Flight Log for 14 March, 1998, Boeing Space Center, Kent, WA

Overcast appr. 2500' AGL, wind 1-5 S (blowing away from fenced plant).
Model Flt 
Recovery Type Motor Comments
Bertha 24
12" plastic parasheet w/ spill and vents Estes D12-7 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 Estes 1/2A3-2T 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...
Nose-blow tumble Estes 1/2A3-2T This flight was exactly like the previous one, except that ejection occurred at the proper time, and the rocket tumbled to a normal landing.
Long Shot
Dual 48" crepe streamers Estes D12-0/Estes A8-5 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.
Bertha 24
12" plastic parasheet w/ spill and vents Estes A8-3 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).
