Wrong engine scenario.
Caroline's Eggscaliber Rocket with a D12-0 engine is bound to fail. One possible outcome of this flight is that the egg will break due to the lack of delay between the peak of the flight and ejection. The force vector due to the flight of the engine will be pointing up and will be large at this point, and the force vector then created by the ejection of the engine may cause a total force that is too much for the egg to handle resulting in a break . Beyond this, if the rocket is still flying up when the parachute ejects, the parachute may be torn from the rocket and then the rocket is left to fall to the ground with full force. A better choice may have been the C6-5, as this engine has a lesser thrust and a longer delay than the one she previously chose. However, I would recommend many other engines with a lesser thrust and a longer delay.

Some recommended engines for the High-Q Rocket are the D12-3, D12-5, E9-4, and the E9-6. The D12-3 Engine would result in a less powerful flight with a quick ejection. With the quick ejection, we run the risk of having the cone eject before the rocket has slowed down. The E9-6 would cause a powerful flight, but have a longer wait before cone ejection, which again may not be preferable if the rocket begins falling too fast before the cone would eject. An E9-4 is the most preferable engine for a clear and calm day. A D12-5 may also be a possible alternative.
