I’m not sure if it ever got going, last I heard the Mustang was still in America. Interestingly Flug Werke were threatening to start manufacturing Mustang structures last year but I haven’t heard anything since.

I’m not sure I actually agree. Many people are working long and hard to ensure that the standards of originality in vintage aircraft rebuilds are as authentic as they can possibly be.
These days it’s possible thanks to specialists throughout the world to rebuild to stock condition an aircraft from the smallest of sections (I’m not getting into a real vs replica debate). Specialists exist for amongst others, the Spitfire (Historic Flying), Hurricane (Hawker Restorations), Mosquito (Glynn Powell) and Mustang (Bob Odegaard and others in the US).
Aircraft that were considered junk a few years ago can now be rebuilt to as new condition and I feel that the effort should be concentrated in this direction rather than something trying to replicate an original but using different engines etc.
Vintage aircraft in the UK and I’m sure the world over are maintained to incredibly high standards and are no less safe than the average modern aircraft, accidents do happen however but I wouldn’t describe the attrition rate as high, but incidents are very often highly public.
I would much rather see an aircraft rebuilt to original condition than a new build replica.

This interests me, I understand that one new hanger has recently been put up and another is under negotiation with the council for a 7 year lease. However I will be writing my letter this evening. Harlow itself would be a better place for redevelopment starting with a large explosion.

I’m not sure of it’s current location, but it was in the UK 18 months ago, may still be stored. It was not Doug Arnold’s aircraft however but Flying A’s.
