I can't put it any better than my two favourite quotes..
"When once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been and there you will always long to return." - Leonardo da Vinci
"The cockpit was my office. It was a place where I experienced many emotions and learned many lessons. It was a place of work, but also a keeper of dreams. It was a place of deadly serious encounters, yet there I discovered much about life. I learned about joy and sorrow, pride and humility, and fear, and overcoming fear. I saw much from that office that most people would never see. At times it terrified me, yet I could always feel at home there... Though it was a place where I could quickly die, the cockpit was a place where I truly lived." - Brian Shul - "Sled Driver"
