Trislanders
I know Trislanders can be a pain in the neck, but some of my early flying lessons were on Trislanders and Islanders when I was a teenager in the Mexican Caribbean. It was a wonderful experience and I really love those planes.
I am dying to be on a Trislander again. It has been 3 decades since I was on a Trislander!
I will certainly be on one of those beautiful and elegant old noise birds of Aurigny (I love their piston propeller noise!), in July when I go to the British Islands.
