John Daring gave us a call too asking to ferry the alleged Citation however, with a quick check of the registration it turned out to be a Falcon 900! I told John about this, knowing it was a scam but seeing how far he would go, and was told that they had just re registered it that day to the Citation. I told him that I used to fly the aircraft in question - some hesitations and a number of 'what's' and 'I can't hear you' from John but the end of it was when I asked for a COA and COR, he told me that he'd send them on within an hour. 4 days later and nothing yet.
