AeroPAC XPRS, September 23, 2006

ian.kluft.com / xprs2006 /
AeroPAC's XPRS (eXtreme Performance Rocket Ships) high-power rocketry launch event is actually a much longer event. I was there only Saturday because my truck wasn't out of the shop until late on Friday afternoon. Then I continued with a road trip on Sunday.

Here's the message I sent to the AeroPAC members...

I was only there on Saturday the 23rd. I had planned to be there on Friday as well. But some minor work on my truck turned into a major effort to fix things that the shop messed up. I got my truck out of the shop at 3:30PM Friday and was on the road fully packed an hour later, which was amazing but not good enough. There was no avoiding the Friday afternoon traffic jams out of the Bay Area and over the Sierras by that point. I took some serious detours via Hwy 84/Vallecitos Rd to Vasco/Discovery Bay/Hwy 4 to Hwy 99. (That's basically circumventing the parking lots, err... Interstates from the Bay Area to Sacramento.) I ended up arriving at AeroPAC around 2AM.

I thought I had to apologize for missing a Friday LCO (Launch Control Officer) shift that I had signed up for online. I had tried asking on the list to get the message to them that my truck wasn't out of the shop on time. But Richard had printed the schedule before I was back on the schedule. So they had found others for the Friday afternoon LCO shift they didn't know I had signed up for. :-) I still found the night launch LCO shift open and wrote my name in for that, which was one of the shifts I wanted to do.

The launch during the day was worth the short visit. Lots of meeting people and their fascinating projects. I got pictures of the Nibbles vs Mercury Joe drag race, which at first Nibbles seemed to have won off the pad but only Joe ended up surviving. The largest project launched that afternoon was the 3-stage N-N-M attempting 96K - the 3rd stage didn't light but all the stages were recovered intact. With more projects like that attempting the 100,000' neighborhood, that record is going to be reached by HPR some time soon.

The potluck as usual was a lot of fun. Thanks to everyone.

The night launch was a lot of fun. It was only my second time LCO'ing a night launch. As Sue mentioned (thanks for the really nice message Sue) the children brought up a lot of models during the night launch. Though there was some high power too. I had a lot of fun.

I remember one moment of ad-libbed comedy when Conner's rocket came back on chute obviously toward the LCO table. I stepped to the side out of its way and said over the PA system, "It's going to hit the LCO table in 5, 4, 3, 2, 1... and it's down but it hit the guy line for the FM transmitter. Is 99.9 FM still on the air?" ... "OK, I heard a honk from the east end. Thanks. We're still on the air." When was the last time we got to do a 5-count for a rocket landing on the LCO table? :-)

The kids were well-behaved. Though there was a moment of serious adult supervision needed. One of the children didn't have a flashlight. So one of the 14-or-15-year-olds said, "It's OK. I've got my lighter." I immediately asked, "What kind of 'lighter' do you mean?" He showed a Bic lighter as expected. I said what any of you would have, "No fire near the rockets. Get a flashlight." The common sense of that must have clicked with them because they promptly went to get flashlights and were back a moment later. Those of you who have kids - this is something you should make sure they know.

The rockets kept coming until 10PM. It isn't as late as we went at Aeronaut (when we went to the 11PM end of the waiver.) But then again, the weather and temperature were perfect at Aeronaut. It was seasonably cool at that time of night at XPRS so it was actually really good that we kept going as late as 10PM.

I had taken a short nap during the afternoon because I knew I wasn't going to get a lot of sleep that night. In order to reach my road trip goal for Sunday, I woke up early and, quietly as I could, packed up my camp and was on my way at 4:30AM. Only at the very end of the packing did I hear a voice from a neighboring camp. Sorry about any disturbance.

Why did I go on a road trip? I needed to take my mind off not being able to attend another launch on Monday that I had been planning for a year. I was going to go to the inugural space launch at the New Mexico Spaceport, a rocket by my friends at UP Aerospace. But an unfortunate situation out of my control left me unable to participate in the launch.

It was so disappointing that I continued to take the time off from work and planned to do something else. I went to southwestern Utah and hiked around in the mountains looking for space shuttle debris for a couple days, capped by a couple visits to national parks in the area. The search for "Debris 6" from the space shuttle is a project that Stratofox dusts off once in a while when someone gets a chance.

img_6635.jpg - 2006:09:23 10:42:08This group has a nice collection of rockets.


img_6636.jpg - 2006:09:23 10:45:03Steve Pope allowed a sneak preview of the cover for this year's AeroPAC holiday party DVD cover. As if there wasn't enough anticipation already...


img_6637.jpg - 2006:09:23 10:55:12Jim and Becky prep a rocket for flight. (Just kidding. Jim is trying to salvage what he can from a crashed fuselage.)


img_6638.jpg - 2006:09:23 10:59:42The To100K booster is sitting ready to test the new O motor during Monday's experimental launch.


img_6639.jpg - 2006:09:23 11:44:57Noel is ready (if he can get permission) to attempt an airstart with a model rocket motor on a model airplane. So in effect the model planeis the first stage.


img_6640.jpg - 2006:09:23 11:55:57A large rocket lifts off from the away pads. If anyone knows whose this is, let me know.


img_6641.jpg - 2006:09:23 11:56:01The rocket fromt he previous photo climbs out nice and straight.


img_6642.jpg - 2006:09:23 11:59:10Two parachutes are the parts of one rocket, intended to be recovered this way.


img_6643.jpg - 2006:09:23 12:00:43Two parachutes from one rocket drift down at different rates. It's getting harder to keep them in the same photo.


img_6644.jpg - 2006:09:23 12:02:19Touchdown of the first section fromt he large rocket in the previous photos.


img_6645.jpg - 2006:09:23 12:02:55The parachute settles down from the touchdown in the previous photo.


img_6646.jpg - 2006:09:23 12:03:50The second part of the large rocket in the previous photos touches down.


img_6647.jpg - 2006:09:23 12:14:44John Ballard (a Stratofox invitee) shows the rocket that he found 6 miles away.Usually the advice is to get the GPS coordinates and bring that back,in case the owner is out looking for it too.But this was in a place where it risked getting run over by playa trafficunrelated to AeroPAC.So John made the call to make sure the owner gets it back in one piece.


img_6648.jpg - 2006:09:23 12:33:23This group is setting up a three-stage N-N-M rocket which was sim'ed out to a potential altitude of 96,000'. (When it did fly later, I didn't get a picture of the launch. The 3rd stage didn't light. But all three stages were recovered.They were using Greg Clark's BigRedBee transmitters.)

img_6650.jpg - 2006:09:23 13:00:11This was supposed to be a drag race between Nibbles the Cat and Mercury Joe. Nibbles is launching. Joe is still on its pad.


img_6651.jpg - 2006:09:23 13:00:14Nibbles the Cat flies alone in what was supposed to be a drag race with Mercury Joe.


img_6652.jpg - 2006:09:23 13:00:16Mercury Joe finally gets around to flying, with no chance of winning the drag race.


img_6653.jpg - 2006:09:23 13:00:19The trails from Nibbles the Cat and Mercury Joe during their drag race.


img_6654.jpg - 2006:09:23 13:00:22Nibbles the Cat fires is second stage.


img_6655.jpg - 2006:09:23 13:01:48Mercury Joe's booster is under parachute. (In this aspect, Mercury Joe wins the drag race. Nibbles impactedwithout deploying its chute. There was a large crowd at the crash site.)


img_6656.jpg - 2006:09:23 13:03:29Another large rocket launches from Away Pad F.


img_6657.jpg - 2006:09:23 13:05:53Jamie and others race toward the Mercury Joe booster as it drifts toward landing.


img_6658.jpg - 2006:09:23 13:06:12Touchdown of the Mercury Joe booster.


img_6659.jpg - 2006:09:23 13:07:15The crowd around the crash site of Nibbles the Cat. (Nibbles is a stuffed animal, just to settle anyone's nerves about this.)

img_6661.jpg - 2006:09:23 13:07:56The crowd thins as the pieces are picked up at the crash site of Nibbles the Cat.


img_6662.jpg - 2006:09:23 13:08:04Jamie recovers the booster from Mercury Joe.


img_6663.jpg - 2006:09:23 14:00:47People set up rockets on Pads 21-30 in the foreground. The desert mirage is clearly visible in the background.


img_6664.jpg - 2006:09:23 14:02:27Steve Pope is everywhere getting video for the holiday party DVD.


img_6665.jpg - 2006:09:23 14:35:37It's never a good sign when a rocket lifts off the rail at this angle. This looks like too much deflection to be from wind so itprobably has asymmetric thrust.


img_6666.jpg - 2006:09:23 14:35:39Mike Dennis' rocket deployed its parachute during its boost and shredded into a cloud of debris. This is about the time that the Launch Control Officer hits the big red button to sound the heads-up siren.
