Great flight, rocket took a slight "lean" off the rail and ended up arcing over during the coast to apogee.  Heard a nice whistle on the way up which is not a "normal" occurrence for this rocket.  Rocket was nose up, still climbing slightly at ejection.  Good chute, long time coming down.  Rocket got noticeably hung up in a couple of thermals on the way down and just seemed to hang in the sky.  Landed on the field with no damage.
