Took my dad up a year ago for the first time, aged 97, in a plane he helped me to build. Never got a chance to take him up earlier in a rental as they lived on the other side of the country (Vic) so we didn't see them that often, but he always wanted to `help' with the plane when he came over (we're in WA). I had to cringe sometimes when his idea of acceptable practice was more suited to assembling a lawnmower than an aircraft, but it worked out OK in the end. Unfortunately, mum contracted Alzheimers about 5 years ago and died last July, so I never got the opportunity to take her up. Then dad also went last November, but I'll be forever grateful that we finally got to fly when I took the RV-12 over to Vic last March on its first big trip. Make the most of life's opportunities before it's too late.
