"...quite sure the crews rostered to fly CRAF or such are required by law to do so...." 
NOBODY at World "by law" is required to go to work! World is no longer a CIA proprietorship as it was during the Vietnam war days. If the company stops flying Air Mobility Command flights, then it would only be in contractual default; its pilots are not part of the military, nor employed by the U.S. government
