I have written on this topic quite a few times before and stated without reservation that safe flying is the norm and that crashes or incidents are exceptionally rare. And it has been proven that if there are mishaps, it is almost always a result of 5-7 events all going wrong. To buttress my statements and to provide you with outstanding, additional information on how to fly safely and to take the best measures possible to travel with the least worries possible, I highly recommend you read the following articles. Enjoy.
