I don’t remember flights in the 50s when I was a baby. I flew in 1972 and I didn’t notice much security added since seeing my father off on a number of flights in the years beforehand.
Even in 1979 I took my father to a flight where everybody had to walk through a metal detector to get to the gate area. I got the impression that a metal detector was the only thing used for carry on baggage, though maybe I’ve forgotten a conveyor and X-ray system.
In the years after that I flew often prior to 9/11. In one case at one of the NYC airports there was some construction going on in the gate area and only ticketed passengers were allowed to go through security to the gate area. I got some asshole in trouble who walked around the security booth while no one was looking. He did that because there was open space next to the booth and airline, airport, and security personnel were going in and out that way while a pair of guys checked IDs. Then those guys just walked away leaving the pathway open. Someone in a suit noticed shortly after came over and made a fuss about that open path around the security gate, told someone to block it off. As he tried to get things in order he asked a couple of people if they’d been through security and I pointed out the asshole who snuck past before. I was going on that plane, I didn’t want anybody on it who hadn’t been checked, plus I was pissed in general at the delay due more to the security people being lax than him.
I left lots of pocket knives in security. They would be in my pocket, briefcase, or computer bag normally and I forgot to leave them home or check them, and didn’t I did start buying cheap knives though. They never complained about all the other tools I’d carry with me, screwdrivers, needle nose pliers, wire cutters, all the usual stuff you might use to build a bomb on a plane but those things weren’t on the list.
I was carrying a portable computer early on in that game, and everything from 9-track tapes to floppy disks that I didn’t want put through the machines. At some point they were asking me to turn on the computer. If the screen lit up they said fine because they had no idea what they were looking at, but it didn’t explode right then and there so it was less likely to be a bomb than a computer that wasn’t turned on.
For a while I was also a technology smuggler, and started checking important items in luggage to avoid handling by security. I did like the idea they were focused much more on finding weapons and bombs than asking about the items in my luggage.
Then 9/11. I didn’t fly again for at least 10 years, and rarely since. I was tired of traveling anyway, and with all the added trouble I’m not eager to fly anywhere anymore. Probably will later this year for a trip just out of range for my driving patience.
