The obvious "visibilty" for this type of hot dogging is the tipping point for me. It is possible that this dare devil was awesomely prepared, and hugely experienced with this type of flying, viewers have no way of knowing. So the context is poor, and copycat wannabe's may be tempted into copying what they see with no understanding of what great knowledge, experience and precautions may have been applied.
The result could, and many timeshas been needless risk and destruction, which just makes our pastime look bad to the public, and costs us more in the long run...
