The problem with preserving the wreckage is that there would have to be chemical treatment which the Environment Agency and the Countryside Council for Wales would have a collective heart attack at the very thought of it.

The only way to carry out the required treatment would be to remove the wreckage from the site before returning it to the site.

Other than that the wreck will continue to deteriorate at an ever increasing rate. That is because as the corrosion progresses the alloy struture begins to break down allowing the oxidation to occurr at an ever increasing rate until there is just powder, brass and steel left.

Either way it is better to be able to visit a substantial site on the hill.
