Yes a B777-200ER would be able to get in and out of Phoenix Field at McMurdo.Can a B777-200ER get into and out of Wellington with a useful load?
Can you land a B777-200ER at McMurdo?
These have got to be two of the baseline requirements.
If the answers are "yes", then a couple of these airframes might be a very attractive buy, because they'll be written down to about $0 in Air NZ's books.
Maybe splash out on a third and outfit it as "Kiwi Force One"? LOL
If a B777-200ER was flying in and out of Wellington will VIP PAX and their hangers on, plus media, the answer would also be yes because it wouldn't be operating at anywhere near full capacity.
I would suggest that if we went down this road, we should go with three because our experience with the B757-200 Combi has shown us that two isn't enough, from an availability point of view.
I saw a comment elsewhere that this won't happen because they are to big and couldn't operate out of Whenuapai, being restricted to Ohakea. Well same was said about the P-8A, yet we got them. More to the point, I think that people who believe that have muddled thinking, because if we replace the B757-200 Combi with a B767 variant or an A330 variant such as the A330MRTT, the same argument applies. Even the B757-200 Combi cannot operate out of Whenuapai at full capacity. It also reflects those who still are stuck in the past and think that because, for example we did things a certain way with Hercs and Andovers, or with Orions, that is the way it is done and anything else is rubbish.
The interesting point about the B777-200ER in freight mode is that it can lift a 100 tonne payload, so whilst it wouldn't be able to lift that down to the ice, it would still be able to lift a significant load to the ice. That is an advantage in itself.
