I remember it from a youtube video from one of those engineering channels (might have been “real engineering”) probably a year ago. I only remember it because I thought “wow they have to have so many safeties” and that it is good to draw on parts and such instead of just relying on technical drawings.

I don’t remember, but it might not have crashed (multiple sensors), and it might not have had a latch/notch. But it was a long time ago.

Edit: I still remember the big yellow arrow.
