Easy mitigation, don't let the same barcode board twice.
- asp_hornet 2y agoIt already doesnt. The problem is the operator
- raggi 2y agoNo the problem is that the software bugs regularly enough that conflicts are disregarded
- AlotOfReading 2y agoThese sorts of issues aren't always the software's fault. Sometimes it's human error. I've been prevented from boarding because the airline sent all the party tickets as a single PDF and my confused family members all scanned the first barcode they saw.
- raggi 2y agoSoftware fault. Even if they tried to do the right thing a barcode scanner has to be used while the screen and paper are not visible. We should have baseline expectations for UX thinking which are higher than this standard.
- asp_hornet 2y agoI agree with you 100%
- MVorlm 2y agoAnd like most security measures, humans are the weak link. The scanning system did mark the barcode as already used/invalid, but the staff assumed it was a glitch and let them on.
- fortran77 2y agoThey do. The gate agent overrode it. I hope they fire and prosecute him.
- codetrotter 2y agoWhy stop there? Execute him too while you’re at it! /s Humans make mistakes. You don’t need to prosecute every single individual that makes a mistake you know
- dathery 2y agoIt also creates a bad safety culture to over-punish mistakes, because then people don't report them for fear of being fired and the system can't be improved to minimize future mistakes.
- yareal 2y agoWhen things fail, we gain little by punishing the person who was operating the system. Instead, we must ask, "why did the system allow this failure?" Fix that root cause, because the operator is not the root cause here.
- throwaway35777 2y agoWhy did the system securing the plane let the operator override the error and allow an unauthorized passenger on the plane? Should be easy enough, UI shows the picture of the guy who scanned the first ticket and system tells operator you go and check his ticket. If you can't find him on the plane he's hiding in the bathroom, call security to get him out.
- firewolf34 2y agoStoring photos of people is a bit of a can of worms, make it even easier and just ask for ID if this error occurs.

- codetrotter 2y agoThey noted in the video that the system did say that the ticket had already been scanned. It probably happens now and then that a ticket is accidentally scanned twice and so this message wouldn’t seem that out of place, and so they probably proceeded as normal without thinking that someone else really had already boarded with the same boarding pass.
- dmux 2y agoI would think adding a simple timestamp to the message would be helpful instead of just a Boolean “has been scanned” type of flag. With the timestamp you could at least say something like “this ticket was previously scanned at <time>.” Then from that message you would know whether it was an accidental double scan (the time being within seconds of now) or whether some time had passed, which I would hope would raise an eyebrow. Edit: I have no idea what the actual messaging looks like. It could indeed have a timestamp. I’m just hypothesizing.
- bombcar 2y agoEven that’s going to have many more false positives and be annoying which will cause the attendants to be tempted to hit the “it’s fine” button. For example, I suspect a decent number are couples/families that print multiple copies of boarding passes and two accidentally try to use the same one.
