Big tunneling milestone!
For the first time, TBC has continuously mined in a Zero-People-in-Tunnel (ZPIT) configuration. There is nobody in the machine (besides the videographer), which is simultaneously advancing forward and erecting a ring (i.e. building the tunnel). Each full ring weighs ~24,000 pounds.
In the same way that full and rapid reusability is the holy grail for rockets, ZPIT continuous mining is the holy grail for Boring Machines. This is the safest, fastest, and least expensive architecture to build tunnels.
