We had a great showing at both the launch site and the landing zone. Lots of parents and families came out to support their kids with this awesome project. We have many people to thank. A special thanks to Sara Sherman and Discovery Horse for our wonderful team building activity. We could so the see the role this played with our kids from day one. Everybody had a wonderful and meaniful experience. They worked great as a team to accomplish this launch.

Thanks to Greg at BigRedBee Trackers. He is the maker of the trackers we are using. They worked like clockwork. We lost one tracker at burst altitude which was a result of the battery slipping it's holder. Easy fix for next flight.
