Little bit more on WK800’s history,
it served in the RAAF as A77-876, delivery date was 3 May 1953, 55 years ago tomorrow
in October 1960 it was converted to a D.21A before it was converted to a D.16 some time after its return to the UK
EDIT: i have spoken to some knowledgeable parties who have confirmed that WK800 has been heavily spares recovered for the MB Meteors, all airworthy spares have been removed and most replaced with lifex items, leaving an around 80% complete aircraft for say a restoration to ground running but it is far from flightworthy.
In answer to the question of remaining fatigue life, i was informed that it has consumed around 75% of its fatigue life, so there is still life in the airframe however there would be a massive amount of work involved in returning it to flight.
