Looking at thread 24, the Poly Tunnels, look far too small for a de-salination project, Quite a number of yrs ago, I visited the Mary Rose exhibit, and saw their de=salination system, ie, constant watering 24/7 365, for a number of years, and then there was the drainage of all the water to be treated and re used. However, I can see none of this in the Poly Tunnels, I realise that the Mary Rose was good old English Oak, and the aircraft is metal, perchance the set up at Cosford will be different?.
