The US doesn't have horizontal directional drilling rigs that go under a runway and pull cable?

Even then, things occasionally go awry.

For an airport, the precision required both to not hit extant underground infrastructure and to know precisely where your newly deployed infrastructure is (for the next guy/gal to worry about) is probably a salient concern.
I'm not sure that horizontal drilling offers that degree of precision and assurance as opposed to rip-and-dig methods.
Any references / sources on that?
As opposed to the alternative described, where you close down the runway, dig out a full trench, lay a cable in a conduit, and attempt to compact every thing back to how it used to be?
You think that's a better alternative than just drill core'ing the conduit through?
Interesting.
