I think that is a very good question gaztop.
After many many years of doing it...I still don't have the answer.
Perhaps you may want to look up Pilot Officer JG MAGEE JR. ROYAL CANADIAN AIR FORCE and read his poem High Flight.
Actually I will post it for you

High Flight
Oh, I have slipped the surly bonds of earth
And danced the skies on laughter silvered wings;
Sunward I've climbed, and joined the tumbling mirth
Of sun-split clouds-and done an hundred things
You have not dreamed of-wheeled and soared and swung
High in the sunlit silence. Hovering there
I've chased the shouting wind along, and flung
My eager craft through footless halls of air.
Up, up the long, delirious burning blue
I've topped the wind swept heights with easy grace
Where never lark or even eagle flew-
And, while with silent lifting mind I've trod
The high untrespassed sanctity of space.
Put out my hand and touched the face of God.
Cheers...Happy Landings...Doug
