Very cool project indeed!
I tried to check the kind of flights they flew in the world's dangerous airport (Lukla, Nepal)[0] and found they use ATR-72 series.

Re: ADS-B Exposed
#32We have a an ADS-B receiver at Summit Station in Greenland which we use to track airplanes that produce RFI we see in our experiment. I've considered sharing data (since nobody else seems to have data there) but the feeding instructions always scare me (run this script that downloads a bunch of random crap as sudo... no thanks). Please just give me a cURL command I can run... (perhaps some services have that, I haven…
ADS-B is easy to receive with an 'rtlsdr' and opensource tools.
Yeah we are receiving it and dumping it into a sqlite database per day, but we're not sharing it.

You can get containerized feeders for services like fr24 (e.g. liggy1/fr24feed) but that may not meet your requirements since it's really intended to handle everything from the sdr to the API, not siphon off data you are collecting some other way and then feed it.
Yeah I definitely don't want to run an opaque container either. We're already collecting and storing the data... I am happy to throw the data over via a udp socket or http request, but I don't want random software that we don't control running...
Re: ADS-B Exposed
#34I love how you can clearly make out the VFR EAA approach going into Oshkosh from Ripon. It’s only one week out of the year, but there’s so much traffic in that week that it still stands out.
Re: ADS-B Exposed
#35This is certainly missing some kind of legend explaining the colors of the lines, and what data is actually shown. Is "red" high or low velocity? And as an example, I do not understand what the "Boeing vs. Airbus" selection is trying to represent, as well as how "Altitude & Velocity" are supposed to be displayed at the same time. Project certainly requires a bit more care if any discussion should happen around it.
I see you highlight that, but I believe the visualization is designed to be intuitive once you interact with it a bit—no legend stricty needed if you calibrate against what you already know. Pick a flight you know (maybe one near yer home) and play with the options -- what patterns emerge? Red draws attention, “Boeing vs. Airbus” compares data, while “Altitude & Velocity” combines them. Explore hands-on; discovery of…

https://airplanes.live/get-started/ (other sites are corporate or have sold out [adsbexchange], happy to contribute reasonable costs to get a feed, no affiliation, I just like sensor feeds, thank you for the offer and consideration)
I appreciate the information! And yes, the fact that most sites are corporate makes me really distrustful of running random scripts from them.
This is sort of an example of what I'm talking about though, this script seems to install a bunch of random stuff but what I really want is an API to incorporate into our own recording process. As far as I can tell from a brief look, this binary (?) is downloaded from somewhere and run: https://github.com/airplanes-live/feed/blob/main/scripts/air... but I just want to incorporate it in the system we're using already when I finally get to improving it from a 10-minute hack job from when I set it up as a side project that ended up being really useful (https://arxiv.org/abs/2506.17522)
Re: ADS-B Exposed
#37Over in r/ADSB, someone recently posted a 3D visualizer of live ADS-B data: https://objectiveunclear.com/airloom.html. A nice alternative to the standard 2D maps we're used to.
Re: ADS-B Exposed
#38URL makes this sound like it’s supposed to be scandalous
I know! I think the creator, brilliant as they must be, is not an English native speaker. Or perhaps they simply enjoy the controversy / provocation heh :)
Eh I think the name kinda works from the perspective that it exposes patterns in adsb data. If you just glanced at adsb maps you wouldn't really see many of these patterns unless you stared at it for a very long time.

Boeing vs Airbus:
count() AS total,
sum(desc LIKE 'BOEING%') AS boeing,
sum(desc LIKE 'AIRBUS%') AS airbus,
sum(NOT (desc LIKE 'BOEING%' OR desc LIKE 'AIRBUS%')) AS other,
greatest(1000000 DIV {sampling:UInt32} DIV zoom_factor, total) AS max_total,
greatest(1000000 DIV {sampling:UInt32} DIV zoom_factor, boeing) AS max_boeing,
greatest(1000000 DIV {sampling:UInt32} DIV zoom_factor, airbus) AS max_airbus,
greatest(1000000 DIV {sampling:UInt32} DIV zoom_factor, other) AS max_other,
pow(total / max_total, 1/5) AS transparency,
255 * (1 + transparency) / 2 AS alpha,
pow(boeing, 1/5) * 256 DIV (1 + pow(max_boeing, 1/5)) AS red,
pow(airbus, 1/5) * 256 DIV (1 + pow(max_airbus, 1/5)) AS green,
pow(other, 1/5) * 256 DIV (1 + pow(max_other, 1/5)) AS blue
SELECT round(red)::UInt8, round(green)::UInt8, round(blue)::UInt8, round(alpha)::UInt8
The greener the pixel, the more Airbus planes there.
The bluer the pixel, the more non-Boeing/Airbus planes there.
The less transparent the pixel, the more planes in total.
White means all planes fly there, yellow means Boeing and Airbus dominate, red means Boeing dominates, green means Airbus dominates, cyan means Airbus+others, magenta means Boeing+others, etc.
