Thanks EDDIE.
I will check out that link shortly.
I haven't had Flightradar24 for much more than a year and for about half of that, the reg numbers and to/from routes on bizjets have been censored. Approximately concurrent with the rise of the media expression "the 1%", if you want to spin a conspiracy theory about it.
So, if you know the plane is a regular there, I take it that you are a local or know someone who is in the know. (Rhetorical, if you prefer).
