Interesting report from Editor of Scottish Sun who witnessed the descent. Can't help but think this could have been a whole lot worse but for a fairly hard landing followed very shortly after by a roof collapse. That junction is well covered by CCTV so I've no doubt the events will be well documented.
Gordon Smart, editor of the Sun's Scottish edition, saw the crash from a multi-storey car park nearby.
He told Sky News: "I thought it was a plane that was going to crash. I looked up at the sky and I could see the helicopter falling, tumbling ... and then there was an eerie silence for the last part of the fall.
"But the thing that was disturbing and shocking was there was no explosion. I couldn't understand why a helicopter would fall from that height and not explode. To see the angle, the speed and the trajectory of the fall ... it was a horrific sight."
