Just pondering this really. Hillsborough is often in the news (and not just because of a notable anniversary) but one rarely hears anything more about Piper Alpha (167 dead), the Marchionesse (51 dead) and similar. Why is this? is it because there seem to be unanswered questions about Hillsborough? or because it's football related? or both? or the ages of some of the people who died? or another reason?
