An Early History of Flying Machines
  • Since the earliest recorded history, man has
    strived to conquer the air - to defy gravity -
    and fly like the birds. These dreams go back as
    far as the great mythological characters of the
    Greeks and continue today.
  • "Doing" is mankind's oldest method of learning.
    As we will see, the early pioneers of aviation
    worked with models to discover the principles of
    flight, just as we will do with our models.
