    http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=4155226;search_string=sigma;#4155226 That, plus the RSL safety pin with lots of velcro... In the accident above, it was removed (unauthorized operation), and Sigma still had issues...
  2. skydiverek
    What rig is that?
  3. skydiverek
    No, please see the above post. Also, I think the Sigma rig is patented in at least USA and EU.
  4. skydiverek
    In what way? The 3-ring patent expired approximately 13 years ago (20 years after its invention). I believe, Bill Booth had been charging other manufacturers 6 dollars for every rig using the 3-ring release system (1 dollar for every ring). I am talking about solo rigs, not sure about the tandem drouge release 3-rings.
  5. skydiverek
    That too. But my description is still valid.

    1 MB would be cool and still cheap, I quess.

    OK, so I understand that SIGMA container is superior to other tandem containers in a way that if the main container opens, the drogue is automatically released, preventing the out-of-sequence deployment. That has been the feature marketed quite heavily over the years and it makes a lot of sense (especially, when you examine the 'tandem fatality list' prior to Sigma introduction...). The question is: who experienced this feature 'in action', meaning container opening and autiomatical drouge release. I would like to hear some first hand accounts of some thankful users :-). And the second question: did anyone experience out-of-sequence deployment on Sigma? (I cannot see that happening, but still...).

    Also, Vector3 reserve PC is 45 lbs strong. Javelin's is 22 lbs.
  9. skydiverek
    Number of flaps (to be pushed by reserve PC) has nothing to do with that phenomenon. Rather groomets (creating friction on the loop). Riggers: how many grommets does the cut loop 'tail' have to clear on a) Javelin b) Vector ?
  10. skydiverek
    Yup, I have heard only about two such entanglements, both on Javelins. One fatal...
  11. skydiverek
    I was not talking about the badly seated grommet. Rather, abot the 'detachable' - a material 'tounge' sticking out from the wall (between main and a reserve container). Like on Javelin. Closing loop originates from that 'tounge'. A line can halfhitch around that tounge (this is what happened in the first movie I linked). I do not understand why the main closing loop originates from the 'tounge', and not directly from the wall. Exactly. So the cut 'tail' on Javelin is even longer than on Vector!

    It also promotes entanglements with the suspention lines, such as this one: http://www.youtube.com/watch?v=45VtzmtA_C0 Such a placement leaves the longest 'tail' of the cut loop, ending up with this (added poor rigging and no silicone on the loop): http://www.youtube.com/watch?v=HYIUjKGxagI http://www.dropzone.com/cgi-bin/forum/gforum.cgi?do=post_view_flat;post=2101957;page=1;mh=-1;;sb=post_latest_reply;so=ASC

    So the Orlando tunnel is sucker? Or blower? I guess sucker, and the fan fell from the 'ceiling', right?

    1 ride, no cutaway.
  15. skydiverek
    So, the serial number list is actually shared by military and civilian gear? For example (fake list created by me): 50000: civilian V3 50001: civilian Sigma 50002: military Sigma 50003: military Vector 50004: civilian V3 Is it the way it is?
  16. skydiverek
    Billy Weber has over 500 cutaways (intentional)...
  17. skydiverek
    Correct.
  18. skydiverek
    You are very correct. This is LOGICal...

    Cypres fires at approx 1100 feet in head-down.
  20. skydiverek
    You would appreciate being alive in the first place. If you watch YouTube videos of Cypres fires, people are spending 15 seconds under open reserve. 15 seconds x 16 ft/second (descent rate) = 240 ft AGL opening altitude.

    N/A
  22. skydiverek
    Yes.

    Answer is here, 15 000 jumps: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=1499051#1499051
  24. skydiverek
    True. World champion Rob Harris was killed jumping a 3-canopy rig...
  25. skydiverek
    Why? A non-US citizen may bring a non-TSO'd gear to USA, and jump it there. BUT, Basik Seven does have the TSO, from what I recall. So, this is not even a concern for the US citizens jumping in the US.
