  1. How close are you to Chambersburg? That was a GREAT DZ last time I visited it. If you have not been there yet give it a try, if it is within reason.

    Of course I drive 4 and 1/4 hours to the DZ I mostly jump at.

    I have never been the Skydive PA. So no Opinions there.

  2. I have stalled a Storm with out wraps as well.
    Why? Just to see how it would behave so I would know, I do not anticipate needing to use the info for any thing else.

    Scott - I agree with the points of the stall being performed up high! I also follow your thoughts about the "why do it?" and understand the lack of it being needed or even capable with lots of the newer designs.

    I still think knowing how any canopy will behave is good knowledge, and knowledge is power! (Good old School House Rock!)

    I am one of those "Education" guys.

  3. True, but it it good info to have. Knowing when a canopy will stall and how it behaves in the stall, and in it's recovery, is good info for later use.

  4. "It doesn't explain why or how the airborne began doing that in the first place. Oddly, only MPs and airborne were permitted to do the 'pants leg' tuck thing into their boots."


    The blousing came about because of the Leggings. Leggings where used to keep bugs and dirt out of the lower legs during excercises and combat operations, but not worn in Garrison. The original Boots used by the Infantry where lower and provided little to no ankle support, so not ideal for Paratroopers. Tankers had just gotten a new boot that was taller but had buckles across the arch, not good for jumping. The Tanker Boot was modified for Airborne Troops and the Cocharan Jump Boot was developed.

    Since the jump boot was providing the ankle support and bug protection, with the pants bloused into the top of the boots to keep the dirt and bugs out, leggings where dropped by the Paratroopers . This also allowed them to show of the new Paratrooper Boots that only they had authorization (although officially it was not authorized till later) to wear.

    And today they still blouse the pant legs in to Jump Boots.

  5. Yes, the lines are out there for Skydiving Canopies as well. Flight Concepts Inc puts black, red and white on various Demo Team canopies and I am sure could do it for other canopies they make as well.

  6. Oh yeah,

    Well I go get 180 freaken roses, cost me $540, head on over. Where talking things are looking good, then she asks if I have the "roses". I say "be right back, three trips from the car later and then she doesn't even want the damn things! Why even ask for 'em then? Sheesh:)

  7. Rough Terrain Suits are used by some Smoke Jumpers, and some Paratroopers in the US (and I am sure of other places).

    I have two Rough Terrain Jumps, one in the suit:S.

  8. Then you would use D=KAV, in two parts.

    For Freefall D=3 (the constant or "K")xAltitude (thousands of feet falling reduced- 9K=9)x Velacity (averages of the winds for each thousand foot increment).

    or
    D=3x9x12 D=324 m This is freefall drift.

    For the round Canopy flight

    D=25x3 (openning at 3K) x Velocity (average again)

    or

    D=25x3x10

    D=750

    Or the spot will be 1074 m from the center of the peas. (based on the tube scenario, not swagging any thing like forward throw or climb out etc. and using a perfect one direction wind chart)

  9. Probably more to do with what General Yarborough was wearing when he met the President.

    Hint: Look at some of the photo's of the eternal flame at the Presidents grave. OF course it will have to be a photo taken the first day or two after the buriel.

    Edited 'cause I goy my names backward. Must early on set of that thing that messes up your memory, oh hell, I forget what its called.

  10. Flight Concepts does complete rigs (Wings Conatainer) or Canopy Deals. Works out to around 45% off for a complete rig and 40% for a main/reserve combo.

  11. This is already done to an extent by MFF Jumpmasters and AF Navigators using a modified version of D=KAV.

    D=Distance, in meters
    K=Constant
    A=Altitude, in feet, reduced to one digit (i.e. 8000=8)
    V=Velocity, in knots

    They use the formula twice, once for freefall drift (canopy opening altitude up to exit) and the second for canopy drift (openning altitude to ground).

    They also break the direction down for Freefall and Canopy drift as well. They average the direction and come up with a mathematically correct spot once the two portions are plotted out.

    It is a good start for the wind dummies, but load one (or the WDI's) will show that load 2 should mnake some minor corrections. For the SOF guys if it is the only load, well good luck.
