Location: Redondo Beach, CA. USA

Certification Level: L2 NAR

Club Memberships: NAR, SCRA, ROC, MDARS

Favorite Rockets: The Launch Pad Osiris


I was a child of the 1960's and the dawning of the space-age. Aerospace and Astronomy were my passions then and still are to this day. Back then Model Rocketry was cool. Even science was cool. In the mid-70's I joined the Air Force and my rocketry went dormant for a while.

Fast forward to 1996. I moved to southern California (from Rochester NY) and I became a B.A.R. I was very active in ROC (NAR #538) from 1998 to 2002. In 2003/4 things changed professionally and again my rocketry went into storage. In 2010 things changed again, and rocketry came out of storage. So maybe I am a Born Again and Again Rocketeer. :)

I live in Southern CA with my wife and 6 wonderful kitties. I am a software architect specializing in Java and open source based web scale architectures.

Other activities I enjoy are building and flying wooden R/C Gliders (you know old school kits), R/C Helicopter... try to learn on the simulator, Astronomy, live theater, fine dining, cocktails, and wine tasting. I am an Atheist. Strangely I am not an amoral axe murderer, though apparently in religious circles I am considered so.

I enjoy all aspects of Rockets. 1/8A through M. I have just as much fun launching a MicroMaxx Rocket as a K impulse rocket.

Model Rocket Building: Peter Alway Saturn IV Build, Part 1, Plans and Parts
This model was from Peter Alway's Home Page. I can't seem to find it now! If anybody has a link, let me know. The website had plenty of sport and scale plans including a Vostok, Saturn I and a Flying Rabbit that looks better than the old Estes Cloud Hopper. You can get Peter Alway's books: Rockets of the World HERE and Scale Bash HERE Both highly recommended! There's one model that has been on my "to-do" list for a while. The SATURN IV! This is Peter's "psuedo-scale" design of a Saturn that could have existed between the Saturn 1 and Saturn V, the Saturn IV. Full resolution plans aren't ...

Model Rocket Building: Estes Payloader II #3022 Build, Part 1 Parts
All the parts are standard and of good quality. For a while it was rare to find kits with clear payload section tubes. I'm glad to see they made a comeback. Part of interest: The laser cut fins didn't get cut all the way through the wood. While you should never just punch fins off the sheet, these will take a few passes with a sharp knife to free them.
