One day one of her rockets flew, it didnt go very high but if left the ground
She worked day and night trying to figure out why her rocket flew, she soon realized it was the placement of the fins.
If the fins are placed unequivocal, tilted, placed not in the same place, it will effect your rockets flight
Make sure all your fins are placed exactly how you want and exactly how they should be. Make sure they are an appropriate size, shape, and the amount of fins. All of the affect the rockets flight pattern, and if one of these factors are off even by a little, your flight pattern could change drastically
Eventually she reached her goal of visiting the moon
