But, our ever protective TSA WILL stop you from bringing the smallest swiss army knife, complete with plastic toothpick, tweezers, tiny scissors, a 1.25 inch spear point blade and fingernail file with slot screwdriver. Your flying safety is their highest priority.
"9mm" is a unit of measure. The loaded cartridges that were fired at the Florida airport has not been identified in any of the news reports I have seen or heard. Such cartridges can vary significantly in terms of the construction and shape of the bullet and the amount of chemical energy provided. These factors all affect the results when the fired bullet hits something. The only thing they have in common is the diameter of the bullet--nominally 9mm.--and the shape of the cartridge containing the powder.
By the by, The 9mm parabellum cartridge was developed in Europe about a hundred years ago to produce results similar to the old police standby, the .38 special. Most police forces in the USofA changed to the 9mm because 'the 38 special was not powerful enough' What they really meant was they wanted to have more than six shots before reloading. The 9mm pistol designed by John Browning as an improvement on the .45 Colt auto pistol used by the US military (which in the military version usually has 8 rounds) the P35 or Browning Hi-Power, had 13 shots before reloading. Contemporary 9mm pistols frequently hold 18-20.
And lets not forget the projectile type. Hollow point, wad-cutter, metal jacket, etc.
All deform differently upon impact.
A quick search showed me a bunch more than I knew about
