An individual launching a rocket must do which of the following?

The requirement for an individual launching a rocket to obtain proof of qualifications upon request is important for ensuring that safety standards are upheld and that only capable individuals are conducting launches. This aligns with the principles of responsible rocketry and public safety.

Additionally, launching only with Transport Canada authorization points to the regulatory framework that governs rocketry in Canada. It ensures that launches are conducted legally and that airspace is safe for all users.

Complying with rocket certification and qualification requirements is critical for ensuring that the rockets are safe to fly and that the launch is conducted in accordance with technical and operational standards. This safeguards not only the launch operator but also the public and the environment.

In summary, all these points are integral parts of safe rocket launching practices, which is why the correct answer encompasses all the stated actions as essential components of compliance with the regulations set by Transport Canada and the Canadian Association of Rocketry.
