I've been there. Either controller forgot to hand us off or something caused us to fly out of radio contact. You then get your charts out and find a freq. to talk to anybody to find out what freq. you should be on. They shouldn't lose their pilots license for this.
I think the ATL FAA over reacted because of the media exposure to show how they are tough on pilot error. They have been punished enough already. Get them back in their pilot seats they worked so hard to get to and not make this a media show.
