It is good to read the comments of others who are practical and apply good airmanship to a given situation. It is equally bad but not surprising to read the comments of others who merely resort to insults and personal attacks if their views are not the same as other contributors. It's easy to be rude and insulting on an anonymous forum; very brave. Take what you will out of the original post; perhaps there may be one item that provides food for thought. (p.s. "phase")
