I wince when I look at these photos. I wish all of you that have been injured the best of luck, and a speedy recovery. I have been lucky that I've never had a serious accident, I have had a couple close calls though. It makes you stop and think. I have seen a couple such accidents at our field. I too have flown alone, but will not in the future. If you see someone at the field trying to start a plane alone, ask if you can hold it for him. You may prevent an accident, and make a new friend at the same time.
Think safety, fly safely.
