Overall
You had a radio - use it throughout rather than shouting over a cliff edge! Bystander vs weak swimmer - which of these is your higher priority?
Casualty 7 - Injured swimmer with bleeding head
Hesitation to if you were getting this casualty meant no one ever did. Choice of torp at the very end was good. But unfortunately it was too late
Casualty 1 - Unconcious non-breathing child who has drowned
Bob known about but not seen Rescue was alright if interrupted, left at pool edge for a while
