What happened in an airport in Spain in 1972? 73? Terrorist attack?

Question

My aunt was in an airport in spain and apparently terrorists attacked the airport (or something like that). It was in the early 70's, and I'm curious as to what actually happened there.

Answer 1

I was only able to find a couple of major terrorist attacks in Spain in the early 1970s. All were carried out by the Basque separatist group, ETA. In 1973, Prime Minister Admiral Luis Carrero was assassinated on Dec. 20. In 1974, this same group bombed the Rolando cafeteria and killed 12 people. This happened on Sept. 13.

Answer 2

Need better details. Lots of terrorist attacks in that time frame.
