I don't know if it has been posted elsewhere but I've been following progress of this in the warbird press. What the article doesn't say in detail is that Glyn Powell and his team have built an entirely new airframe to the original plans. All the metal fixtures, fittings, undercarriage, engines etc from an original Mossie or Mossies have been used but no aviation authority anywhere would sanction an original airframe flying due to deterioration of the glues since manufacture. Modern glues have been used to put the new airframe together and it should be at least as strong as the originals.
So what they'll have is a new aircraft with original fittings: that way it should last for years and keep on flying. This is only the first Mossie to emerge from this workshop, there's another in the works afaik. What I really want to know is when one or other will fly in the UK! Please please please please please.....
