For almost 6 years I have had an experimental mashup using the OTAP feed from the National Traffic Control Centre running. This feed is being closed down at the end of the year so my mashups based on it will stop working when this happens. If you don’t know what on earth I am talking about then this will most likely not affect you.
All other Google Earth mashups including ones based on the NTCC and BBC public feeds continue to run and are available to everybody.
