Yes, the dad let the kid into the tower where technically he shouldn’t have been. But the infraction is minor. The dad told the kid what to say, the kid said it exactly and the dad went back to work. I don’t see how this was a problem.
As a kid I used to love going to work with my Dad. First because they had a breakfast cart that came around each morning with donuts, but second because I got to see some cool stuff. His work was the first time I saw Green-bar paper and a computer. (Think late 70’s here people!). At the time I thought it was cool, but I had no idea what it would be used for some day. Or that I would become a Computer Scientist in school. I also loved going to Tarrytown, which was where the research arm of General Foods was located. I got to try Pudding Pops before they were released and a couple of other cool things. (I later got a Summer intern job in Tarrytown, which was cool, except for trying the fat-substitutes that Entenmann’s was testing those days …)
I also remember one day, probably in 7th or 8th grade where I signed up for the ‘mayor for a day’ program through my Boy Scout troop. While I didn’t get to be the Mayor of Danbury (Jim Dyer was in those days, so no comments about me approving the Mall on swamp land), I did get to shadow the guy who ran the Danbury airport. I remember seeing the tower, where the planes were stored, looking at the lights on the runway, watching one of them get replaced. It was a really cool way to miss a day of school.
Honestly, when I heard about the JFK kid, I was jealous. I didn’t get to direct any planes when I was ‘in charge’ but I can only imagine how cool that would have been.
So as others have suggested, discipline the Dad and Supervisor, but don’t fire him. Bad enough the kid thinks he got his Dad in trouble, but can you image how he’ll feel if he gets fired?
