Thanks Whirly, I'll store that for future reference.
I have to confess that 'fly' in this case means 'fly IN' not PIC.
I've not formalised a serious list, but I supose it would be, (in no fixed order):- parachute, paramotor, hang-glider, microlight, balloon, glider, prop (single to 4-engine), ditto biplanes, jet (single to 4-eng), hovercraft, helicopter, autogiro, floatplane, flying boat and supersonic.
Its the scary bits of cloth at the beginning of the list that I need to try, as well as well as 3 & 4 engined monoplane and biplane, single jet, anything that floats and autogiro.
