Members from all four teams traveled to the Maryland launch site on Saturday, March 19 to try to qualify for the TARC finals. The weather was cool (45f) and the wind was strong (about 12mph). We had major risk in landing in the trees, but decided to try some launches. We used both launch rails but angled them to create a little to cock into the wind so we don't reach the trees. 

Bob had built a rocket out of a Pringles tube. He launched to use up some F24-4W from lat spring. See the video. He didn't get an altitude from the altimeter because he covered the air holes with foam.

Objectives:

• Conduct one test and one qualification flight for each team.
• Fly the Pringles rocket

Lessons and Actions:

• The wind was a major problem. It blew rockets into the trees. It hurt our one TARC qualification attempt, which got caught in a tree 40 feet up. The extra hang time would have reduced the score by 5 points. We left the cargo unit from 9213 in a tree, although we tried to recover it with arrows. We tried again later in the week but still could not get it down. We went back on April 15 and we recovered it from the ground.
• No eggs were broken, so we must be doing something right with the egg protection.
• We had no copperhead igniter failures. We used several Quest igniters and had one failure. The Quest was easier to replace on the pad.
• Cutting holes in the chutes seemed to reduce the descent time, but we still had some floaters.
