Also one of the best and big grin parts of aviation IMO is breaking through a miserable overcast and rain into a brilliant blue sky with a dazzling white carpet of cloud beneath you as far as the eye can see, with rarely any company because the big jets are way above you and most other folk are plodding through the murk beneath you.
And the other is coming down through the cloud, looking at the ground beneath you, and spotting that you're exactly where you thought you were.
