Ah yes, you have not been in the business very long if you have not
looked at a well soldered XLR or Jones connector then realized that you
have forgotten to put the rear part of the connector on the cable
first! Or remembered that you wanted to slide a big ferrite toroid on
the 3 1/8 inch coaxial cable before installing the connector. (Nautel
users will have probably done this)
And if you want the ultimate OOOPS read Richard Rhodes The Making of the
Atomic Bomb. The plutonium bomb used on Nagasaki was being prepped in
the assembly hanger. There was a very complicated wiring harness used
to attach all the explosive charges of the symmetrical exploders.
Someone noticed that the male and female connectors were at the wrong
end of the cable! The cable was routed in such a way that it would have
taken at least a day to remove and rerun the cable. So one of the
physicists along with an enlisted tech, against regulations (NO HEAT NO
OPEN FLAMES) said a sign in the room, unsoldered the connectors and then
resoldered them to the correct ends of the cable.
By the way that book is a wonderful read.
