was already covered here but i am going to ask anyway, is it correct that cooper removed the dummy chute from its container and left it on the plane ,or am i missing something?
  19. "back in the day" rigging practices were not (how shall i say?)as precise as they are today.even tho the faa had a 22 lb pull force rule, rarely did anyone use a fishscale to check it.i myself was victim to what ya mite call neanderthal rigging( the reserve that i wore on my first jump could not be pulled even by 2 people on the ground.seems that when the rigger who assembled it installed the power ripcord handle for the sentinal auto opener, they did not make the ripcord pocket bigger to accommodate the bulk of the power r/c cylinder.anyway i had a partial mal on my first jump,BUT managed to clear it.lucky me.) but it would be interesting to find out just why this particular chute(s) was chosen .
  20. since there is a whole lot of cojecture on here,let me throw out this question... cossey supposedly says it was a 28ft canopy in the nb6 container. as a rigger w/ over 40 yrs experience in the field, i know that such a combination would have created a VERY hard pull(possibly even a no pull). since the nb6 most likely had a pull force of over 22 lbs(the faa limit)would cosey or whoever packed it be legally responsible for coopers death,if he bounced?(i.e. could they be sued by coopers estate for his death?
  21. the military did not use serial numbers on most of their harnesses /containers.they used to ,however stamp the serial number of the canopy onto the container(at least on army chest packs)i have never seen one on an nb6/8. as to the 26 ft/ 28 ft canopy...all i can say is that as a rigger and having packed lots of nb6/and nb8 s,if cossey had a 28 ft canopy stuffed into the smaller nb6 container,then at the very least cooper had a hard pull(or an impossible one).bet they find his body at the end of those buried lines.
  22. well for starters, the jump pilot at the dz (or any dz) would have been required to wear such a rig if the door was removed.(and just good commonsense to wear one given the nature of the activity involvedand the subsequent dangers to the aircraft)that is why there was such a rig on hand.
  23. you made a whuffo mistake. that is the serial number.the model number is NB6 or NB8.
