A tailwind to be sure

If, like me, you were curious about what "disaster" is referring to, it's basically this:

The flight attendants are told to prioritize guard orders over prisoner safety (aka keep them in chains). And they have no evacuation protocols. If the plane crashes or people need to parachute out, the prisoners will be left for dead.

You get what you can. To me, this says they didn't break in very far.
