I have a friend who has worked in US military black ops projects since at least the early '90s. And back in the mid '90s he told me there were aircraft being built and tested which had flight characteristics similar to those described here. This report is about a sighting in 2004, so it's more than possible that 10-ish years on, advances had been made that make this sighting quite believable. (edited grammar)
