And it would have only taken that lineman a few seconds to attach a 
grounding bond to the supposedly dead feeder and transformer before 
grabbing it bare-handed while speculating as to why it sounds like 
there's an engine running at constant RPM coming from the house 
connected to the service drop.

Serious accidents are often caused not by a single failure but several.
