A new report reveals that an increasing number of people are trying to take guns onto airplanes.
TSA officials said since 2007, the number of guns found at checkpoints has been on the rise. Officials find an average of four guns a day.
Passengers are allowed to travel with a gun, but only in their checked luggage.
But even in when the gun is in the checked bad, the passenger must declare it to officials and place the gun -- unloaded -- inside a hard container.
The TSA said most people who try to carry the guns onto planes say they forgot they were carrying them.
