I thoroughly agree with your analysis and her judgment was probably skewed further by the fact she used to be a a rescue swimmer involved in real life-saving and may have approached her new job on HEMS with the same attitude.
If this was her first 'proper' job rather than sightseeing and basic instruction and she started in the HEMS business working for what seems like a 'cowboy' operator with a poor attitude to safety and weather limits - the holes in the cheese were lining up against her.
Not exactly definitive.
