I think it was a 28D
He trained in them
Flew 84, 86, 100 and 104.....”104 a vertical beast but temperamental handling”
Wanted a 47 or 51
Too pricey
The 28 was 90 grand fresh annual
Big radial...14-1500 horses
Bright silver a pretty bird
Dad died with I think pushing 25,000 hours military and private hours...from 1955-1995
He loved it and was good at it....his personal business plane was one of the last Duke ever made...before that he and his partners had big corporate planes but the Duke was his baby he flew ...it was convenient
That’s a magnificent full aviation life that I could only dream of as an aviation enthusiast! Great story.
