Hey Doc.....we all know the saftey procedure's and that's the scary part. This can happen to someone who's been flying for a long time and considers themselves to be observing all the common sense safty procedures. With everyone being human it's easy sometimes to get distracted and do something that you really shouldn't do......Your absolutely correct in what you are saying about safty and i'm not disagreeing with you at all.....it's just that there is always that human element .....just my thoughts.....maybe I should get into model trains
