I've actually seen the QRA intercept over the horizon surface tracks down there, the first time was when the guard-ship (operating to the west of the islands) picked up a target using a radar on both its search radar and ESM systems well within the FIPZ. Both of the West Falklands radar sites picked it up as well and from what the computers were displaying on the scope it was at 2000 ft and seemed to be in an orbit. The Guard-ship ESM operator ID'ed the targets radar's as that of a C-130. Phantoms were scrambled, successfully locked on to the target with their radars which they thought was around 1000ft and called Judy. When they finally closed on the target they discovered it was in fact a fleet of Polish fishing trawlers!!!
