A quick question. I was researching in the Argentine archives, and I find that some of the Vulcan departures (BB4, for example) were warned to the islands and mainland airfields.
I suspect the spy was the Primorye AGI deployed nearby.
Other info researched is about planes in ASI, and maybe the info came from a sattellite.
So que question, Vulcan crews expected total surprise over the targer (AFTER BB1) or they assume someone was spying in behalf the Argentines?
Best regards!
