We traveled to our Maryland launch site on Saturday.  When we arrived, the snow was coming down hard, but it stopped by the time we were ready to launch. The weather cleared and it wasn't too cold.  The wind picked up for the last two launches. With two launch towers, we were able to get four launches completed within two hours. Here is a video around the launch site.

What we learned

• The launch rail worked great.  We should patent the design.
• Our special design flew very straight, with little angling.
• The basic thin-wall rocket required more angling of the launch rod, and it still went into the wind.
• Both rockets were heavier then planned. We are going to need bigger motors. The special design will need F50s and the basic thin-wall rocket will need F24s.
• We used separate recovery chutes/streamers on the booster and cargo units for both rockets.
• The streamer worked OK, but it got tangled once. We need to develop a loading procedure.
• We got some nice altimeter data - looked very smooth.
• We did not do a timed ejection charge, but we are ready to try in either or both designs.
