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’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 But, again, I’m months out of date on that incident.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.


  • Kind of. It is more the same system, just some towers are operated by the military and some by the FAA. Each has their own airspace they are responsible for, but civilian aircraft can fly through airspace managed by military ATC and vice versa.

    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.

    Caveat: it’s been years since I’ve had to know any of this, so this might be outdated or misremembered.








  • Maybe, if something speaks to me. Downside of face tattoos is wrinkles. I’m middle-aged, and wrinkles are right around the corner for me.

    Right now a cute critter on my wrist would make me happy (and, side-benefit, keep me from biting my wrist when I get super stressed–no biting wrist friend! [I’ve tested this with temporary tattoos and it works for me.])
