RE: Crashing - a part of the hobby?
Aviation is ruled by risk assesment. From the time you get your plane from its storage until it is back in storage you have to assess the risks. Everyone has a diferent level of acceptable risk. Those trying to be "the best" will accept a higher level of risk to better their bag of tricks. Others may have a lower level of risk. Some just plain don't assess the risk properly, or at all. As long as you are willing to accept the risk and don't impose it on others then crashes will be an acceptable part of flying. It is up to each pilot to decide.
