If you just go to a flight school, all you're going to get close to is that school's planes. I worked line service while getting my private. If you can get a job in line service you can get up close to almost every fw and helicopter on the airport and talk with their pilots and mechanics. i fueled everything from Bell 47s to Hueys, Cubs to DC-3s and 707s, including Air Force 2. i got some good advice and some bad advice. But it was worth it.
