Atilla,
G-BCEA was certainly in the S Atlantic in 2000 when I paid a visit. I flew in her to some very windy/desolate places.
This was shortly after BIH took over the S Atlantic Contract from Bristow's, during which time the S61s they used down there were known as "Eric's"
I've flown in G-BCEB aswell, out to the Scillies when I was about 15 - that was a *long* time ago and I think she's still going.
