If you read all the way down through the accounting information at the bottom of that page, you quickly learn that the cited page does nothing more than accumulate and tabulate the various reports and claims, many of which are highly speculative. FAS makes no claims as to the existance or non-existance of ‘Aurora’, but the accounting information & analysis at the bottom of the page provide a very good reason to doubt that an ‘aurora’ aircraft is actually flying in real service. The funding that appears to be available might support a technology demonstrator or two, but hardly an opperational aircraft fleet.
One way to determine if Aurora is in service is to look for the specially modified airtankers. If you can find them, then it’s in operational use. If they don’t exist, then it isn’t.
