It is not surprising that there are ths many attempts, or that most of them are accidental. There are a staggering number of people flying, and a high number of guns in the US.
The Bureau of Transportation Statistics (http://www.transtats.bts.gov/) says there were 689 million passenger enplanements. You can do the math, but approximately 2,000 guns found is nowhere near a concerning number. It sounds shocking on the face of it, but with a decade of record gun sales and a strong movement for people to carry concealed, I expected for more to be found.
