When I worked on a Seismic Survey crew another lifetime ago the Vibroseis machine operators were all called
"Vibrator Operators"
Likewise the mechanics who worked on them were called Vibrator Mechanics.
More than one came back to work from leave sporting what remained of a black eye! And also more than one returned with broad grins and a happy disposition!!
You only live twice. Once when
you're born. Once when
you've looked death in the face.
