It may not count as a major Ozzie contribution to world aviation but the Victa Airtourer deserves a mention for it's longevity in production. In it's latest incarnation a couple have been sold by Pacific Aerospace to the Singapore Government for $NZ300,000 each. Considering it first entered production in 1961 that's not bad going.
