Danny, having been on aircraft several times (non-pressurized) when bullets DID hit things “critical to flight operation”, resulting in unwanted rapid contact with the ground, trees, and other inanimate objects, I wouldn’t want someone shooting inside a 757. (BTW, I believe Air Marshals use “frangible” bullets less likely to damage the aircraft, or non-targeted individuals.)
