    http://en.wikipedia.org/wiki/Larry_Walters I think this is the original flight.

    Approximate dimensions for rectangular and triangular LZ's. Dimensions are feet.

    The entire sequence is masterfully thought out.

    Odds are you’re going to jump once. Buy the vid. Buy the air. Remember, it’s a risky sport.

    Possible dates? Possible locations?

    I thought you said body position lines twists not canopy performance.

    Was it your pack or the youngster’s?

    I also have a very specific routine before getting in the plane. My DZ has learned I won’t skip through it and they don’t mind. They just put me on the load that fits that time table. I gear check everything, check the winds, check the landing pattern, stretch, dirt dive a couple of exits and pulls then I’m ready. Takes about 20 minutes minimum. What you failed to realize is you were in a negotiation. A negotiation for the process. In any negotiation you need to be able to say no when your bottom line is surpassed. Your next step in the negotiation is to say “I need 10.” If they yell, sit down.

    Simple physics Speed at time of deployment (after main is out of the bag) = Vo = 110 mph = 160 ft/s Speed after deployment = Vf = 10 mph = 15 ft/s Y = distance traveled = 0.5*a*t^2 +Vo*t+C t^2 = t squared C is a constant that is zero in this case (trust me) a = acceleration to stop from Vo to Vf t = time interval from Vo to Vf (read snivel time) Take the first derivative of y=0.5at^2+Vo*t+C dy/dt = a*t+Vo dy/dt = speed after the reaction = Vf Vf = a*t+Vo Both Vo and Vf act downward and “a” acts upward against the speed (that’s why you stop falling) -15*ft/s = a*t-160*ft/s 145*ft/s = a*t a = rate of acceleration during inflation = (145/t)*ft/s/s g = normal gravity = 32.2*ft/s/s G’s pulled = 1+a/g Table of Values t (secs) a (ft/s/s) G’s 1 145 5.5 5 29 1.9 8 18.125 1.56 10 14.5 1.45 At that’s why a line dump smacks you. (fixed the table)

    There you are with the legal angle again. Do you jump with a Gopro?

    Bravo!

    Found this thread with some more great information. And Airtwardo’s red/white PZ-81. http://www.dropzone.com/forum/Skydiving_C1/Skydiving_History_%26_Trivia_F21/PZ-81_Parawing_P3254543 Based on PCChapman’s and Calvin19’s comments and the Mi-8 jumpship this is probably a recent eastern European video. So the PZ-81 is still in use, true?

    The physics is spot on. If you remember the X prize competition (first civilian group to send a vehicle into orbit twice) Dick Rutan sent a plane just into space and bounced along the edge of the atmosphere surface until the vehicle speed reduced enough to fall back into the atmosphere. He used the basic theory of low speed = low heat on reentry. http://scaled.com/projects/tierone/spaceshipone_flies_again_within_14_days_-_wins_10m_x_prize

    Take the chem job at $35k. I doubt you’ll be booking much overtime your first year so you will have free time. Use the $35k to buy weekend jump tickets. Apply for grad school next year and you will have bolstered your resume and been able to jump.

    Do you actually jump? Or fly? You seem to post on a flying website also. Or is it strictly theory?
