We have undertaken a long journey in this course. It is time to stand back and look at the big picture of aviation's rapid progress from its humble beginnings to the present day. From the perspective of your newly-gained knowledge, what aspect of aviation's history most interests you? Write about the economic, social and/or technological interactions with aviation. Possible topics include airline deregulation, social changes brought about by widespread air travel, and technological developments spurred by aerospace vehicle improvements, etc.
