I bet it can lift more than can fit in. Picked this up off a website somewhere. "Disaster relief may involve the airdrop of hay bales to flood stranded cattle or the evacuation of civilians from flooded towns as occurred at Katherine in the Northern Territory in 1997." Still nothing on how many the thing will hold. Let's say 300 people (same as a jumbo and standing room only).
480,000 divided by 300 = You are correct, All of them!
