What is the maximum allowable angle from vertical for a rocket launch?

The maximum allowable angle from vertical for a rocket launch is set at 20 degrees. This limit is established to ensure that the rocket maintains a stable and controlled flight path as it ascends. Launching at a steeper angle could increase the risk of instability and decrease the effectiveness of recovery systems, such as parachutes, during descent.

By adhering to this 20-degree guideline, rocketry practitioners can minimize the potential for drift caused by wind and environmental factors, maintain predictable flight trajectories, and improve safety measures. This angle strikes a balance between achieving a strategic launch trajectory and maintaining control over the rocket's flight, which aligns with best practices in rocketry and is particularly relevant for amateur enthusiasts and certified launches alike.

The other options suggest angles that are either too low or too high, potentially compromising flight stability or increasing the risk of recovery complications.
