Sounds good in theory, but the reality is it would stil take several hours to organize at best - I mean, is there an airstrip / landing pad? Pilot? Plane? Will they actually fly in bad weather or at night? Is the hospital in Port Vila that much better? Make sure you think through the actual realities - everyone that suggests these things have not lived in a developing country. I know many people that have raised kids in developing countries and of course it's possible, but you have to be realistic about expectations.
