A FlyOver (termed "Tour" in Google Earth) is a natural "addon" after spending the time to accurately design and plot out a particular Walk Section. It can be viewed by others in Google Earth but of course is far more accessible as a Video within an App. The result of rendering a Tour as a Video has been vastly improved in Google Earth Pro by virtue of MS Movie Maker being embedded as a tool, thus avoiding the use of "screen recorders" with their various shortcomings, so that is the method we now use.
