First two flights with B6-4 motors went well, so got adventurous and decided to put in a C6-3.  Flight was awesome.  The rocket headed towards the edge of the school building's roof, but the rocket drifted back right into the middle of the field.  The gliders, however, don't exactly "glide" and ended up over the edge of the field, right in the ditch.  Miraculously, both gliders not only missed landing in the water, but landed within a few feet of each other.
