I wonder what the possibility might be for the Morrow Project to have gotten there hands on a few old K-Class Blimps or even L-Class Blimps. Not very large but they could be used to transport supplies to out of reach teams or retrofitted with comm gear to extend comms range.
Might even make a good encounter for a Morrow Team to find someone using them as well. There essentially Goodyear Blimps after all.
