Under poorly thought out directives this padlock shackle must rest across the trigger of every flight deck officer’s service pistol. This lock clearly causes accidental discharges. No trigger lock maker has ever made a device for use on a loaded gun. Using this padlock as a trigger lock was a poor and dangerous idea for anyone much less pilots of our air carriers. Requiring pilots to lock and unlock the padlocks on airplanes is very risky. The locks turn the FFDO's defensive weapon into a deadly booby-trap. Must someone be killed first? This is really very simple to correct by recalling the padlocks and ordering the FFDO pilots to quit using them. The proper way to insure that the pilot’s guns stay safe and secure is for them to keep them in a belt or shoulder holster at all times. That would end the unnecessary handling of the firearms altogether. It’s such a simple concept even a TSA director should be able to understand .
