The 2023 Oscar awards featured a Best Actor and Best Supporting Actor who reinvented themselves and came back for a second act. The tunnel-boring machine Angeli is the LA performer who did much the same, but entirely underground.

The 22-ft-dia TBM in 2017 launched out of a 45-ft-deep pit in Little Tokyo, burrowing through an initial 400 ft of alluvium above the water table and only 5 ft of earth above it. Then it navigated a 600-ft curve downslope, tunneled through a local bedrock called the Fernando formation, passed beneath the Red Line subway and the historic Second Street Tunnel and close to batter piles for the Fourth Street Bridge.
