I had a tech do that about 25 years ago. He went through a large beam and thought he was going upstairs. Solution: He pounded a 3/8" dowel through the hole and patched the roof with tar (in a caulking tube. I gave the customer a warranty on our work equal to the balance of the term of his new roof. No claim, still a customer. Still have the warranty letter in his file!

everyone had left, I was able to go back and tar the hole. Embarrassing!!
Mine was trying to drill up through a header into an attic, I was certain I was in the attic so I shoved the fish tape (30 ft fiberglass) up the hole so the guy in attic could grab it.
He kept saying he couldn't see it and I was dubious as I had to have at least 20 ft of tape up there. I decide to go out to my truck and get him a better flashlight.
As soon as I opened the door I figured out why he couldn't see it - there was the end of the tape dangling right in front of my face.
I tarred the hole and told the plant supervisor (was I not supposed to do that?). He had his maint super check it and he had no problems with the fix and said he would check it every year or two for shrinkage.
Back in 1965 or thereabouts I was drilling a hole for a wire from the outside of the house just below a first-floor window towards the inside of the house. I was mounting the bell box below the window. I eventually felt the bit turning, but not going any deeper.
I went inside the house and saw that I had drilled through the wall and had drilled into a cast-iron floor-mounted radiator, tight against the wall. I called my Dad, who drove many miles, saw my error, and proceeded with pipe wrench to disconnect the radiator from its feed pipe (don't recall ir it was steam or water). He re-drilled the hole, tapped it, and then with screw driver in hand he put a machine screw in the hole; moved radiator back into position.
His motto was "Never make a mistake you can't fix."
And there was the time I was in a basement whose walls were knotty-pine. While drilling with a two-foot bit at a slight angle but almost parallel to the wall I suddenly experiened water squirting at me from the wooden hole, behind which was a copper pipe. Dad to the rescue again.
Another time a customer called at the end of the day to say her clothes dryer was not working and "did we disconnect it?" No we did not, but the following day I discovered that in drilling a 3/8 hole from a first floor door to the basement the bit had passed through the center of the 220VAC dryer feed, and that we had also put a snake through the hole and our wire was now also passing throught the 220VAC line. I never felt a shock when the bit shorted the 220.
And there was the employee who couldn't care much about anything. He was the helper, who thought he new everything. He was in the basement with two-foot bit about to drill up into an interior wall. The basement ceiling was unfinished, no one was at home, the house was empty of furniture, the customer had just purchased the house, and the dummy was in the basement with this "lkethal weapon." Upstairs in the kitchen was the senior installer who was to stomp on the floor if he saw the bit come up through the tiled kitchen floo, in which case the dummy would stop and realize he missed the interior of the wall.

Why wasn't the lead tech fired? After one bad hole he should have taken over on the drill. He essentially taught the other guy it's okay to keep missing the target and repeatedly cause damage in the process.
When I was training others, they didn't get to drill on high-dollar potential for mishaps. I let them make their mistakes on shitty houses that an extra hole or two could be repaired or unnoticed. That means no tile, or berber loop carpet above at first.
The new guy might still be salvageable, given proper training. In a case like that, I don't see where the trainee can be blamed. The guy on top should have stopped after the first hole and do some measuring and finish it off himself (and taken responsibility for the damage).
I drilled through a coppe hot water heating pipe once.=20
The customer had one sliding glass door and had added another one about 10 = inches away with a small wall space inbetween. The first door already had a= wire to it and I figured, rather than running a new wire, I'd just drill t= hrough the short distance between the two doors and put them both on the sa= me z0ne. As I was drilling through, I felt some resistance and not followin= g my instinct ( because ..."who would EVER put a pipe THERE?) I just though= t I'd hit a nail.=20
My helper, doing something else in the basement yells up ..... Hey there's = water running down the wall where you're drilling!!!!=20

RHC; My son did much the same thing early on when he was still learning the installation side of our business. He drilled through a toilet drain while drilling down to locate for a keypad install. The client flushed the toilet and he got a facefull !!!!!!
Luckily, the stack was exposed in the basement and I was able to fix the plastic easily with a special plastic repair bond. But after I stopped laughing at him, I told him..."hey, this gives new meaning to the expression when shit hits the fan"
Needless to say, he's been super paranoid about drilling ever since.....:))

That's what they call "experience" ...... Isn't it?
Most installs I never had attic rat. I got quite good at reversing the bit, flip it and put a loop of wire back up. I'd make it a goal to go into the attic *once*, and grab all of them at once (with a Grabbit).
