Twixy has finally begun flying. I love seeing it, I think it is so cool!. My only concern is that sometimes she misses her target or isn't able to hold Onto the intended target due to material. Maybe Im crazy but can't she get injured doing that?

Gliders are pretty resilient. Whether or not there's a risk of them getting hurt depends on what they are jumping/gliding to. If it is something hard it's possible, especially if they hit it hard. However, gliders weigh only 100 grams or so and most times a fall won't hurt them. Make sure there are no sharp edges or objects that she could injure herself on. Our gliders have fallen 6 feet or so after missing a target and were fine.
