D-HJFF - The "Barons" Helicopter
I have been immensely impressed by this thread and agree with many other comments that it has to be one of the best ever on PPRune. So I thought it was time to add to it do some digging.
I reckon the registration of the Jet Ranger mentioned in Savoia's last post was D-HJFF and was re-registered G-BTWA in 1978 in the name of Charles Hughesdon (of helicopter garden party fame) - source G-INFO. In 1985 it was old to a Greek buyer and registered SX-HBV and the website "Greek Helicopters" lists its subsequent registrations as N74EA and N624K. The FAA version of G-INFO lists N624K as a current registration, though Greek Helicopters also indicates that it may have returned to Europe as SX-HBV. As N624K it looks like it may have been in Latrobe, Pennsylvania.
Hope this helps others to perhaps provide more up to date or more detailed information for Savoia and perhaps some photos.
PS Got all this info from a Google search...amazing. Keep up the good work.
