Well that doesn't prove anything. "Defence Contracts" have
probably posted that message to throw you off the sent. From looking up

Military Government department based at a notorious UFO investigation
centre in the UK, called RAF Rudloe Manor. No wonder they are trying to
make out there is nothing to see.
