I stitched together a small audio clip from LiveATC with both the Ground and Tower frequencies mapped to the Left and Right audio channels. It starts around the time the aircraft was cleared to land, and then skips forward to the moment the controllers realized the aircraft crashed.

Here is a link to the .mp3 file (it's on Discord for now - I don't know if this is allowed, let me know if it isn't):

Rehosted so it'll stay alive at least a few years: <https://lucgommans.nl/tmp/YYZ_Crash.mp3>. Let me know if you'd like something more permanent than my tmp dump folder, or a filename that gives credits or so! (BTW if you're editing clips, I can recommend exporting to Opus instead of ancient MP3: released in ~2012 so support is very good by now and it's like twice the quality at the same file size, probably even better for speech)

Hey, thank you so much. I shared the Discord file because I was sharing it with some friends, and then thought HN might be interested, but I don't have a more convenient place to serve the file at the moment. Thank you for hosting it.

Good point about exporting to Opus! I used .mp3 because the original audio files were also in .mp3. I've re-exported the file in Opus now, let me know what would be the best way to send it to you.

As for file name and credits, I think it's probably best to credit LiveATC (https://www.liveatc.net/), since that's where I got the original audio and I didn't really do much else beyond separating the channels. The specific files I used are the YYZ Ground and YYZ Tower recordings from February 17th that start at 1900z.

Contact method is in profile (or more directly: https://lucgommans.nl/email), though by now I can't edit the comment and thus link anymore so will have to post a new comment and kill the old link if we want to change it. Just let me know, all is fine by me

The discord link will die soon. The attachment links started expiring at some point last year IIRC.

It'll sort of die, you can't access them directly but if you take the link and paste it into discord (like one with just yourself) then it'll still work.

It makes sense, I don't suppose Discord is particularly interested in being a file-sharing site.

See the comment above about hosting the file in a more permanent way.

It's wild how calm and matter-of-fact he sounds when he says, "This airplane just crashed." I suppose that's the job though!

Listening to an ATC recording of a major accident is always a masterclass in focus and stoicism. Those folks are heroes.
