Goggles Flight Sim
Added to the mysteriously vacant Flash flight sim category, Goggles Flight Sim dares to let you go places where you may only have heard about.
In an effort to get a job, Mark Caswell-Daniels decided to create a Flash application that integrates information collected from Google's mapping service, which he had to figure out for himself, to attract attention to his portfolio. The result is this strangely alluring Flash flight sim with which you can fly around the globe to visit destinations of your choosing.
Once flying, control the play using the arrow keys; [left] and [right] to bank, [up] to climb, [down] to dive. But don't fly too close to the ground or you will crash. Use the [A] and [Z] keys to speed up and slow down, respectively.
The flight sim is still in beta form, so be forgiving of any wonkiness you may encounter, though it seemed to work almost flawlessly for me, save for a few missing tiles here and there. Have yourself a casual ride around the world, or hire yourself a talented Flash developer. Click.
Cheers to Brandy for the suggestion. =)
