My dad shared a link with me to the Boeing 787 Dreamliner Flight Tracker (since removed), which monitors and displays all 787 flights across the world using Google Earth.
It doesn’t have a lot of practical use (unless you are looking for a list of all Dreamliner flights), but it is kind of fun for those who like playing around with Flight Aware. It runs on Google Earth and displays all Dreamliner flights and their position en route.
Here are two examples of United flights between Tokyo-Narita and Denver (currently over the California-Oregon border) and between London-Heathrow and Houston-Intercontinental (currently entering Ireland).
Finally, here’s an example of what it looks like from the passenger’s perspective. (This image didn’t change a whole lot. The views above were rotating around the plane the whole time, which was a little more interesting.)
