Fokker 50 for being brilliantly simple and yet a workhorse;
Fokker 100 for it's fabulously light handling, nice flight deck, and ECAM;
Boeing 737 for it's reliability and honesty;
De Havilland Dove for being a true pilot's aircraft (my all-time favourite);
Gazelle for showing me that rotary-wing flying can deliver on it's promises and doesn't have to be a chore;
PA-31 for taking me and my friends/passengers/family where we wanted to go at reasonable cost;
BN Islander for breaking all the rules and unbelievable field performance;
ATR72 for showing me how systems design shouldn't be done, but can be overcome, and convincing me that landing gear doesn't belong in sponsons;
Beech Baron for showing me that quality costs and pays;
CitationJets for being fun little machines (but I'd still buy a King Air 350!).
I could go on... It's been fun!
