Many many people bypass the security theater, including TSA themselves not subject to the scanners. Ramp workers simply let themselves in through doors with keypads. Secure hardened doors to flight deck, along with better door procedures stopped the hijackings.
I've done a lot of work at a major airport and a few smaller ones. Ramp workers do have to go through metal detectors and have their bags x-rayed to get into the "sterile area". They do get to keep their shoes on and avoid the body scanner, for the price of getting background checked and fingerprinted every year. Some areas of the airport are further secured by locked doors. Some of those require a security badge in addition to a keyed entry, others a physical key or keypad just to keep the room separate from passengers and other tenants. Now there may be a way around this by driving in thru the back where deliveries are made and hangars are accessed - though vehicles are subject to search, I've never seen autos driven by badged employees getting searched - but driving thru the airfield from there to the terminals requires a special badge.
