Finally got the nerve to put a "J" in the Sonic Shark.  Great boost, straight and fast off the rail.  Arcing over at the top of the climb, heard the apogee charge but didn't see the event.  Several folks had eyes on it and eventually I was able to spot it as well.  Good main deployment at 500 feet.  Landed next to the away cell, the booster section clipped the irrigation rig on the way down with no damage sustained.
