This rocket with a DVR-808 keychain camera attached got stuck about 60 feet up in a tree stuck when it was launched on November 10, 2012. On December 6, 26 days later, it was recovered after the shock cord broke and it fell to the ground. The camera still works fine. The beeping sound is a sonic beacon from Adept Rocketry. It beeped in the tree for 3 days before the battery went dead.
