    . . .Gas statio in St. Lois. Well according to Hillary Clinton he does.

    Couldn't find it on the web, but the sound bite was just played on the Hannity Radio show.

    Probably cant quote it perfectly, but in a fund raiser she says, . . ." I love this quote, I got this quote from Mahatma Ghandi. He owns a gas station in south St. louis, evidently there is a lot of wisdom coming out of that gas station. . ."

    What a racist!



    The spelling of Gandhi is Gandhi


  3. Just incase someone was looking to buy one. These watches are built for sking, mountain/rock climbing and golf.

    The following is from the sunpath homepage, link below.

    Stylish Suunto wrist watches that features a range of functionality, including an Altimeter that is ideal for Skydiving.



    Go to the Sunpath

    The following is from the SUUNTO USA website. Scroll down to the General FAQ section.

    Is the Suunto Wristop Computer going to replace a true baseplate compass, or other precision instrument?

    No, the Suunto Wristop Computers are NOT intended to be used as a substitute for professional or industrial precision instruments and should NEVER be used to acquire measurements when skydiving, hang gliding, paragliding, gyrocopter riding and flying small aircraft.

    A custom ordered Jav is made exactly for the jumper also. I'm not sure what information you are going on there...



    Maybe I'm mistaking on this, but regardless, I sure as hell won't wait over 5 months for a rig -



    If you thought a 5 month wait was too long you should'nt have ordered it in the first place.

    The dude asking the question should have thought about it before placing the order. Yeah yeah I know the whole instant gratification thing, but I learnt (in part due to injury) that its better to wait for what you want, especially when it comes to skydiving gear.

    Also seems like the winter months have made the jumper quite jumpy ;)

    Raven is one of the two most popular reserves. Loads of documented saves. Even if Precision did make a mistake, it's obvious $50M is a bit much. It's probably more than they've made in total on all canopy sales ever!



    Agreed $50M is way way too much.

    I can see a jury that sees one side present a case and another side not even care to present a defense, wanting to award putative damages generously.

    This _may_ not be the fist case of a reserve from this mfg faling.



    Don't they also sell the Escape Chute??

    Read this article Gear Article

    The following is a quote from that article.

    According to Cliff Schmucker, president of the Parachute Industry Association, “there’s obviously people out here trying to make a quick buck in a bad situation….At least one person was looking into congressional relief for the liability issue.”. This would be disastrous, as it would remove accountability for improperly designed, tested and marketed products.




  12. Let us go into the world of variables.

    Canopy starting height = h ft
    Forward speed of canopy = c ft/s
    Descent rate of canopy = d ft/s
    wind speed = w ft/s

    the area of the ellipse in which the canopy can land is

    Pi * [(h/d) * c] * {[ (c + w) * (h/d) plus or minus (c - w)* (h/d)]/2}
    that is

    Pi* (h/d) * c*c is the same as no wind conditions when the canopy speed exceeds the wind speed. Always!!

    i.e The wind has no effect on the area in which the canopy can land even though the shape of the area is now an ellipse!!

    The previous calculation was messed up because of the rounding. :$ I recalculated without rounding and the result is the same.

    if the wind speed exceeds the canopy speed

    The formula becomes

    Pi * (h/d) * c * w

    and yes this ellipse is bigger in area than the circle.

    It is obvious afterall!! :)

    This one got me thinking.

    Given:

    Canopy open at 2,000 FT AGL
    Canopy forward airspeed of 25 mph
    Canopy rate of descent of 750 FPM

    Area that can be reached in 0 and 20-mph winds

    0 mph wind:

    Under canopy for 160 seconds at 36.67 FPS airspeed
    5867.20 ft (1.11 miles) in any direction (radius)
    3.87 miles^2 the canopy can reach in 0 mph wind

    20-mph winds:

    Under canopy for 160 seconds at 36.67 airspeed and from 7.33 FPS to 66 FPS ground speed
    1172.8 ft upwind [holding]
    10,560.00 ft downwind [running]
    7,509.51 ft crosswind [crosswind] (5862.20ft 9-degrees to the wind line and drift downwind 4693.33ft)

    If someone would figure the area for 20-mph winds, that would be great. Obviously, 20-mph wind scenario results in a much greater surface area that the canopy can reach.

    When we tip the cone the circle becomes an ellipse.

    The area of an ellipse is http://thesaurus.maths.org/dictionary/map/word/2942.

    The area is actually slightly less ....

    From the above calculations by Derek,

    a = 10560 + 1172.8/2 (running distance + holding distance(this is in the canopy's direction when faced into the wind, this number would have to be subtracted when the canopy goes back in the wind or the speed of the canopy is less than the wind speed)/2 = 5866.4

    b = distance flown when crabbing 90 degrees to windline. This is same as the radius of the circle in the previous case of no wind. 5867.2

    Now this makes the area of the ellipse after converting to Sq. miles

    Area = 3.14 * (5867.2 * 5866.4 ) divided by 5280 * 5280 = 3.88Sq. Miles.

    I am saying that this is less because the area of the circle is 3.14 * 5867.2 * 5867.2 before conversion to sq. miles.

    Interesting !!!!

    I gave it more thought because it seems impossible. The tip the cone anology makes it seem that the long radius of the ellipse would lengthen when the cone was tipped. However on further thought, it seems like this is a little more complex than making a blanket statement that covers all cases. 750 FPM downward speed might not be realistic for a canopy that only has a forward speed of 25 mph. A change in that to reflect a more floaty canopy would show a considerably different result.

    Mine has 1.21 and the clock does not work. It keeps track of the date fine, but it does not display the correct time (an odd problem, since I would think that it would mess up the date if it did not know what time it was).



    I have not played around with the Neptune since my injury but I believe that the time can be set. Also Go to Alti-2 website, they mention a bug in the year part of their code.

    And a suggested corrective measure until 2.0 is released.


  15. They say the 2.0 software will allow downloads of the log data. Paralog is claiming that their software will work with the Neptune before alti-2 is ready to launch 2.0.

    This is a good thing for us Neptune Owners. How much does the Paralog Software cost?

    I think its a good thing that Aerodyne set a precedent by including all the popular options in the base price instead of charging an arm and a leg for options.



    Actually, the Voodoo from Rigging Innovations has always included everything standard.



    One thing that nees to be said is that SS is an option on the Voodoo.

    Hi Everyone. I need some help here...I have a new Sabre2 150 (loaded @ 1.3) and am getting snivels in the 1600- 1800 foot range. It also does the left/right "turn and seek" that have been mentioned here on numerous occasions, but it's the VERY slow inflation that has me puzzled.

    I do not fold, or stuff the nose and use the 525 micro line held with tube-sto's along with a ZP bag and 27" KL pilot.

    Any suggestions would be appreciated.



    Do you have a neptune? Or any other electronic device that tells you canopy deployment altitude?

    My Neptune said I was under canopy at 3800' when I waved off at 5700 and pulled. And no I did'nt feel anything like a snivel on opening. I think I was open before 4000'. I jumped the original sabre not the sabre2.

    Driving is less dangerous but it says diving on the poll so I voted for that ;)



    You know I realized that but there is no way of fixing that after you start a poll.

    Also I think there are many minor incidents in skydivng as well like all the non fatal accidents on teh road.


  24. Edited : The option 1 should say Driving

    My whuffo friends tell me to be careful skydiving.
    I tell them I should be careful driving to the DZ I'm more likely to get killed doing that.



    Not really 40000 might be a big number compared to 23 but the number of drivers in the US is much much bigger number compared to the number of skydivers in the US.

    Say a skydiver makes 2 jumps a day on average(I think it might be less), a driver on average makes atleast 2 trips. I am sure the number of trips made in a year in the US is well into the billions.

    On a percentage of jumps to fatalities vs auto deaths to auto trips, driving is safer.
