Informative speech on Helicopters
I. INTRODUCTION:
A. Attention Getter: Inspired by the flight of birds, even ancient humans dreamt of soaring at high speeds, stopping on a dime, and hovering in place, much like a hummingbird or a dragonfly. Every little boys dream is to be able to fly like a plane, I myself always had a fascination in helicopters. Helicopters are the most unique type of air craft in all of aviation.
B. Thesis: I’m now going to inform you on the history of helicopters and how the importances of helicopters have an effect on society today, according to Aerospaceweb.org on 03/11/12, Doug Jackson
C. Preview: First I will talk about the early beginnings of helicopters. Second I’m going to inform you about the significance of helicopters
Today. Thirdly I’m going to tell you about new features of helicopters that we can expect in the future.
