Matterport's SDK is so good -- I'm so impressed with the details like mobile performance the more time I spend building with it.

I did take some scans after the collapse! After we'd dug ourselves out and crawled out on our bellies, I went back with Polycam. The collapsed section we dug through was comparatively small, maybe 4-5 meters: Section 1: https://poly.cam/capture/4BB863F2-1CC3-46E3-8BDB-232EE3057BD...? (you can see where we crawled out to the intersection here -- the whole intersection had ceiling collapse, but only the section we dug out through was fully covered). Section 2: https://poly.cam/capture/3C5BB7BD-5FC9-4C00-AE1C-84E0544C51C...

We're just lucky it wasn't a rocky ceiling that fell, that would've been much worse.

The team taking care of the tunnels is doing an amazing job with the resources they have, and they're continually backfilling tunnels now and maintaining the ones that are there. It took us about an hour to dig out.

You can compare to the intersection in the matterport version in the same vicinity: https://my.matterport.com/show/?m=r5BR6K6Qxix&ss=338&sr=-.21...

I don't want to editorialize too much, but at that moment we were totally brothers--I was still early with Spanish, and the language, country, age differences fell away, and we dug ourselves out.
