A lot of people pass away at work....wonder why this one got singled out?
I can think of fairly recent similar issues involving bus/coach drivers and an airline pilot that attracted similar attention in the media, I think it's just something that had the potential to cause a lot of carnage in the eyes of the general public so people are naturally interested. Reassuring, however, to see that the safety devices did their job when required.
Also quite shocking that someone so relatively young and fairly well screened health wise should die in this manner.
