A Google Earth Helicopter (for v4.2)
It suffers from the image flipping when the corners of the pan gadget are approached, but it's still fun.
I snapped images from MS Flight Sim X and stitched a 360 pano, cut the windows out in Photoshop then did a tile cutting script to make the ImagePyramid
The range of zoom seems to be quite limited with this too, haven't figured what controls that yet.
I'm waiting to see the GE Microlight, GE Hot Air Balloon, GE Parachute and GE fantasy flying animal next
