I am no A-4 expert.
However, while writing a paper I joined a bunch of groups out of Argentina on Facebook. I can fumble through the Spanish and get what they are saying.
A lot of the pictures are pretty cool. However, this one is a little puzzling.

If you notice in the background it looks like the A-4 is being refueled through the air to air refueling probe. I know these were early A-4s, B models with some upgrades I think. Did an A-4 not have a normal fuel port?
