CATO!  People had just told me how they liked/loved my Nike Smoke and go figure I use an old stock (stored well in my living room in a ammo container) Estes PSII DMS motor and it blew up on launch!  Rocket jumped off the rail and about 10' up apparently a section of the forward part of the motor exploded out the side of teh rocket causing a fiery spiral and then landed in flames.  I put out the fire quickly, but rocket is toast.  Motor also showed a burn line down the side of the motor.  RIP
