Arresting gear wires rarely come apart. The wire is inspected regularly and before 100 traps is replaced. If there is a problem withthe wire or the motors, the wire can be removed quickly. If there was a problem with the arresting gear motors, them maybe that might happen, but more than likely the tail hook would come apart. The arresting wire is made up of more than one total wire. There are two sets of wires below the flight deck that are attached to very large pully and motor systems. The wires that come from below deck have two quick disconnects on the flight deck that attach to the wire you see on the flight deck. If there is a problem, they quickly disconnect the wire on the flight deck and use the other 2 or 3 arresting wires.
The tail hook is also removed before 100 traps and inspected. Tomcat and hornet tail hooks are made up of multiply pieces. The long tube that attaches directly to the aircraft and whats called a hookpoint which is what grabs the wire. The hook point is attached to rest of the tailhook by a large bolt. To have either an aresting wire or tail hook fail in the manner you ask about is rare these days.
If the wrong setting is set in the arresting gear pulleys and motors, one of two things will happen. If they put in too much weight, then the wire or tail hook could come apart, because the motors are trying to stop something that is supposed to be much heavier. If they don't put in enough weight, then the aircraft won't stop completely and go over the edge of the boat.
A good example of this is two rubberbands one is thick and one is thin. The thick one represents a high weight setting. It takes more force to pull it out. The heavier an aircraf the more force it has when it lands. The thin rubberband would be pulled out farther with the same force used on the thick rubberband.

That's easy to describe on the flight deck side. I still don't know all of the workings down below. What I have first hand knowledge of what happens below the flight decks is that it is very hot and very noisey, and if you every have a stateroom below a JBD, I would not blame you if you went insame and deaf. I almost did.

Back in the day I slept on the 01 below the bow cats. It wasn't all that bad compared to the aircrew berthing/staterooms on the 03. I hated walking to the 03 level ship's store during flight ops, I could only imagine trying to sleep there. Anyhow, as you mentioned earlier, I learned the in's and out's of air and surface warfare during deployments. There can be a lot of dead time. Maybe one day I can use it on Jeopardy.
However, there have been accedents where the wire came out of the engine room below decks and caused the aviators to "return the aircraft to the taxpayers." Happened aboard the USS Ranger back in 1992 (year?) I think. The cable parted several (10-15?) years back and wrapped around the island. I think they have worked out most of the bugs.....haven't heard of any in recent times...but we still thoroughly brief the parted wire/hook spit possibility!

Ahh ... memories of the piece and quiet aboard the boat ... our berthing was under the 3/4 wires on the 03 level, so we got the peaceful shotgun blast sound echoing through the passageways every 90 seconds ... and our shop. OH, that was a wonderful place to take a nap in between launches. Right up under the 1 row on the starboard side, so we felt like we were living in a vibrator during flight ops. Man, I can't wait for those state rooms! With how noisy I remember it being near the CATS, I'll go snag a rack under the wires anyday. LOL

Scrubex or cleaning the deck is done prior to pulling into port and on no fly days. The Kennedy did it every few days, usually after there is a crunching of a jet or two. It depends on the condition of the non-skid on the flight deck as well. If you have a good couple of layers of non-skid you are not going to need to do a scrubex as often. If you don't have many layers or there isn't any non-skid present (Kennedy) in the LA (landing area) then you do a scrubex all the time. Bare metal can get awful slick. How often they do a scrubex depends on the boat.
Each squadron must give up a few personnel to assist. Maintenance also stops to move the aircraft out of the way. Officer don't do scrubex, but you will get to do so many other unpleasant things I would not worry to much.
Our ready room on the Ike was right next to the LSO platform so we could hear power changes and aircraft picking up the ace (1 wire). On the Kennedy we were right where the aircraft would touch down if they caught the four wire, which happened quite a bit since the three wire was down for a long time.

I was watching one of those "horor of flight" (dont know the exact name), and it showed an A-3D snapping a wire, then rolling off the end into the drink! Of course anyone who knows the A-3D knows that it really stood for All 3 Dead, refering to the fact that their was no ejection seat and it was hard to get aboard(biggest operational carrier based aircraft of all time). Yay! ramdom trivia!
Anywho, when the cable snapped, you could see it whipping down about two deckcrew(while the rest jumped to miss it). Not good day for aircrew/flight deck crew for sure!
