''I was in the right place at the right time, and just happened to have my Nikon in the boot so I got a few shots in the rain.''
It was low and loud enough to shake nearby houses, he said.
A reader posting on the Advocate's Facebook page, Debe Anderson, said she was at a friend's home next to the airport when the monster plane roared overhead.
''I really thought we were going to die as it sounded so loud. I thought it was the Air New Zealand plane off course and about to crash in their yard ... Then I looked out the window to see this huge beast flying past.''
The Boeing C-17 Globemaster III is a military transport aircraft developed for the US Air Force. The first production model flew in 1993. It is 53m long, has a wingspan of 52m and a maximum takeoff weight of 265,350kg. It can carry a tank, six armoured vehicles or 134 soldiers.
Australia agreed to buy four Globemasters in 2006 for US$780m ($940m). It currently has six.
By comparison the C-130 Hercules operated by the Royal New Zealand Air Force has been in service since the 1950s and is 30m long with a 40m wingspan and maximum takeoff weight of 70,300kg.
An RAAF spokesman told reader Andrew Simonsen, whose spectacular video can be seen on our Facebook page, that the kind of terrain New Zealand offered in places like Queenstown and Whangarei couldn't be replicated in Australia.
''So the crews really appreciate this chance to come over,'' he said.
The plane was in New Zealand for routine training and returned to Australia on Thursday.
If it had landed at Onerahi taking off would have been interesting. When fully laden it needs a 2.3km runway to get airborne.
