Heck...I had a whole Boy Scout Troop up in the tower at KMDW one Saturday. Late 90’s. I let my oldest son taxi a MX reposition flight across the field one day too. Took it from the gate to the hangar. Only after seeing folks in the terminal staring at a kid kneeling in the copilots seat waving at them did it dawn on me it might not be such a great idea. 🤷 Lol. Never heard a word. I’m retired and he’s a Captain himself now...so I think we pulled it off. Lol
