See How it Flies

If you haven't read it yet, John Denker's e-book See How It Flies is a must read for all pilots, no matter what aircraft you fly.

While it was written from the persepective of a General Aviation pilot, it goes a long way toward not only explaining the basic physics of flight, but also how to apply some practical lessons to your flying. His description of energy management is a must for paraglider and paramotor pilots. Go read it, then read it again - it will make you a better pilot.
