YouTube is one of the best tools to share video's and media with friends and the world. I can use videos that others have already made to emphasize the importance of a topic. It not only saves time and effort, but also adds dramatically to a presentation.
As you can see in this video, it shows just how skilled the Australian Air Force (RAAF) really are. Using footage such as this not only helps reenforce the point of technical accuracy and responsibility of their job, but also the pure beauty of some of the maneuvers they perform in the air.
