As a side note... There was a 22 year old young man that had MS since birth at a the show seated in, of all places, the crash site. Sadly he was on of the 10 reported fatalities. He graduated high school with top honors, and if I remember correctly, graduated college Suma Cum Lada (I appologise if it's not spelt correctly). He also had his own successful web hosting buisness.
Bill Wogan has been a longtime flightsimmer and member of flightsim.com (Pilatus96). Both he and his late son Mike suffered from muscular dystrophy.
My deepest sympathy and prayers go out to Bill and his family...
