On a related note, you uploading this test footage also helped solve what system was used in this video (www.youtube.com/watch?v=O26R...). The screen and alert tone here are near-identical to the ones in your footage! Thank you so much for preserving this system!

Hi! I admit I made this account to ask this, but I'm part of a community that's dedicated to trying to archive and document override systems like this one. Would you be okay with your video being reuploaded to YouTube for preservation? Credit and a link to this post will be given, of course. Thx!
