Intro to AE

Dan Giarratano (gtg086w@mail.gatech.edu) “Why I chose Aerospace Engineering” I chose the field of Aerospace Engineering as my major for a multitude of reasons. First off, I love airplanes, or more accurately anything that flies for that matter. I find flight to be an amazing and miraculous feat in mankind’s existence. Simply Bernoulli’s principle of lift is an astonishing thing to me. I enrolled in Aerospace Engineering to learn more about what amazes me, and more about what I love. Truth is, I don’t picture myself ever being an Aerospace Engineer for a major corporation, my true love is flight itself! My dream is, and always has been to become a commercial airline pilot. People are always asking me why I’m taking up such a hard major when it doesn’t even lead me to the job I want at the end of the road. The answer to that is simple; I want to learn more about the tools of my craft, the nature of the beast so to speak. The second question people usually put before me is why not go to a flight school such as Daniel Webster, or Embree Riddell. The answer to that is a little less simple. I came to Georgia Tech for many reasons other than just my education. First off, I am enrolled in the Georgia Tech Drumline, and secondly, I am in Air Force ROTC. 10 years from now I see myself working my way up the pilot chain hopefully as a pilot or first officer of a private jet booking my hours working towards bigger and better things. 20 years from now I see myself flying much larger things such as a 777, or 747-400, but that’s just on today’s scale of large aircraft. I want to fly the biggest plane in the sky. If someone puts wings on a skyscraper, I’ll fly it! I joined Air Force ROTC in hopes of obtaining a pilot slot and possibly flying a C-5 or C-17. These are some seriously big aircraft. I decided on Aerospace Engineering because I want to know more about aircraft and how to design them, and how they work, and what they do. Sitting through numerous high school classes I was bored with History and English and other classes. I needed something I was truly, deeply interested in. At the age of 15 I worked at my local airport fueling planes. That was the point when I really knew that this is what I wanted to do with my life. I could honestly sit in an airport and watch airplanes all day and not be bored one bit, but my hearts content lies in actually flying them. That was another thing people have hassled me with in the past, why not be a traffic controller, you could watch planes all day? The answer to that is simple as well, I would be too jealous of the pilots actually flying the planes, and I would be a danger to the air community. I would spend all my time day dreaming and gazing at planes, rather than completing my duties as a controller of the skies and runways. Flight is something that I love and that is why I am an Aerospace Engineering student here at Georgia Tech! Some F14 Photos for your Enjoyment! haha
