Falklands War PoWs

Hello All,
On 11 Jun 82 HMS Antrim, and RFA Tidespring were nearing Ascension Is having transported the Argentine PoWs from S Georgia.
They are stated (in “Island Base”, 2005, R McQueen, Whittles, 1-904445-18-7) as being flown back from Ascension to “Argentina” by a Dutch Martinair DC 10 (with the exception of Lt Cdr Astiz who was detained by UK authorities so that the Lt Cdr might face a trial, in wherever, for alleged war crimes during the Argentine “dirty war”).
Does anyone know the dates of this flight, the intended destination, and the a/c ident?
TIA
