I was in PHL this past week, and I noticed for such a large airport with so much traffic there, the planes were being fueled using tanker trucks instead of fueling off a hydrant system. Though when I was on the plane I thought I saw the hydrant pits in the ground?? Do they have a hydrant system or was I seeing things?? I thought being so close to water maybe they couldnt put the piping in since it could leak into the water?? I know that is why MSY does not have a hydrant system. Could sombody please explain to me the PHL fueling operation.
Thank you very much
