What turns me on (while flying an aircraft) is the feeling the moment the aircraft gently touches the surface during landing. My best examples have been Wheels on the beach at the ocean, skids in the snow on a mountain top overlooking Vancouver, and the keel just kissing a perfectly glassy lake. Wheels on the bare ice of a frozen lake are also great. If the ice is very smooth, and you touch gently, you can be down and not even know it!
