What does it take to get food, medicine, emergency education, and shelter to record numbers of people in some of the most dangerous places on Earth? The UN does this around the world, including in Afghanistan, Haiti, Sudan, Ukraine, and the occupied Palestinian territory.

Boats, trucks, planes, and even drones help the UN get aid to people in need. If you've ever wondered just how aid supplies and relief workers themselves get to crisis-torn countries where they are needed most, it's the UN Humanitarian Air Service that steps in when no other means of reaching isolated communities are available.
