Now sorry for the geeky-ness of this observation
But on FR24 there is an unidentified plane with the flight number CGOCX so in my sherlocking mode I typed it into google as C-GOCX and to my surprise it returned two planes with the same registration. One is a Eurolot Dash 8 (
here) with many a photo of it at Farnborough and the other is a Falcon 2000 (

Now as the flight left Luton and is heading out over the Atlantic it suggests that it is a Falcon 2000.
So do we have two planes with the same reg? I would have thought that was not possible. I stand to be corrected on all of this.
