Beyond the legal requirements on age for getting specific certifications, what do you think is an appropriate age to start 'formal' flight training?
Backstory: My 10 y/o is officially hooked on airplanes/jets right now. After his first trip to OSH with me, his older brother, and my dad in '22, the bait was set. After trip to OSH with my dad this year, he's swallowed it hook, line, and sinker. He's constantly talking and asking about airplanes. He has 'decided' that he wants to fly jets in the Air Force (my 25-year Navy veteran father-in-law has made it clear that Navy has jets, too). We fly an RV-10, which is obviously too much airplane for initial training for a kid, but just thinking ahead, there are a couple of glider operations within reach of here and the pilot community is big enough around here, we could start planning ahead a bit if this idea of him flying (in any capacity, even a lowly "I just fly for fun" like I tell the airline guys around here) seems to have legs.
