Airplanes
Personal
I love airports. My favorite thing to do is get a cup of coffee and sit a departure terminal and watch the planes take off. To me airplanes are a perfect example of innovation. The idea that I can get on a plane and in less than a day I can be half way around the world is amazing. The same type of trip only 100 years ago would have taken months of travel time.
The innovation we work on doesn't have to be a large, or game changing as the invention of air travel. It just needs to help one person.
