Sorry to disappoint - havn't gone away - just waiting for some technical info - am preparing a detailed post.
Didn't want to "waste bandwidth" responding to you on a point by point basis.
Gentlemen - please do not be put off from commenting by those on this site who seem to want to keep even the most basic assumptions "foggy"; the authorities could have made a much clearer starting point for debate 10 years ago but apparently did not want to - presumably, serving members who could clear points up are officially gagged - obviously this is a sensitive issue but the consequences for the British people of this disaster have been so serious that a fuller picture of what happened is required - this is only going to be achieved by reasoned debate between those interested people who can comment independently - errors are going to be made but with a more positive attitude much can be made of the available information to properly explore possibilities.
