At Auckland Westpac Rescue Helicopter Trust's open day last week, there was a notable absence, to the disappointment of some of the children.
The chopper was meant to display a winch rescue - instead it was called away to the real thing. Such is the life of the service and all those who work for it. At a moment's notice they drop everything to help others.
As our three stories today show, sometimes it is those vital seconds that make all the difference.
They are all people with very different stories, united only by chance and the incredible work of the rescue crews.
And they are just three of hundreds of Kiwis who would not be here today without a service hugely dependent on donations.
