I lost count of the number of times I almost said “shut the f**k up”.
Along those lines, I am ashamed to admit on one occasion, with my two (then) 8 year olds in the back of a Warrior, and my wife asleep in the front, as we returned from a visit to Leicester...
I had just switched to Cranfield to listen out for a gap in the r/t so I could call... passing through a shower, slightly poor vis etc. The girls in the back were carrying on a bit - teasing each other, e.g. "she pulled my hair", "no I did not", etc. (I'm sure all parents will know what I mean!). Annoyed that I couldn't concentrate and exasperated at being ignored when my shouts at them to "shut up" were ignored, in the end I resorted to "making my presence felt" by taking a swipe at them in in the back seats, whilst flying with the other hand. Didn't connect (of course - what do you take me for!?) but this eventually had the desired effect on the girls... but not a great affect on my flying!
Since then I prefer to fly whenever possible in an a/c which has an "isolate" function on the intercom
