The last two flights I took, there was something physically wrong with the plane. The first of which occurred after takeoff (the landing gear would not retract), forcing us to circle at low altitude for about 40 minutes before landing; and the second required us to be grounded for about 60 minutes (a component on the wing needed to be replaced in order to pump fuel into the plane).

It doesn't give me much confidence in the quality controls of flying, but the fear mindset is much more insidious - and more importantly - in my own personal control. Whenever that mindset kicks in, I joke to myself that life has been good to me, and usually that takes care of things...
