An apology, going back to my previous challenge. Sabredog has correctly pointed out to me that I was incorrect in my identification of Tandil as La Base Aeronaval Comandante Espora de Bahía Blanca. Sabredog was therefore correct in identifying it Tandil. Please accept my apologies all, especially Sabredog, and I hope you will allow me to keep on playing.
(My excuse for misidentifying and posting it as Bahia Blanca was my bad translation of a Spanish language website, from now on I shall use Google translate and do my research properly)
