Ergo: Captain Langenhahn was carrying his pistol with an extra, thirteenth, chambered round. He had to do a lot to put 13 rounds in his .40 caliber Compact. First he had to fill the magazine with 12 rounds and insert it into its bay in the pistol's grip. Then he had to pull back the slide, or top of the pistol, in order to chamber the first round in the magazine. This reduced the contents of the magazine to 11 rounds. Finally, he had to remove the magazine from the gun, fill it with a new "12th" round, and re-insert the magazine into the grip
The author that wrote the above passage should be fired from his job. That does not even come close to what occurs in an aircraft cockpit when an FFDO is arming himself. To pass on incorrect information (most likely obtained from someone wishing to sensationalize) is a disservice to the reading public and completely crushes the credibility of the author and the publication. I know that when you can't get facts many like to make them up but this is rediculous.
