St Johns is a good stopping point for C-130s transiting the Atlantic. It has good service from the FBO and comfortable accomodations for crew rest. It lies closer to the great circle routing than Lajes to the south and Keflavik to the north. It also has other options for alternates, ie. Stephensville, Goose, Gander, Halifax; than Iceland or the Azores.
