I’m a systems librarian in an academic library. I moved over the Lemmy after Rexxit 2023. I’ve had an account on sdf.org since 2009 (under a different username), and so I chose this instance out of a sense of nostalgia. I do all sorts of fiber arts (knitting, cross stitch, sewing) and love dogs.

  • I’ll cry all the way to the bank and doctor, what with my retroactive pay raise, my pretty awesome health insurance, and my liberal time off. We even got hazard pay during the early pandemic (if we were in a position where we had to see people in person).

    My union (AFSCME) bargains alongside the state cops. You might say it’s a union of unions. ACAB, but they get good benefits and never have a pay reduction. You can’t say that about most librarians.

    Edit: oops, just noticed which community I’m in. I’m in the USA and I’m not happy about our politics. Sorry to be an ugly American and assume that if your coworkers were anti-union you must be USAian.

    To quote myself

    I’m not sure why it is like that nowadays. I guess in the beginning of ATC in the US it made sense for air bases to control the nearby airspace, and it probably just went from there, with maybe consolidation of towers as a cost-cutting measure along the way.

    Also,

    IIRC, the Army and Navy also operate their own ATC Yes, there is also Marine-run ATC.

    Spitballing:

    • institutions don’t like losing control
    • Many towers are located on military bases
    • military air traffic controllers need to learn the ropes someplace that isn’t an aircraft carrier or active deployment

    No, like I said, they’re using the same systems, the same software, the same hardware. People at different towers talk to each other on the phone and on the radio, especially during handoffs between airspaces. The computers talk to each other. IIRC the information from one tower’s radar is shared with other towers. They’re not parallel systems, it’s all the same system.

    edit: I’ve been using “airspace” to mean “volume controlled by a tower”. There’s many airspaces.

    I’ve not read the report, but there’d only be one tower responsible for the airspace. Iirc, it was an FAA tower. What I heard happened was that the helicopter didn’t follow the tower’s instructions. But, again, I’m months out of date on that incident.

    Imagine airspace like a tray of cookies baked too-close together. Some are bigger than others, some are weird shapes, some are sugar cookies, some are chocolate. But it’s a tray full of cookie. There’s only one cookie at each spot.

    To stretch the metaphor further, imagine an ant walking across the tray. It’s still only on one cookie at a time and it doesn’t care if it’s chocolate or sugar. At the edge of a cookie there’s a handoff between cookies, where cookie A says “hey, cookie B, an Ant X is about to walk on you. Don’t let them crash into any other ants, k? They’re your responsibility now.”

    Anyways, I’m going to go let my caffeine kick in.
