Um, I spy journalistic "Chinese whispers". Jim Gray is not a Google Earth developer and has nothing to do with Google. First, the referenced report says Jim Gray "helped develop the technology behind popular computer mapping programs like Google Earth"; this is not the same as being a Google Earth developer. Secondly, the report itself is misleading; the "technology" mentioned refers to his work in database and transaction processing systems, i.e. fundamental database technology, which is presumably also used by Google Earth, and for that matter zCat's websites.
AFAIK he currently works for Microsoft in some capacity.
