According to NAR studies, the vast majority of unsuccessful flights fail because of:

• A. Rocket designs that are unstable
• B. Rocket motor malfunctions
• C. Recovery system failures
• D. Rockets that are structurally unsound

Answer: (C)

Recovery-system reliability is what most often makes a flight unsuccessful. Even a well-designed, stable, and properly powered rocket can be considered a failure if the recovery system doesn’t deploy or function as intended. The deployment sequence is the last line of defense between a successful recovery and a hard, unrecoverable descent. If the ejection charge doesn’t fire at the right moment, if the parachute or streamer doesn’t deploy, if the shock cord tangles, or if the parachute is damaged or packed incorrectly, the rocket can come down uncontrolled and be lost. That combination of factors is why data from NAR studies show recovery-system failures as the leading cause of unsuccessful flights. While instability, motor issues, or structural problems can cause failures, they occur less often in the reported cases. Emphasizing careful packing, correct ejection charges and delays, reliable deployment hardware, and preflight checks directly targets the most common failure mode and greatly improves overall success.
