Despite the fact that after next week I will have flown over 50,000 miles this year, I am a nervous flyer at every take-off. The 2 flights I think about every time I take-ofl are that flight at ORD and the flight at DFW (probably in part because I was living in a Chicago suburb for the Chicago crash and had recently moved back to Chicago from Dallas at the time of the DFW crash). Wasn't the DFW crash attributed to windshear?
