I'd not noticed these images before, sadly they don't appear to be as well circulated as some others. You can see the debris on the helipad and lawn
pretty well and get an idea of the damage before collapse. It helps put things into perspective as well, you can see exactly how wide the area was
that got hit, definately does not look like the work of a missile or small aircraft.
