we're trying to get them to fly tow... problem is, our Vne is below their Vs!
Thinking more about it, the feeling of freedom is probably the greatest. "Oh, I have slipped the surly bonds of earth...", that poem captures it all for me. To be free to explore a world of clouds at will, the peace and tranquility only found when spiralling down around a soft cumulus on a sunny afternoon... the view of a landscape where the sun has set, while you are still enjoying a sunset invisible to those ground-bound. A rainbow seen from above, sun glittering off a lake or the canopies of the trees in a forest.
As for pure kicks, as most people seem to home in on... stalls are an nice feeling. I for one don't mind having my stomach displaced. I actually enjoyed spinning as well. "Whoa, where did the ground go?!"
The feeling in a zero-G pushover... or negative Gs, hanging by the shoulder straps with the earth below you. That plays an interesting trick on your sensory systems, your ears tell you that your eyes are wrong and vice versa.
There is no roller coaster able to replicate that part of flying!
I thought I was doing good trying to avoid those airport hotels... and look at me now.
