Right now this skydiving section is divided into three parts:


Jump Stories

Basics - Learning - Teaching

Rainbow Line


We skydive in order to feel feelings and connect with ourselves and others and life.
Freedom is not a body position. It is not a maneuver either.
Maneuvers and body positions are just something to do while we skydive together.
They are just one way to produce feelings.

"They don't come out to watch us die. They come out to see us live."
"Skydiving is the doorway. We are the experience."

In June, 2002 Parachutist did a profile on me. Author Brian Giboney had to fit it all on one page so he had to select just a few words. Here's the uncut version:

2002 - The jumpstart
2002 - The profile

"Why?" is the plaintive cry of the whuffo:     "Whuffo you jump outa them airplanes?"

And we can't tell them. If we were in their framework, we wouldn't be doing it either, and if they were in ours, they wouldn't be asking. But we *can* express it to each other.

Man small.
Why fall?
Skies call.
That's all.      Andy Keech

1995 - Bonnie Dutile
19?? - Charles Lindbergh

The other side of this, the far end, is the feeling of fading away.

1974 - Andy Keech - Skies Call

Skydiving has become mainstream.
We are teaching people to scuba dive before they learn how to swim.

Jump Stories

"All jump stories are true, even if they didn't happen that way."
"Who are we to let the facts get in the way of a good jump story?"

Some 60's and 70's stuff.

Post AFF A License Coaching

In 2001 we started adapting the ISP version of the A license to our student program at Calhan. We didn't change the AFF phase much, but we did change the coaching phase to reflect the viewpoint that:

  1. People come out to skydive, to experience freefall, flying, growing, learning, making new friends and so on. They don't come out to satisfy a bunch of dry license requirements.
  2. Canopy control and exit separation and such need much more emphasis first before the freefall requirements.
  3. People want a short break (freefall recess) after the rigors of AFF.

When they graduate from AFF they get a student packet which has:

2002 - The Student Handout - A One Page Executive Summary
2002 - The Diagram
2002 - The Coach's Handout
1999 - Some Fundamental Skills Common to all Jumps
2002 - A Summary of Exit Separation

2002 - Wings Level

1995 - What's after this Coaching Phase (Who Ya Gonna Be?)

Two Page Proficiency Card
A Flight Planner (aerial photo to draw on)
A Packing Video
A Pullup Cord

2004 - The prop has turned and Calhan has joined the big dropzone in the sky, but I still do a version of this at Mile-Hi in Longmont, Colorado.

Upper Winds and Exit Separation

John Kallend's Freefall Simulation Program
His notes on this program

In the early 90s there was a legendary debate on rec.skydiving about exit separation and air speed vs ground speed. We had people hauling the dropzone around with a giant tractor, jumping out of tethered balloons in 100 mph winds, equations, ascii diagrams, strong emotions, and clever, misleading arguments in all directions. I'm sure none of us would have imagined that 10+ years later, 2004, the debate would still be raging on.

Exit order, slow fallers then fast fallers then high pullers for into the uppers jumpruns, is mostly accepted now, but separation between groups is still unresolved and frequently debated.

In going back and rereading some of these old threads I found one post that really captured my feelings at times.

Cindy Pirkkala:
" ... I thought I had it figured out, but I've gone back & forth so many times on this thread that now I'm not sure what to think. In fact I'm totally convincedd out, but after reading this thread, my own thought processes have become so confused that the only thing I know for sure is that I have absolutely no idea what in the hell I think, so I'm going to just stop jumping. (Not a chance)"

Here's a few threads from that time. There are many more.

"Don't hose the last groups out" translates to "Just kill the people in the first ones instead".
