Comparing power flying to gliding is in many ways like
comparing motor-boating to sailing.
Just about anyone can steer a motor-boat and make it go where they want.
Sailing a yacht, whether it be for pleasure or competition, requires more skills.
A glider pilot, on average, will generally have a more refined knowledge of the weather, better knowledge of aerodynamics, better decision making skills and a better lookout than a power pilot. They wont know the best way to start a hot wet lycoming but thats about it.
Gliding rewards the better pilot by better flights.
OOW cpla cplh GLIDER PILOT
p.s. you wouldnt believe how many airline pilots fly gliders in their spare time!
