April-5 walk from Nanduo to Yunzain. This place was extremely poorly located, and, because of this, was closed by me on my first visit to the area in January 1959. "I immediately set about finding a more suitable site and chose Pindiu [Hube Census Division] for the purpose. There was in existence at that time a small grass strip at Pindiu. This was some 1,100 feet long, but could only be used by the Piper Cub aircraft of the Lutheran Mission. "I personally made several trips into the area, and, as a result, arranged for the Department of Civil Aviation to inspect and draw up plans for a more adequate airstrip. The survey was completed by 31 July 1959, and construction commenced immediately thereafter. "The first officer posted to Pindiu was Mr. P. J. K. Broadhurst. He was followed some short time later by Mr. P. G. Whitehead. The strip was opened in May 1960, and the first aircraft to go in was piloted by Laurie Crowley [now owner of Crowley Airways of Lae] with a District Airport Inspector and me as passengers. The airstrip has been extended slightly and the general condition considerably improved since it was originally opened. It is now classified as Category "C" and can take aircraft of the following types: most Cessnas, single or twin Otters, Piper Aztecs, Beech Barons and a number of others." One final commentary on this grassed airstrip is in order. During the first week of my stay at Pindiu we regularly heard an unidentifiable mechanical droning in the distance. The mystery was solved one day when we walked down to the strip to meet a scheduled flight. There was a gasoline lawn mower in full operation! We learned that mowing the airstrip was a cooperative venture on the part of several of the Pindiu men. Thus comes civilization to stone-age New Guinea!
