You are not alone - my two biggest screwups over the last 15+ years:
1.) Carboy Break - Washing a 6.5 gallon carboy in my double wash basin plastic sink. Had it resting on the divider in the middle of the sink, putting some water in with a hose in one hand, holding it with the other arm. Had a gallon or a bit more in it and it started to slip - slid down (not fast) hit the bottom of the sink, went straight through it and landed on my tile floor in my brew room. EXPLODED into the tiniest pieces of glass imaginable and I was finding them all over my basement. Hours of clean up, one lost carboy and a $100+ sink that needed replacing - although, Menards did replace that for free for me:)
2.) Just to prove you can F%$# up a bucket too - doing a 3 beer day with a friend. I brew on a three tier stand from More Beer - decided to boil #2 and #3 about 30 minutes apart on bottom burner and middle burner at same time. When draining the second level boil kettle, I set my bucket on a milk crate wedged between my brew stand and the wall of my brew room ( a couple inches off the ground). Left to grab my beer(not my first of the day) as the bucket was filling and just as I was coming back in, heard a strange sound and rounded the corner just in time to see the milk crate shift, and the bucket slide off with about 5 gallons of wort in it - dumped across the brew room and it turned into a “2 beer day.”
I too am now all buckets (except for long secondary when I still use carboys).
