It won't be the cheapest a/c to operate but the acquisition price will be very good given the current surplus of 75's in the market...certainly a very capable machine and well suited to this part of the world in terms of airfield and payload/range performance.
It's a pity our Govt didn't do the same thing assuming that the future tanker/transport replacement for the 707's will most likely be uesd 767-200ER's...think of the savings with pilots, engineers, support, spares, training etc...
Maybe we can do a swap?
