This event reminds me of a screaming horror of a serious incident about a decade ago at BCN involving an easy 737, lined up to go on 25 as it then was, and a foreign aircraft which landed over the top of it... From hazy recollection, the 'controlladora' lost the plot and cleared the other aircraft to land over the top of the easy, this being the only piece of standard phraseology in several minutes of RTF. Again, use of the local lingo was unhelpful as the non-Spanish speakers had no SA on the Spanish-speaking traffic. The fact that the landing threshold was displaced may have prevented catastrophe, as it provided some miss distance.
I've just tried to find the report on the CIAIAC website, but without joy. Can anyone point to it?
