I think the PM holds the power all over their so its not quite the same as if it happened in the US for example. Its still a massively bad thing loads of MP's and top as well as the top General's. Very sad.
Even beyond the massive loss of life this is going to effect a lot of people for a long time.
You have to ask why in 2010 are the top official's not only flying around in the same plane at the same time but also in one designed in the 60's.
