Fate is the hunter..
I was on a business trip in The USA at that time, a family emergency occurred and I had to return home to Australia, the company that I worked for offered to fly me from Ohio in the company Saberliner to ORD to catch this flight, I thought this was too extravagant and declined, opting for an airline connection out of Dayton the next day....in 1973 in Sydney during my Commercial Licence training I had been enquiring about Instrument Rating Training at a flight school at Bankstown Airport, they offered me a chance to observe in a PA-30 but I had made arrangements to pick up my wife and declined the offer, the PA-30 had a mid-air collision with a deHavilland Dove, no survivors.....
