On Saturday November 22, a small group of rocketeers gathered for
a club launch at the park in White Bear Lake.
A few of the flights:
MASA members - please send in your thoughts about the
launch!

Quick tally
11 Cub scout flights
15 non-Cub scout flights
I had a mildly spectacular CATO of an older D12-3 in my Fat
Boy. I don't think this pack has been temperature cycled more than
what it got today. All the propellant ended up in the nose cone,
which is a bit deformed now. Cleaned out the casing without hardly
scorching it! Well, I can cut that up for centering rings now -)

Well it was cool and the wind was steady at 10-15 MPH and while
we considered the wind direction when we set the launch pads, 45
minutes later it had switched around by 30 degrees.
I did not launch anything larger than a B6-4. We only set up
only 4 pads, 1 MM and 3 low power ones. The first rocket was my
Estes CBU 87 and after a bonus delay, bracketed one of the other
pads with the 4 bomblets. Sorry Leif. Leif was out with his son on
his birthday and together had several nice launches. Glen's first
rocket was a tube fin, nice straight flight, long recovery. I flew
two of my Hyperion Clones for nice flights, long recoveries, with
even the separation landing safely with the extra wind float. We
had a den of Cub Scouts attend, each with a new Estes 13mm rocket.
We demonstrated rocket prep and launch procedures and they then
all launch their rockets, several separations but only one
missfire. A new igniter and that one also flew. One of the scouts
had also brought a Banshee which he launched on a C6-7 for
probably the largest motor of the day.
Glen had tried a D motor, but that resulted in a spetacular
CATO at ignition, with only the nose cone reaching any altitude,
20 feet maybe. My last 2 flights were the MASA Patriot and a Baby
Bertha (in honor of Alan). We closed the range at about 1100 due
to cold hands and feet, but then stood around for an hour
discussing the state of rocketry. Left before the snow started.
