'It was like a little earthquake'
Sarah-Beth Casey, who had three small children with her in her apartment, saw the immediate aftermath of the helicopter crash.
– Sarah-Beth Casey, speaking to Sky NewsWhen I heard the explosion - it was like a little earthquake. It was like a gas explosion. I looked up to see debris falling off the tower. I can't see any people on the ground, it seems to be a lucky escape. The police and ambulance response was incredible.
