Hey I was on the page for CRM, the helicopter group from the TV series. A couple things:
1. In the trivia, it says it's possible the helicopter Rick saw in Atlanta belonged to the group. I believe it was alluded that was the helicopter crashed outside of Woodbury. That was a group of National Guardsmen, unless they decide to retcon it.
2. Does anyone know if the guy Jadis talked to on the walkie when she was rescuing Rick, is it the same voice as the guy Isabelle talked to in Fear?
3. I'm just gonna guess now they're on a boat, something big like an aircraft carrier, maybe in the Gulf or off the East Coast. Helicopters are the only way to shore. And that's why Isabelle was after water purifying equipment.
