The pop of a supersonic shred, scattering fins below...
and the beginning of a sparky spiral dance in the sky...
Here's a rare catch of a fleeting midair moment - the forward retention for the solid-fuel motor has failed and so it thusts forward up through the rocket, pushing the parachute and nose cone out prematurely:
Even the little Estes motors can have a forward closure failure, with glorious results:
Sometimes the nozzle pops out the back, lowering thrust dramatically... and triggering premature separation and release of the smoke grenades:
The early parachute deployment creates an aerial u-turn...
and a convenient return close to the launch pad.
Clusters of motors offer more chances of a failure. With this one at DairyAire, one of the J motors exploded through its aluminum casing during airstart ignition. It ruptured the side of the rocket and blasted up through the body:
A fine family flying the flag for the Fouth. =)
The supersonic shreds spread the laundry in a yard sale in the sky, here with a Q motor CATO:
At times, it looks like an arcade game of Missile Command:
And makes you wonder the comprehensive policy on auto insurance:
