I had a look at it and it worked for me. The airship was novel but I was not impressed with the overall concept which is no near competitor for other sims, let alone SS. Not even as good as the flight simulator now in Google Earth.
On a parallel note, there is a free Google Earth Plug-in system for FlightSim called "My FlightSim GoogleEarth" which is very good in that it enables your aircraft to be positioned at the correct height with a one minute marker for where it is expected to be then; it also places all AI (and MP user) aircraft in correct relation to your aircraft as well (in heavy air traffic 100 aircraft visible) all in correct position and updated every 3 seconds.
As a system it provides a vision radar overcoming heavy cloud and/or fog and/or heavy precipitation penetration. It is particularly useful for non-ILS approaches to airfields.
It is configured with three entries in Google Earth My Places consisting of 1) My Aircraft, 2) Other Aircraft, and 3) Spot Aircraft (the virtual position behind 'My Aircraft'.
It requires the tiny single purpose loop-back web server 'My FS Google Earth' which is configurable with simple controls for example positioning the height and angle of the Spot Aircraft with a slider.
The only other requirement is the 3rd party FSUIPC FlightSim Interface Plug-in which is a free download for non-commercial users.
So, why have I gone to some lengths to explain all this?
Well, I think that the concept would be useful, and simpler to implement within SS ~ Not that I am suggesting VSTEP should bother but it might be an interesting project for a keen SS user/developer and the result would be worthwhile in both missions and multi-user.
The tagging of course would be taken from the SS GPS Lat/Long readout and Heading.
The system is further configurable and easy to implement as well.
