As word of their success spread, Jack and his team were approached by researchers and engineers from top institutions, eager to learn from their experiences and collaborate on future projects.
The phrase "hobby crack" hinted at the idea that someone had already made some progress in this area, perhaps even cracking the code on how to build a small-scale vehicle or model that could reach such incredible velocities.
As he delved deeper into the subject, Jack connected with other enthusiasts and engineers who shared his passion. Together, they exchanged ideas, shared their findings, and collaborated on designs.
Determined to learn more, Jack began to research and experiment. He spent countless hours studying the principles of supersonic flight, learning about shock waves, air resistance, and the importance of streamlining.
The day of the first test flight arrived, and Jack was nervous but excited. He carefully launched the aircraft, and to his amazement, it shot through the air, reaching speeds of over Mach 4!
The number "23" seemed to be a reference to a specific design or configuration that had shown promise.
It turned out that "Mach 4" referred to a speed of approximately 4,900 miles per hour, four times the speed of sound. Jack knew that achieving such speeds was no easy feat, especially for a hobbyist like himself. However, he was intrigued by the challenge.
