Helofan, I think your question is pretty relevant to JJiimmbboo's situation so you're not highjacking the thread at all IMO. I don't think a six month hiatus will raise too much of a red flag at any interview, especially not if -as is the case with you- there's a very valid reason. Flightschools know that they're hiring people with woefully empty resumes anyway; that's how they get away with paying pennies.
In JJiimmbboo's case it's more of a question of a perceived lack of a go-getter spirit, but on the other hand; his post here shows at least some pretty good initiative!
