Sad to say but this just happened to me a couple of months ago. To keep it a short story I'm in the back yard practicing. Those that have been here for a while know that I went to a thumb trigger release last year. Well I'm standing at full draw starting the aiming process when my son comes out on the porch and hollers at me. Well I lost concentration and instead of touching the trigger I turn loose of the release altogether. It made a loud twang and as far as I know my arrow is still flying somewhere in space and my release ended up 10 yards down range.
