at first this flight looks like a success

but in reality it was a pure luck

and it almost never happened my name is Natsa

and I will explain you why I had to launch this giant rocket by hand

while it was fully pressurized and how two of my mistakes actually saved the whole project.

All started in April 2026 when I was watching the Artemis mission on its journey around the moon.

I looked at that huge SLS rocket.

wow it's amazing i had to build this rocket

but here's the problem i knew practically nothing about the rockets

so i started at the backyard with my kids and simple water bottle rocket It was fun,

but I knew right away that I wasn't going to stop there.

So, before building the SLS rocket, I started developing and testing the systems I would need.

First, staging mechanism.

I used the same mechanism to develop a booster parachute release system and tested that too

next came the Orion capsule with its parachute deployment system

and a time to release I dropped it from an rc paramotor just to see if everything works okay

and finally i built a fully functional launch aboard system

so step by step i was turning ideas into working mechanisms honestly the 1 to 30 scale

and 3 .4 meter height came from the size of cheapest cola bottle I could get.

The booster size.

The booster is exactly one bottle wide and one and a half centimeter styrofoam around it.

I thought the project would take me one or two months

but it turned into a five month of hard work developing and testing.

I actually choose the hardest way to do it.

Everything on my rocket works 100 % mechanically.

No electronics at all.

Mechanisms are triggered by a drop in air pressure and preloaded springs.

Simple and reliable.

Luckily I've been building RC parachutes for over 25 years so designing all 10 recovery parachutes was the easy part.

Someone asked me, Nace, the rocket is in the air only for a few seconds.

Is it really worth five months of work?

Was it worth it?

What do you think?

Put your comments below.

Of course There were also days when I got stuck and simply couldn't see a solution.

Sometimes it took many attempts before I finally got things working.

I also built a huge wooden launch tower in the same

scale 1 to 30 as the rocket with moving arms to make it look more realistic.

The launch tower also has built -in water tanks

that automatically fill the rocket when I connect the air supply

so when i finally put the complete rocket on my homemade launch tower

the feeling was incredible it looked amazing but i had one more problem i had no calculations for stability or aerodynamics.

I had basically built a visual 1 to 30 scale model

and I had no idea if it would fly straight or start spinning like crazy.

So let's find out.

But you can test monster like this in a backyard, right?

I needed safe airspace, a large open area with no trees or other obstacles.

I managed to arrange the lunch after the official program of a rocketry competition in Krško.

A big thank you to the organizers.

The plan was simple.

At home, I practiced setting up almost the whole system in about an hour and a half.

So, I added another hour as a safety margin.

We arrived at the lunch site four hours before the planned lunch, but even that wasn't enough.

I had a checklist for every step of the preparation at first I followed it carefully

but as I got behind schedule I started relying on my memory and

that was a big mistake I mean what kind of idiot

stops using a checklist in the final minutes after working on a project for five months

I had some trouble stacking the Orion capsule

and the launch abort system on the second stage so I had to repeat it several times.

People were already waiting for the launch so I was under a lot of pressure.

With some difficulty I finally secured the second stage to the main body

pressurized it with air and removed the safety pins and then i heard a strange sound from inside

like the sound of a parachute spring winger list here's the second stage parachute it was trapped between stages

so it couldn't get out but because i was

so stressed i simply ignored the problem

when i thought everything is ready i switched on the cameras well almost all of them

and my youngest son was in charge of pulling the launch trigger

but when he pulled it nothing happened the trigger was overloaded

because of the air pressure okay it's me again i had never tested the rocket trigger under the real pressure

Another mistake.

I ran to the launch pad and checked the system.

Everything looked ok, but then I heard another sound.

The air was leaking somewhere from the rocket.

I can't wait any longer.

If I wait, there won't be any launch today.

I crouched down to the trigger and pulled it as hard as I could.

The rocket launched and sprayed me with lots of water.

When I looked up, I saw that the two boosters had not separated.

They were falling down together with the core stage.

And the core parachute opened only about 2 meters above the ground.

The other sections separated normally and opened their parachutes.

20 seconds later it was all over.

My son brought the booster and the safety pin back to me safety pin, safety pin.

I immediately realized what had happened.

I had forgotten to remove the booster safety pin before launch.

It was clearly written on the checklist.

The checklist I had stopped using.

I had also forgotten to pressurize the booster parachute ejectors.

So even if the boosters had separated their parachutes would not have opened

when i checked the footage at home i noticed something else the second stage parachute opened immediately after separation

that was the spring sound i had heard earlier and

because of that the second stage didn't reach the higher altitude

but because the parachute opened so early the onboard camera captured this beautiful shot.

I would say, another lucky accident.

oh gosh i had so many lucky accidents already so the final results the core stage survived

100

A little scratched but completely useful.

101

The boosters were undamaged.

102

I also found the air leak I had heard before launch.

103

It was an o -ring inside the left booster.

104

The second stage survived, the Orion capsule survived and the launch abort system is in a perfect condition.

105

So for the next flight, first I will improve the launch trigger second i will have someone next to me with the checklist

106

and someone else will be responsible for the cameras subscribe for the next flight

107

and if you want to support my channel

108

and future project you can do so on my ko -fi page

109

and a very very special thank you to my wife

110

for supporting me throughout this project and to everyone who helped along the way thank you so much

이 영상으로 연습하는 방법

먼저 말하지 않고 영상을 끝까지 듣고 모르는 단어를 적어 둡니다.
보통 속도로 한 문장씩 섀도잉하고, 화자의 리듬과 맞을 때까지 반복합니다.
자신의 목소리를 녹음해 원본과 비교하고, rocket, parachute, trigger 같은 단어에 특히 주의합니다.

쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법

쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
