(GGB smiles), yup, that's "the disease", LOL. Rarely does the person who has it even realize he does it. S14 has had it since he was a baby. S2 has it too. The others, not so bad. Based on my observation of my 5 boys, I don't think it is a boy thing, rather it is just an affliction that could strike anyone (actually I know a few female pilots who have it too). For the record, S14 is currently gathering plans to build his own airplane, and his career intentions are aeronautical engineering. He's even got his top picks of colleges already charted out, and he's only in 9th grade.
