I somehow manged to pass by the horse fascination stage that I am told many young girls go through. (I liked dinosaurs and space ships!). But I did read a lot of Greek mythology and the Oz books. Just enough suspension of disbelief not to wonder if horses could really fly or where the Deadly Desert surrounding OZ actually began.
The brief video below is just fun. It appeals to my love of mechanical toys and gives me an idea of how a flying horse might actually move while flying.
