Geek Alerts should be posted only when an aircraft or a flight is publicly announced or visible on one of the current flight tracking sites. Any military, VIP, or unannounced postings will be deleted until such time as the information becomes public or the aircraft has arrived at the airport. All alerts are for aircraft enroute or still present in the area or at the airport. For discussions on aircraft that have come and gone, please post in the General Aviation forums.
