Q: I am coaching 5th grade. Can the payload (plastic egg) stay inside the assembly, or do you have to have access to it after launch to take it out and examine it?
A: As long as the egg can be inspected before the launch to ensure it is a full, unaltered, original egg then it’s okay. It must also be visible/accessible after the first launch if the same assembly will be used for a second launch.
Q: Does the payload assembly have to stay attached to the rocket at all times. Can the payload assembly with parachute come down separately?
A: The payload assembly can come down separately from the rocket body.
