John,
I know it's not your fault, but Antarctica is a little further than 370 Kilometres from Australia, otherwise every man and his kangaroos would be there.
Also would have thought that you would be upto play with who has the contract and what machines, they are not AS350B2's,
kinda wouldn't be jumping to conclusions at the mo, everyone is trying their hardest to find out if they are ok, or what has happened, there is an orion over them at the mo, so just wait an see until jumping in hook line and sinker!!
hopefully they are ok, and thoughts go out to ALL PEOPLE involved!!!!
