Eighty four Cessna 180/185 aircraft attended the Weekend fly-in at Omaka to celebrate the 70th anniversary of the first flight of the prototype Cessna 180 N41697 c/n 604 on 26th May 1952.
The photograph below was taken by Agairnz on Sunday afternoon which shows ZK-CBS at the bottom of the shot taxiyng out for its demonstration.
There are only 83 180/185's in this line up as ZK-CBF attended on the Saturday only.
Off the top of my head I cannot tell you which Cessna 180 first flew in NZ but ZK-BDB, ZK-BDC, ZK-BDD, ZK-BDE, ZK-BDF and ZK-BDU were all registered here on the 11-08-1953.
Of this batch ZK-BDB c/n 30462, ZK-BDD c/n 30463 and ZK-BDE c/n 30459 are still current.
The earliest production Cessna 180 in NZ is ZK-WGT with c/n 30012 which was registered here on 05-01-2007; with ZK-BKG c/n 30376 the next numerically; which joined our register on 05-10-1955.
