I packed a parachute too tight in a little free one that came with an Estes. I didn't know it was packed too tight, put a C motor in it. It went up, turned, came flying back down without deploying a parachute and got lodged in the dirt. The body was destroyed in the impact. My little brother put an army man on a string connected to model rocket, it took off, flew until there was no slack left in the string and then started spinning like crazy two feet above the launch pad. The sad thing is, my dad works at NASA, and he was with us both times.
