What happends when say a medical diversion happends? Is their a danger the crew could run out of hours? thus leaving the aircraft and pax stranded?
There is a danger yes, depending on how long it takes to sort the problem out on the ground, uplift more fuel, etc...
or vice-versa is 3 flight deck crew at VS
so there is some leeway with regard to duty hours, provided there was no significant departure delay. Crew can always go into 'discretion' (i.e. legally continue beyond their normal hours limit by a defined amount) in the event of unusual circumstances like that, though techincally they can always refuse.
In the event that the crew cannot go into discretion to complete the flight, no-one will be 'stranded' as such - the crew and passengers would simply be accommodated locally to allow a minimum rest period before re-commencing the flight.
I used to love the smell of Jet-A in the morning...
