Taildragger, Rokape,
See comments by Pass-a-frozo, Capt Sand Dune, Buster etc.
This is a big aircraft, capable of landing on semi-prepared (dirt) strips, in areas where nasty people shoot at you.......
The total cost (because we have to explain the FULL amount, not hide costs like Qantas etc as described by Buster) includes spares for a certain number of years, initial crew training (and probably continuity training in a simulator - so we don't have to buy one), special GSE for that aircraft, probably some maintenance support etc.
In other words, we have to buy enough "stuff" to support the aircraft.
Don't get me wrong - they are expensive - but ask the Brits what they think of theirs. Initially they "leased" them (for an amount close to the cost of buying them I understand) but have now decided that the aircraft is so good they will buy them (and one other they hope) outright.
And Wessex - thats what you get for buying second hand. Mind you, they Kiwis seem to get theirs to work................
