With the extra flight crew, (you really don't want to go into the drink on your own...you'll get lonely before you die), all those extra litres of Jet A-1, All the food and drink you'll need, floats, survival gear, etc.........should get real interesting!!!
Cheaper and alot more common sense just to ship the big two bladed slapper's. Don't forget the small army of spare parts and the wonderful Bell reliability backup service. Oh, did I mention that a blade delamination on a Bell 222 is next best thing to a partial lobotomy without the anesthetic.....you could end up looking like Wayne Rooney on his wedding day!!!!
