    Cypres maintenance turnaround time

    Did it last year, 4 weeks.

    Shippng AAD with USPS

    I used the automated postage machine at the P.O. to ship mine. Got there in 3 days with delivery confirmation. They shipped it back the same way. Why speak to a clerk at all?

    BOD Meeting July 2018

    The complacency sounds a lot like what happened at Skydive Sussex but that would really be a sore point with the Board in both how it was handled and how some GM DZO's get a little bit more privilege.

    a question about old cutaway systems

    Had my first rig, an old Wonderhog, changed to R-3's from shot and a halfs. Had 2 cutaways with them but the second was a near miss collision where the main collapsed. A line or 2 wrapped around the R-3 and I had to dig a little to get it. Bought a new container with 3 rings.

    Gear Check!

    I have always tried to impart to my students that knowing how the specific equipment you are jumping works is vital. I have had people try to drag me back in the plane, refuse to pack the reserve, and be totally befuddled trying to pack for me. That was because at the time I was jumping an SOS system with a bungee pilot chute! There was no cutaway handle, I was told by a new rigger the cutaway cables were too long and that they needed to be changed out (even after demonstrating why they were that long), and watching a packer try to cock a bungee was hysterical! It's as important for a jumper to know how his specific gear works and then it's easier to know what to check. In this day and age gear is becoming more standardized but there are still quirks to individual rigs.

    Bungee pilot chute

    Good luck trying to find one. After 2000 jumps on mine with zero problems, the lower mesh finally tore and I decided to replace it. I tried six gear dealers and even posted on here trying to find one with no luck. Let me know if you find one.

    Your First Reserve Ride - Go Time

    Not too bad but a lot of drop zones (including some very large ones) don’t teach the cutaway method you mention so it might be a bit too specific. A lot of drop zones use a 2-hands on each handle cutaway sequence for a number of reasons. This type of cutaway utilizes the sequence of “Arch, Look red (identify cutaway handle), grab red, look silver (identify reserve ripcord), pull red, grab silver, pull silver”. The cutaway handle is thrown away prior to pulling the reserve ripcord. This sequence has a number of advantages over the one-hand on each handle technique. It allows the jumper more pull force for a hard cutaway and also allows the second hand to sweep the cables clear of the housings to ensure both risers release. It also frees your hands in the event that the canopy is not completely released. Think about clearing a stuck riser cover or a line entanglement after you have cutaway and you have already started to pull the reserve ripcord. You need to ensure you have completely released the canopy before pulling the reserve. With a one-hand on each handle sequence muscle memory will sometimes cause a reserve pull. Also, as seen by a number of Instructors over the years, in the stress of a cutaway, a number of students have managed to pull the handles in the wrong order. A 2-hand cutaway makes this much more unlikely and if a MARD or RSL is used the reserve is usually open as fast as a manual pull. Lastly, no matter which sequence you currently use don’t change it unless there is a very specific reason for doing so. You will lose the long term muscle memory you have worked so hard to get and could cause confusion in a high stress situation. Jumpers discovered back when we transitioned from regular use of modified military equipment to modern sport gear that muscle memory could sometimes cause problems if the jumper was not specifically trained in the techniques the different equipment required. Be careful out there gang! A cutaway should not just be a mindless pull of 2 handles. It should be a combination of thought with the urgency of trained muscle memory.

    Looking for WFFC Video

    I think Tom Sanders was the editor/producer. He posts here once in a while. I'd ask him if he still has any?
  11. Another one? I still have a copy of the results of the first one I did back in 1983. What would be an interesting project would be to collate the results of the last 50 to 100 mental health surveys done of skydivers rather than starting new ones. Or maybe using the results to show trends over the last 20-30 years.

    4 Ways to Avoid Pilot-Chute-In-Tow Malfunctions

    Some of us older jumpers still use bungee pilot chutes which would eliminate 2 of 4 problems mentioned that can cause a PC in tow. They are non-packing sensitive and when the bungee wears out or breaks the PC just becomes a non-collapsible PC and still will operate just fine. Some times newer is not necessarily better.

    10 Things To Note Regarding Malfunctions

    An excellent article! The only thing I would change is the "hold on to the handles" advice. A lot DZ's teach a 2 hands on the cutaway type procedure and unless there is a very specific reason to change, the muscle memory of practice cutaways is more important than trying to save a relatively cheap cutaway handle. We found out in the "old days" that even changing something as simple as a main deployment handle location required extensive retraining.

    Wrist vs Chest - Altitude shown

    I wear a wrist, chest, and audible. The wrist, I can see while on grips, the chest, others in the formation can see, and the audible tells me when my student should pull, I should pull for him, and when I should give up trying and save myself. They all usually read within 2-300 feet of each other.
  15. I've jumped with a couple of people you might consider famous, but the best was jumping with Art Thompson. He was the technical director for the Sage Cheshire team that created the high altitude system for Felix Baumgartners jump. He did a tandem with me and gave me a challenge coin from the project in appreciation!
