The usual ho-hum perfect flight I'm used to from this rocket, but the
rocket traveled further upwind than expected, and landed on a barbed wire
fence top inside the Boeing plant. Retrieved by a working inside
the plant, only damage was a scrape on the trailing edge of one fin from
the wire. |

Nose-blow tumble |

Flight was perfect, except that there was no ejection, and the rocket
streamlined in from about 250 feet. Fortunately, the ground was soft,
BT-5 is sturdy, and I build on the light side; there was no damage.
I pulled the nose cone out of the ground, extracted the motor, and examined
it -- sure enough, the clay cap was still in place. MESS form filed... |

This flight was exactly like the previous one, except that ejection
occurred at the proper time, and the rocket tumbled to a normal landing. |

Launch, staging, and ejection were textbook, but the rocket landed
on a gravel bed under the radar test range, and the hard ground contributed
to a slight crimp in the body just ahead of the upper stage fin can. |

Low ejection and minor core sample -- parachute emerged too late to
fill and slow the rocket, but again the soft ground prevented damage.
I've noted that A8-3 motors no longer give good flights; I wonder if the
current batch of motors isn't a little weaker than the previous ones that
flew well in the Bertha 24 and Cherokee-D(2). |
