I have two Estes Rocket Stories from my youth.
As a pre-teen, I loved to put together those model rockets from Estes. My dad always looked forward to seeing my progress. One day, on the way home from shooting a rocket off at the farm my dad and I discussed building my own rocket from materials that found its way home from his work place. A day or two later he brought home some materials, a tube, some wings and a nose cone one of his guys turned down on a lathe. I quickly got to the assembly and gave it a nice paint job. At the first opportunity we went to the farm, set up the launch pad and proceeded to get read to launch. I was giddy with anticipation of the launch with the family and some friends watching at a safe distance. I inserted the safety key and hit the launch button and what a display...the engine took off, but the rocket didn't. It would appear that the nose cone made of wood, the tube made from an industrial paper roll and the other "heavy duty" parts didn't mesh well with my homemade engine mount. The rocket was an epic fail as the engine set the toilet paper parachute buffer and the parachute on fire throwing that mess up in the air. The nose cone flew quite a distance all while the rocket fell over in what I remember to be slow motion. My dad leaned over in an effort to make me feel better and said "Von Braun's first rockets didn't fair too well either".
If memory serves me correctly in 8th grade we made CO2 powered wooden drag cars. We had a competition at the school in the gym and would shoot the cars off timing them for speed. The cars stayed on the striaght and narrow with two eyelets under the body and a decent strength fishing line stretched between the start and finish lines. My friend was a year older than me and we decided we would see who had the best car. We made a makeshift starting point at the beginning of a dead end street and a finish line at the rail road tracks at the end of the street. Inspired by Evel Knievel, but mostly since CO2 powered cars were for Jr High kids we were going to one up that by using a C class rocket engine. At the starting point, we used two cinder blocks as a blast shield with the heavy fishing line going through them. I happily agreed to let my friend go first, after all it was my engine and launch kit. Needless to say once the safety key was installed and launch button was pushed the car took off like a rocket. Tenths of a second later we realized there was no blast shield to protect the fishing line. The car went really straight for about 1/2 of the city block, then dove left under a car and got tangled up in a fence. A little old lady we used to visit from time to time stepped out on the porch and asked " boys what the heck was that" as we were running down the car, I yelled stay on the porch. You see, for dramatic effect I always got the engines with a few seconds delay before it would pop out the parachute. As we were running up the parachute deployment feature of the engine popped freeing the car from the fence and causing the car to land a few feet in the yard. The little old lady asked if we were going to do that again. While trying to catch my breath, my reply was no, my friend asked me "what, your not going to take your turn".
I have quite a few memories with Estes rocket engines. Hope I can make few more with their powder!
