PLASTER CITY, California USA — This weekend saw the 8th annual Plaster Blaster hobby rocketry launch descend on the desert surrounding Plaster City, California, a small community located halfway between San Diego and Yuma, Arizona. Plaster Blaster is a nationally recognized and popular event sanctioned by both the National Association of Rocketry (NAR) and Tripoli Rocketry Association (TRA). The event has become synonymous with large rockets that test the limits of high power rocketry construction techniques, and this year was no different. Two years ago, spectators were treated to a huge 23 foot Star Wars X-Wing Fighter built by Tripoli San Diego and lead by Andy Woerner, the previous owner of Polecat Aerospace and What's Up Hobbies. The behemoth, sporting a wingspan of 19 feet and weighing over 500 pounds, crashed into the desert floor in a very spectacular manner when it self-destructed shortly off the pad. This year saw another enthusiastic project following the space-plane-inspired theme, a 1/3 scale X-15 project built by a group of individuals who label themselves the Punk Rocket Science build team. Coming off the successful launch of last year's Interceptor M project, the team, made up of members Todd Mullin, Larry Frelke, Jim DeVeau, Joe Conway, Jim McKinley and Scott Lawson, was ready to try it again. Built around an 18" concrete form tube, the X-15 would end up around 16.5 feet tall and around 200 pounds. Utilizing light-weight foam insulation for construction of the nose and other scale features, and then covered with fiberglass, the rocket, or plane if you will, created a striking profile. The use of foam allowed the team to keep scale features realistic, like the thick tail fin, without adding a lot of extra weight. Propulsion was provided by the way of two Cesaroni M2505's to handle the up part, while the down part was picked up by large surplus parachutes. Painted in the traditional black matte finish of the real bird, it's appearance was enhanced even more by the application of vinyl graphics provided by StickerShock23. The X-15 flew yesterday at Plaster Blaster, and the results would leave the team with a check mark in the loss column. Rising on the flame of the two CTI M motors, the rocket appeared to run out of steam at a point that didn't appear to be that high. At apogee, the recovery devices were deployed, only to see the main chute tangle and never deploy. The results were immediate, and while spectacular, they spelled the end of a great team project. |

Dudes, get a BDR guy on the team to discuss zig-zag fold of the chute for quick deploy at low altitude.
Sweet project. Congrats.
Just BDR Jerry
That's pretty accurate and positive to boot...
More facts...
Still not seeing anything that paints this X-15 as being "like the X-Wing" in any way except being a space plan and being an ambitious build and being a "treat".
Did I miss something?
I will say that the rocket seemed to lose steam pretty quickly and didn't have as much altitude as I would have liked to see - 200lbs is a lot of rocket for something as draggy as that - particularly with only two M's.

The list of things you have missed is long. . . . . (bless your virgin ears and eyes)
The X-wing shredded on boost and TRA's official head exploded.
The X-15 came in ballistic and hit hard enough to kill someone and TRA's head didn't explode.
Both complied with the offset distances in effect for state compliance at the time and there is some dispute if the X-15 met TRA details or not. Who cares. TRA rules and reactions vary.
Both flights had a type of failure one EXPECTS GOING IN and which safety protocols and construction methods are the actual safety protocol that keeps spectators safe.
One guy got screwed one guy did not.
Even if you somehow claim Andy Woerner did something wrong, which he did not, why didn't TRA leave him alone and kick out the RSO, the TRA members present at the launch and pretty much everybody BUT the guy assumed to have launch fever?
Because they are demonstratably stupid.

I have hosted launches where rockets with an expectation of failure were allowed to fly:
1. On the off chance it works and he learns something . . .
2. Because likelihood of success is not a safety code determinant.
One SHOULD presume failure and act accordingly. You seem to be telling me Andy did the right thing even though you disagree with him. Thank you.
Everyone there knew what was being flown and was advised to run away in fear. They refused and they loved it!!
Fly something radical. Get a "real" life.

Recommended test. Fly a J-L powered rocket of known good reliability and performance. Lay down 20 feet away from the rocket facing up. Launch the rocket. Change underwear. Report your experience here, if you can even find the words. Do as I do, not merely as I say.
Jerry, not sure if you saw the same video of the X-Wing that I did, but I clearly recall:
- Large crowd close to the rocket just prior to launch. All moved off camera prior to launch, but some question if they actually even had time to move to minimum safe distance.
- LCO and buddy moving short distance from rocket (I think I heard 40'?), then lying down behind a small mound of dirt.
- Rocket was launched with little expectation that it would hold together
- Questions around the motors installed, and whether it was even legal in California.
Bottom line, there was a bunch of things wrong with the X-Wing flight, regardless of any group affiliation.
The X-15's boost was less than spectacular, but the "disaster" came down (no pun intended) to recovery failure. From the video, I'm not sure extra altitude would have helped. But - that the video was taken from quite a distance away (unlike the X-Wing), and as best I could tell, there was no one anywhere near the pad or crash site.
Recovery problems happen. They're probably the #1 failure point in any flight. Crashing sucks. However, it's going to happen sooner or later, so you plan the range so when it happens, only the rocket & the ground are impacted (semi-unintentional pun).
