Yes, I know how powerful the 139 is but it would still be worth mentioning an escape route since you need to get to 50 kts to be safe OEI iaw the QRH.
Did they do any 'Before-Landing Checks'? didn't hear them or a 150'call.....lots of chat about fuel and how things were either getting 'ugly' or weren't going to be 'pretty' but nothing that sounded like a professional helicopter crew going about their business.
