The organization that I work for, while not a relief agency, does have an aviation department which provides air support for our people in remote parts of the world. One of our helicopter pilots is heading to the Philippines to help with coordinating flights in a chopper provided by another organization. The chopper is being flown over in a 747 this week.
It's pretty cool to see how they do that. The partially disassemble the chopper (take the blades off), open the nose cone of the 747, and slid in the chopper. Looks like the 747 is eating the chopper with a grin on it's face!
