According to the article there was that problem at that time. Perhaps I should have said 'might' if it were to happen today, at the same time many things today have been kept hush-hush. It is lot easier to keep things that are obscure quiet, than it is to keep things that are not obscure quiet. This can be done by ensuring that they remain obscure. Greg H.
