I only started flying 2 years ago, and before I did so I was a little twitchy about certain aspects of the flight like take-off, turbulence, etc. However, now I've been flying regularly it doesn't even cross my mind that the plane might break! Especially in a light aircraft, the way it works just seems so simple. The only thing that's slightly worrying are the recent horror stories about ATC struggling to cope, but hopefully that'll be improved soon!
