Erin Rogers was waiting at a bus stop outside Vauxhall station when the crash happened.
It was a bit surreal actually. I just had a coffee in my hand, I looked up, heard a bang and saw bits of crane debris falling to the floor.
Then the helicopter was in flames. The rest of the people at the bus station were looking on going 'What was that?'. It's something I will never forget for a long time.
