"The Art of Paragliding" by Dennis Pagen gives a nice explanation of why paragliders don`t fall out of the sky until you put a pilot in one, easy enough for all of us to get to grips with without bringing Bernoulli, Botticelli, Ravioli or any other Italians into the explanation.
He also wrote "Understanding the Sky" - I`ve read it, and still don`t. But it`s good for a re-read, and explains weather in a fair amount of detail.
Me, I pull the string in, and the boat goes forward.
