D day

I moved to Estes Park CO this past August, but this isn’t the first time that I have been acquainted with the word Estes. Back in the late 60’s, man was reaching toward the stars and every kid had the dream within themselves to do the same. It was the perfect time for the model rocket company Estes to flourish. Estes model rockets were originally produced in Denver CO before moving to Penrose CO in 1961. Our local hobby shop sold Estes model rockets. These weren’t just rockets that you built out of plastic and displayed on a shelf; these were balsa wood, plastic and cardboard core rockets that you loaded with a real gunpowder rocket engine and launched from a remote launch system. The exhilaration of taking the time to build a beautiful bird then take it to the nearest open field and start the countdown to launch. Upon ignition, the engine ignited rushing your rocket to 1,000’s of feet into the air, reaching apogee then releasing the parachute to glide to a soft landing. This was the era of Alan Shepard, Neil Armstrong, Gus Grissom and the other 4 of the Mercury 7 team. Living in Nansemond County left a boy a lot of time to daydream. We didn’t have malls and theaters to keep us distracted. As I could save up my allowance, I built several of the Estes rockets, but I was getting bored with the single engine design of the rockets I was building. It was time to build something unique. It was time to build a much bigger rocket with a cluster engine. The largest engine that Estes made back in my day was the new D engine. I wanted to build a 42″ tall rocket with a cluster of 3 D engines. It was going to take that many of the new powerful D engines to get my rocket off of the ground. First, I had to find a cardboard tube large enough to form the main body of my rocket. I rummaged around in my dad’s garage. After searching for a while, I found an old cardboard tube that used to hold a special film that my mom used in her art work. It was the perfect size. Now I had to fashion fins and a nose cone. That was not going to be an easy task. I had to use lightweight balsa wood, but it had to be shaped to the perfect size. Shaping a cone is not easy, especially when you don’t have many tools. Somehow I was able to whittle the pieces down to the correct size and then sanding it with many sheets of sandpaper. I had to then build some sort of engine casing that would hold all 3 of the D engines. Scrounging again around the house finally led me to the freezer. A frozen orange juice concentrate can fit perfectly inside the body of my rocket. I then took the 3 engines, glued them into the orange juice can and slid them into the base of the rocket body affixed against the engine bulkhead. Now I needed a shock cord for my nose cone and parachute assembly. More searching led me to my mom’s sewing drawer where I found a piece of elastic for waistbands. Finally, I had all of the parts assembled for my first home-made bird. I took a can of silver spray paint to finally give my rocket the “official” look. A few carefully placed decals displayed “USA”, just in case it went into orbit and whoever found it wanted to know which continent it was launched from. Launch day arrived one beautiful June morning. That day our maid, Claudia was there. Claudia was more like a part of the family than domestic help. I brought the rocket out of the garage and she said, “What you gonna’ do with that thing?” as she started her trademark laugh. “I’m going to launch my rocket today. Will you come watch?” I asked. Just then my mom came in the room asking if today was going to be the day that I tried to launch it. “Yep, can you give me a ride down to the Eberwine field? I don’t know how much space I will need and they have a big field.” I grinned. “Ok, get your brother and let’s go.” she agreed. The drive to the field seemed to take forever, but we finally arrived. Launching a rocket wasn’t like launching a bottle rocket, you didn’t light a fuse, you used a remote launching system. I had constructed my launch pad out of an old 6×6, bored a hole in it for the exhaust and then used an old pole as a guide rod. As we got out of the station wagon, I carried my rocket and launch pad to a level spot in the field. I carefully attached the igniters to the engines, then ran the wire back to the car. Back in the 60’s we typically would use the car battery to provide the power for the igniters. “Ok, stand back!” I shouted as I counted down. 10, 9, 8 all the way to 1, then I pressed the ignition button. There was a great whoosh of smoke and fire. The rocket slowly lifted off of the launch tower only to reach about 100′, then the parachutes deployed and it was over. “What the heck!” I said as I ran to go get my rocket. I turned over the end of the rocket only to find that two of the engines had not ignited. What I had seen was the result of one rocket engine. Claudia just shook her head and my mom gave up a whoop thinking that this is all it was supposed to accomplish. “No, no, it didn’t work!” I complained. “It was supposed to go a lot higher.” My brother just shook his head as he walked back to the car.

Gill, Grandpa and Drew with my Silver Rocket

The next week, my grandfather from Alaska arrived to visit. This was his first visit to VA and I was so proud to have my Alaska grandpa in town for the next planned launch. I removed my orange juice can rocket cluster and replaced the spent rocket engine with a new one. This time, I made sure to carefully install the igniters while the rocket was in the garage instead of in the field. “Hey grandpa, would you like to see me launch my rocket?” I asked. “What’s that? A rocket? Are you going into outer space?” he kidded. “No, I built this rocket and I want to see if it will work this time.” I explained. “Sure, let’s give it a try.” he said. Again, my mom, brother and now my grandpa climbed into the Ford station wagon and headed again to the Eberwine field. After setting up everything like before, I told everyone to stand back and started the countdown. 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 IGNITION! I felt a lump in my throat, waiting for something to happen, then WHOOSH! All three engines ignited simultaneously forcing smoke and fire out the hole of the launch base. Then the engines thrust the rocket up immediately past the launch tower, streaking up towards the clouds. Higher, higher it sped as it reached apogee. It glided for a few seconds, then the ejection charge popped the nosecone of the rocket out allowing the parachute to unfurl. The rocket, only a small speck slowly glided back down towards the ground. I ran in the direction of the descending silver tube almost able to catch it as it landed in the field across the street. Cheers erupted from my grandpa, mom and even my brother Drew as they couldn’t believe that this assembly of household finds had defied the powers of gravity, even if only for a few moments. I came home that day feeling like Robert Goddard, the American rocket inventor. Now I had the bug. My next rocket project was going to be bigger and better than ever. I quickly found two old carpet tubes, one larger in diameter than the other, one being the booster and the other the second stage. This rocket stood taller than our two-story house. I decided to work on the payload section by leaning out the window of our second story bathroom window. My rocket was doomed to never see the launch pad. You see, I had reached the limit of what was commercially available in rocket engines. Combining three D engines was not recommended and I had pulled this off with my silver bird, but I would need an engine that would produce at least 1,500 lbs of thrust and that was something that was not just sold over the counter at your local hobby shop. I tried formulating my own gunpowder, but without the proper combustion chamber and nozzle, there was no way to make an engine. I tried using sheets of copper and forming a nozzle, soldering the nozzle to a pipe, but when it came to test fire the engine, the solder simply liquified under the heat of the gunpowder and my nozzle fell to the ground resulting in a smoking, stinky flame of goo. I was probably fortunate that the nozzle had fallen to the ground. I probably would have ended up with a pipe bomb and then not able to type this story. My rocket days were over, at least for 20 years. I did pick it up again later as an adult, but the realization that this wasn’t a cheap hobby nor one for the garage was becoming very clear. Neil and Buzz would have to go to the moon without me. NASA didn’t call to ask for my help either, but my mom was calling me to take out the trash. Yep, I was back to earth.
