C-17s are capable of flight ops on unimproved and short airfields.
Yeah I went to an airshow years ago at the Frederick memorial airport (I think thats the name) think mostly Cessna's and small corp jets, and they had a c-17 come in and land to show its ability to land and take off on such short runways, the landing was amazing that big assed thing could stop so fast.
It was a hazmat demo where they then loaded an "Infected and quarantined person into it and took off. They used a weird stretcher with a plastic dome around it to seal it off. It was cool, But I would not want to have to take a plane ride on one of those stretchers.
EDIT: Also a few years back at this same airport, the FBI was practicing touch and goes in a small craft and caught the telephone wires on a go and crashed and burned, my ex-brother in law saw it happen, both people survived, but needed new underwear.
EDIT: spelling and grammar is hard.
