Flight Anomalies for Allen Upward

Post-flight analysis of my LOC Caliber revealed that g-force had
pushed the 'chute to the bottom of the airframe (just above the
motor). The motor ejection charge seperated the rocket, but
was insufficient to eject the 'chute. "Tumble recovery" resulted
in two seperated fins.

The cluster flight of my LOC 4-29ss was unsuccessful due to the
ignition of only one of the H128s. The rocket flew in a large
arc away from the launch area and "pranged" at the far end of the field.
The two G35 airstarts did not ignite. Pre-flight preparation involved
testing/installing two ignitors with identical resistances, and wrapping a
bundle of thermalite around the pyrogen. The rocket had flown on this motor
combination and larger motor combinations 6 times before, with no failures.
An older reload kit failing to ignite and/or launch system's inability to
provide ample current to the ignitors possibly caused failure.

Type of rocket motor: AT I161W-10 (350 Ns)

Flight Anomalies for Mark Eisinger

Post-flight analysis of Mark's first flight of his
Caliber (H123) showed an enlarged hole in the forward
enclosure. The cause was determined to be 'blow-by'.
When the motor pressurized, a hot gas leak passed around
the delay and lit the ejection charge, resulting in
flight termination.

Post-flight analysis of Mark's third flight of his
Caliber (I161) revealed that the ejection charge had
fired, but failed to seperate the rocket.
