After some time spent in rest and relaxation goes by, word comes down, through secure channels ("open channel D" is the key phrase, to be specific) that the United Network Command for Law and Enforcement has granted exclusive use of the captured airship to the adventurers. They will, of course, deny any connection to it through their front as a charitable organization. ("Just keep us informed of any THRUSH activities, via this channel.") The adventurers will be allowed to maintain the vessel at whatever base they like, and name it whatever they please.
All seems quiet for a while, as the adventurers ready themselves to face even greater challenges than before.
