Terminal 4 in Barajas airport is brand new and state-of-the art (completed last February). This is where the explosion took place.

Here are some interior photos of the airport. From what I've been told, it is quite impressive.

The airport is nice and keeps getting better. Terminal 4 is the Iberia Airlines terminal, and that was probably why it was chosen. Iberia used to be the state-run airline. It's still a horrible airline, btw, although it is partially privatized now.
