G-INFO shows current ARC to March 2020 so FlightAware records may not be up to date?
Certain words appear to have capital letters mid-sentence in various posts above where they are not really needed (placed as clues?): Competent, Machine, Controls, Accident, Investigation and Pilot so far that i've noticed.
Apparently single pilot if earlier posts are true, so someone (presumably) with an R44 rating or training for one - though why anyone would take their hands off the controls in a 44 (as appears to be alleged) is beyond me.
Also someone who has a security detail with them to 'whisk them away', and someone with contacts to stop all media reporting it seems!! Surprised anyone that important would be flying in a piston single (NOT Robby-bashing, i'm referring to ANY piston single).
Any more clues?
