You could be running way too much power if

When I was the chief engineer for the KC-10 bed down at McGuire AFB, my hydrant refueling contractor was cutting up unused wires and cables from a manhole on the aircraft ramp and he saw 4 newish 3/4" coax cables that were tagged for removal. The contractor said to himself "these cables look like they're new, so maybe somebody made a mistake in tagging them". So he cut and carefully spooled them up just incase. Well when he cut them, he saw sparks flying, but he continued. That‘s when the guys in the RAPCON watched their scopes go black! Holy crap! McGuire was the FAA's handoff between Baltimore and NYC if I recall correctly. So all commercial aircraft had to immediately be rerouted around our zone - yikes! So after four hours of black screens, the Comm guys tracked the trouble down to our cut coaxes (the two main and two backup radar lines). (It was the same Comm guys who tagged the cables in the first place.). Well we repulled the cut cables and I called the FAA center in Pomona NJ to borrow some coax splices. When I turned them over to the Comm guys to install (the splices) they didn't know how to do it. Well, from my GWEN days at RCA/GE I had official Andrews connector installation training, so I jumped down into the dirty manhole in my business suit with one of the comm guys and I trained him how to do one. Then I had him jump into the other manhole and train another guy to do it (these connectors take about 15 minutes each to install), while I had another Comm guy join me in my manhole and I trained him how to do it too. When we fired up the radar, it came right back up. The wing commander was worried that he would be fired after that fiasco (he wasn't). Oh, those were fun days!
