It’s happened again. Officials say another loaded handgun has been confiscated from a carry-on at Pittsburgh International Airport. Authorities say a weapon was found as a traveler was trying to pass through a T-S-A checkpoint early Sunday morning. The loaded 25-caliber handgun was found in a Crawford County man’s carry-on. Last year, officers found 34 guns at Pittsburgh International. This is the 13th time this year such an incident has occurred at the airport.
