Flight Log for 10 October 1998, Boeing Space Center, Kent, WA

This was my flight for the Predicted Duration event at the first SeaNAR Sectional Contest.  The rules for Predicted Duration require that it be both the first flight of that model for the day, and the first timed flight of the flier for the day.  In compliance, I made a confident prediction of 35 seconds based on past performance of Spyglass 1.  Unfortunately, the boom only partly deployed (this has been a recurring problem with this model, apparently due to ejection crud that collects in the tube and adds friction to the system).  None the less, the model did glide, after a fashion, and the flight was ruled qualified -- but with an actual time of 11 seconds, my score in this event was much too high to be competitive (in fact, I came in last of seven entrants in this event).  Ah, well, on to D Egg Dur.

With a new parachute folding technique (folding the two parachutes together to reduce the likelihood of a single opening -- which made it tricky to fit the two parachutes in the Quest T-40 tube), and some masking tape on the motor mount to (hopefully) prevent ejection, I selected an egg from those that had been screened to meet NAR standards, prepped the rocket and motor, filled out the flight card, showed my motor to the Contest Director to confirm it was contest certified, and I was ready to go.  I put the rocket on the pad, wrapped tape on the rod to stop the pop lug at the top (thus pulling it off the rocket, and removing its drag), and when it was my turn, launched!  The ascent was perfect, with deployment exactly at apogee, and both parachutes opened quickly -- but the resulting time, 52 seconds, wasn't anything like good enough to place.  Ah well, back to the judging table, open the capsule, show the egg intact, and then off to prep again.

It took me several tries to get the parachutes folded together again small enough that they'd stuff into the T-40 tube, but once I'd managed it, it was off to the judge table again to verify the motor, and back to the pad.  Once more, the boost was good -- there was some wobble which I think was due to upset from the pop lug not separating cleanly -- and ejection close to apogee, but the time was even shorter.  The boost wobble must have cost me altitude, as the flight time on the second flight was only 48 seconds.  Meanwhile, a fourteen year old girl, Amanda Larson, had posted a time of nearly a minute and a half to win the contest (after moving up a division due to insufficient competitors in her age group) and set a new national B Division record into the bargain, and the second place flier, Michael Park (yes, the same one who owns Seattle Rocket Works) had take second place and the C Division record.  Of course, one reason we chose this event was because the C Division record was vacant (and it turned out B Division was as well), but times of over a minute and a quarter are reasonably good for the first time flying the event for all participants.  Next, time, watch out for me, the Egg Cone, and the super-chute...  B)
Spike (2)
18" nylon parasheet
North Coast F62-6 Dark Star
Contest over, there was time for one sport flight before the range needed to be taken down and the primary sponsor headed for home -- I prepped the Spike with an F62 (takes less than five minutes from decision until ready to fly), and carefully aligned the rod to vertical.  When the button was pushed, the rocket roared off the rod without a trace of arc, ejecting precisely at apogee for a perfect flight.
