To classify this forum as 'nostalgia' would be to finally state that the Guppy is dead. Of course there is plenty of nostalgia, over 40 years of a type of flight operation rarely seen today inevitably produces a lot of war stories. The Guppy status is commercially operational.
Credit must be given to the guys with their faces pressed up against the chainlink perimeter fence. The perseverance of the Bournemouth Guppy Watchers have done their bit through PPRuNe, however small, in preventing the loss of this aircraft. Every movement is reported and understandably there is a lot of guesswork. It is being maintained in an airworthy condition so routine engineering activity will be seen from time to time.
I understand that a crew is on standby, but as anybody who knows about flight dynamics will appreciate, the weight of the airframe has to be equalled by the weight of the paperwork before it is capable of flight.
No Flight Plan filed for Australia it would seem.
