sure we walk on to the runway...but how is it different tells me you know nothing of how a club operates...we tell the other pilots what we are doing and wait to get a response from the other pilots that are flying...before we proceed on to the runway.....
perhaps you can fly as a guest, or get a month by month membership.....or if like my field it's city owned we make the rules, and you must have AMA membership.....but we can't stop a non member from flying as long as they follow the safety rules.....
I know you are 16, and the courts would probably do nothing to you in the case of an accident...but you would know that someone got hurt because of you if there was to be an accident.....think about it
