AOPA has some ‘free’ options for ‘student pilots’. He may not be one yet, but aspiring to be, possibly. You should get Flight Training magazine out of the deal, which has simplistic articles on various principles of flight.

Give some thought to taking him to Airventure in Oshkosh the tail end of July. May as well show him where the motivations could lead.

If things get serious, give some thought to the family airplane, or access to one. We had a simple plane when the older Son was growing up, never pushed him one way or the other. It put him ahead when he went to training later on. Just put off that BMW, Escalade, and divorce, then you’ll have plenty for an Archer.

If he does pursue flying, you’ll have much to pass on without breaking a sweat.
