Interesting. The one element which has me puzzled here, is that if an RAF fighter was photographed circling the object, why did the two poachers believe for even a split second that the MoD was curious to investigate the whole thing? Surely, there is zero chance an operational fighter would have taken off without the flight plan and details approved by top brass before that. Providing them with the photos and expecting them to investigate was at best naive, if not downright foolish.
Totally agree. Also, there were other reports of very large and totally silent blimps in later years (a domain of expertise that seems to have been Lockheed's), and so the notion of a very silent, low observable recce platform doesn't seem far-fetched, especially two days into the Iraqi conflict. Besides, nothing here says that the mystery object flew fast at all.
Which leads me to another question: what happened right after the photos were taken? Did the witnesses see the object depart slowly? Did they see it dash away? The way it disappeared from view would no doubt hint at the type of propulsion it used. Why does their testimony stop at the would-be "Harrier" circling around it? Surely, they must have seen both the aircraft and the UFO fly away, right?
