I've been into aviation as long as I can remember, so I don't know where I started. As time went on, we bought small diecasts (not Schabaks like I have now) and later books. I started picking up timetables when I was about 5 or 6, and enjoyed flying (we did it constantly). We didn't have the internet until 1999, and at that time, the only aviation sites I knew of were the Airline sites, so when I didn't have an updated timetable, I'd see if there were any changes coming to flights into CMH, along with finding info about the planes, etc. I got the Royal L-1011 "Flight in the Cockpit" Video, and later, the Carnival 727 & Challenge 757 videos, which helped me out. Watching planes w/ my scanner while I was at airports (most commonly, CMH & SJU) got me interested.
More recently, airliners.net contributed a great deal!
