Just getting there was just part of the fun day.
Nick F has sent in a heap of photographs from the day at Ohakea.
I will post the civil stuff and leave the military aircraft to the MRC Aviation and other blogs.
2 (c/n 26480/15035) does have a military past with the USAAF - but none with NZ. Its first dose of civil flying was in the Philippines, followed by time in Papua New Guinea and then moving down to Australia. It arrived in Auckland on 27-03-1987 for the Warbirds DC-3 Syndicate. It is now listed with Flight 2000 Ltd and painted to represent the RNZAF C-47 NZ3546.
Just being itself is this Papa51 Thunder Mustang ZK-TMG (c/n 018) from the Kiwi Thunder Group.
