About this ebook

 Somehow seeing birds fly, makes sense to us.  But what about an airplane that weighs as much as an elephant herd?  How can heavy planes fly?  See inside this book for the science of engine push; wing lift; drag back and gravity down.  Moving air is the magic ingredient that enables flight.
