There was work going on the lighting system:
- Switch it on.
10 seconds went by, then
- SWITCH IT OFF, SWITCH IT OFF
another 30 seconds
- It's OK, he's back on his feet now.
I did actually see the same when working GND at a Swedish air base.
Weather was CAVOK when the engineers arranged to start work on the approach lights. ......2 hrs later the fog moved in.
My slightly geriatric coworker on TWR turns the lights to 100% for a Gripen on PAR.
Que "KILL THE LIGHTS, FOR F**** SAKE KILL THE LIGHTS" (In swedish off course) in a high pitched voice on the vehicle UHF!
Apparently 440 volts trough the spanner is not good! (The guy made it with only minor burns, thankfully)
Much more fun over a beer in the mess, then 5 minutes after it happened!
