When I flew Hercs overseas...it was three flt kits full of charts...remember each kit had three of everything. One was for US stuff..the other two had the rest of the world. As a new co-pilot I was PUBS officer for a few months.. Jesus H. Christ it was a pain making sure all the bags were current, and had everything they needed. 48 freaking bags... ( 16 assigned aircraft )... good thing was it was NOS charts so for the plates the whole books changed out.
