Firefighters found a dead woman entangled in machinery Thursday in a non-public baggage-processing area at O’Hare International Airport in Chicago.
Larry Langford, a spokesperson for the Chicago Fire Department, said firefighters were called to the airport around 7:45 a.m. for a report of a person pinned in machinery used to move baggage. He said they discovered the woman entangled in a conveyer belt system in a baggage room.
Police said she was 57 years old but have not released her name.
The baggage room wasn’t publicly accessible, Langford said, and it’s not clear how she found her way into it. Scott Allen, a spokesperson for the U.S. Department of Labor, said an official with the Occupational Health and Safety Administration visited the scene and learned the woman was not an airport employee.
Looks like at some of their claims have the “door” for the bags that is plenty big enough for a person to crawl through. If that’s what happened, I honestly don’t know how you make a system that physically protects against it while still being flexible enough to handle any piece of luggage that will fit.

Sensors that stop the line when they detect something that isn’t baggage or a parcel?
“Sensors” sounds like a magical solution that hasn’t been thought through, but the marketing guys already sold it and won’t listen to the engineers explaining how difficult it is to actually build such a thing.
Companies use them in conveyor systems quite extensively. They can be used to detect anomalies, differentiate between different types of product, etc. the technology already exists, it would just need to be adapted and programmed to this specific use. Airports already use similar technology for baggage routing, although they’re scanning tags instead of image processing.
Lmao we have completely automated systems that irradiate food and medical products to sterilize them and bro thinks “sensor” is hand waving
Engineering is a real thing…
Haha you’d think in a community/platform of nerds, there’d be a bit more imagination, but oh well.
Muting! I have done a few safety light curtains before and it is really cool how they can tell the difference between a human and a pallet/part/etc with just lasers. There are some really complex safety scanners out there, such as the area ones, but it is neat.
The thing that would make this easiest is the direction of travel. If everything goes the same way around the belt, not terribly difficult to detect things going the opposite direction.
Main point is there are a lot of easy ways to prevent stupid, but stupid will still try and circumvent it.
I mean. It’s not magic. Even I could run a basic computer vision system from a raspberry pi and a webcam. They could easily come up with a system that returns confidence percentages for bags vs humans. Assuming the baggage isn’t coming in too warm, they could have an IR thermal camera that stops the line if it detects any temperature over a certain threshold. They could also use other tests, like two pictures a few seconds apart to see if something is moving on its own on the belt. I’m sure there are even more tests than the ones above, let alone design changes that could disincentivize folks doing dumb stuff, or making their dumb stuff easier to spot - like putting the end of the return conveyer behind plexiglass, so the person is visible on the conveyer before they disappear into the wall.
All of the above are not 100% solutions, but taken together, they can establish a reasonable confidence level they’re not about to intake something that isn’t a bag.
I see many comments discrediting this somehow, but I want to put my two cents in as someone who does work with sensor based AI assisted processing in real time and safety reliant environments.
Just because a concept can be thought of that sounds reasonable and maybe even works in simple tests, that doesn’t mean that it’s actually useful for the real use case. Many typical approaches to creating models that can solve computer vision tasks such as this can result in unstable results and no system that has a considerable false positive rate would be tolerated by any airliner. This isn’t even to speak of the false negative rate which might then still be rather high, which still leaves the system useless.
Naturally it’s not to say that no such system could be created, but they can’t be just whipped out like some people here claim. If, as people here are already assuming, the problem happened because someone climbed onto the conveyor belt and was carried in, then this type of problem is sufficiently unthinkably rare that most companies didn’t think about it much either.
Clearly greater security is necessary, but people are being unreasonable with how trivial they portray the solution as being.
