At the Airport

An airport scene
April 30, 2006, 7:00 A.M. I’m in an airport’s check-in hall, gripping my baggage cart while being jostled by a crowd of other people also checking in for that morning’s first flights. The scene is familiar: hundreds of travelers carrying suitcases, boxes, backpacks, and babies, forming parallel lines approaching a long counter, behind which stand uniformed airline employees at their computers. Other uniformed people are scattered among the crowd: pilots and stewardesses, baggage screeners, and two policemen swamped by the crowd and standing with nothing to do except to be visible. The screeners are X-raying luggage, airline employees tag the bags, and baggage handlers put the bags onto a conveyor belt carrying them off, hopefully to end up in the appropriate airplanes. Along the wall opposite the check-in counter are shops selling newspapers and fast food. Still other objects around me are the usual wall clocks, telephones, ATMs, escalators to the upper level, and of course airplanes on the runway visible through the terminal windows.
The airline clerks are moving their fingers over computer keyboards and looking at screens, punctuated by printing credit-card receipts at credit-card terminals. The crowd exhibits the usual mixture of good humor, patience, exasperation, respectful waiting on line, and greeting friends. When I reach the head of my line, I show a piece of paper (my flight itinerary) to someone I’ve never seen before and will probably never see again (a check-in clerk). She in turn hands me a piece of paper giving me permission to fly hundreds of miles to a place that I’ve never visited before, and whose inhabitants don’t know me but will nevertheless tolerate my arrival.
To travelers from the U.S., Europe, or Asia, the first feature that would strike them as distinctive about this otherwise familiar scene is that all the people in the hall except myself and a few other tourists are New Guineans. Other differences that would be noted by overseas travelers are that the national flag over the counter is the black, red, and gold flag of the nation of Papua New Guinea, displaying a bird of paradise and the constellation of the Southern Cross; the counter airline signs don’t say American Airlines or British Airways but Air Niugini; and the names of the flight destinations on the screens have an exotic ring: Wapenamanda, Goroka, Kikori, Kundiawa, and Wewak.
The airport at which I was checking in that morning was that of Port Moresby, capital of Papua New Guinea. To anyone with a sense of New Guinea’s history—including me, who first came to Papua New Guinea in 1964 when it was still administered by Australia—the scene was at once familiar, astonishing, and moving. I found myself mentally comparing the scene with the photographs taken by the first Australians to enter and “discover” New Guinea’s Highlands in 1931, teeming with a million New Guinea villagers still then using stone tools. In those photographs the Highlanders, who had been living for millennia in relative isolation with limited knowledge of an outside world, stare in horror at their first sight of Europeans (Plates 30, 31). I looked at the faces of those New Guinea passengers, counter clerks, and pilots at Port Moresby airport in 2006, and I saw in them the faces of the New Guineans photographed in 1931. The people standing around me in the airport were of course not the same individuals of the 1931 photographs, but their faces were similar, and some of them may have been their children and grandchildren.
The most obvious difference between that 2006 check-in scene etched in my memory, and the 1931 photographs of “first contact,” is that New Guinea Highlanders in 1931 were scantily clothed in grass skirts, net bags over their shoulders, and headdresses of bird feathers, but in 2006 they wore the standard international garb of shirts, trousers, skirts, shorts, and baseball caps. Within a generation or two, and within the individual lives of many people in that airport hall, New Guinea Highlanders learned to write, use computers, and fly airplanes. Some of the people in the hall might actually have been the first people in their tribe to have learned reading and writing. That generation gap was symbolized for me by the image of two New Guinea men in the airport crowd, the younger leading the older: the younger in a pilot’s uniform, explaining to me that he was taking the older one, his grandfather, for the old man’s first flight in an airplane; and the gray-haired grandfather looking almost as bewildered and overwhelmed as the people in the 1931 photos.
But an observer familiar with New Guinea history would have recognized bigger differences between the 1931 and 2006 scenes, beyond the fact that people wore grass skirts in 1931 and Western garb in 2006. New Guinea Highland societies in 1931 lacked not just manufactured clothing but also all modern technologies, from clocks, phones, and credit cards to computers, escalators, and airplanes. More fundamentally, the New Guinea Highlands of 1931 lacked writing, metal, money, schools, and centralized government. If we hadn’t actually had recent history to tell us the result, we might have wondered: could a society without writing really master it within a single generation?
An attentive observer familiar with New Guinea history would have noted still other features of the 2006 scene shared with other modern airport scenes but different from the 1931 Highland scenes captured in the photographs made by the first contact patrols. The 2006 scene contained a higher proportion of gray-haired old people, relatively fewer of whom survived in traditional Highland society. The airport crowd, while initially striking a Westerner without previous experience of New Guineans as “homogeneous”—all of them similar in their dark skins and coiled hair (Plates 1, 13, 2
6, 30, 31, 32)—was heterogeneous in other respects of their appearance: tall lowlanders from the south coast, with sparse beards and narrower faces; shorter, bearded, wide-faced Highlanders; and islanders and north coast lowlanders with somewhat Asian-like facial features. In 1931 it would have been utterly impossible to encounter Highlanders, south coast lowlanders, and north coast lowlanders together; any gathering of people in New Guinea would have been far more homogeneous than that 2006 airport crowd. A linguist listening to the crowd would have distinguished dozens of languages, falling into very different groups: tonal languages with words distinguished by pitch as in Chinese, Austronesian languages with relatively simple syllables and consonants, and non-tonal Papuan languages. In 1931 one could have encountered individual speakers of several different languages together, but never a gathering of speakers of dozens of languages. Two widespread languages, English and Tok Pisin (also known as Neo-Melanesian or Pidgin English), were the languages being used in 2006 at the check-in counter and also for many of the conversations among passengers, but in 1931 all conversations throughout the New Guinea Highlands were in local languages, each of them confined to a small area.
Another subtle difference between the 1931 and 2006 scenes was that the 2006 crowd included some New Guineans with an unfortunately common American body type: overweight people with “beer bellies” hanging over their belts. The photos of 75 years ago show not even a single overweight New Guinean: everybody was lean and muscular (Plate 30). If I could have interviewed the physicians of those airport passengers, then (to judge from modern New Guinea public health statistics) I would have been told of a growing number of cases of diabetes linked to being overweight, plus cases of hypertension, heart disease, stroke, and cancers unknown a generation ago.
Still another distinction of the 2006 crowd compared to the 1931 crowds was a feature that we take for granted in the modern world: most of the people crammed into that airport hall were strangers who had never seen each other before, but there was no fighting going on among them. That would have been unimaginable in 1931, when encounters with strangers were rare, dangerous, and likely to turn violent. Yes, there were those two policemen in the airport hall, supposedly to maintain order, but in fact the crowd maintained order by itself, merely because the passengers knew that none of those other strangers was about to attack them, and that they lived in a society with more policemen and soldiers on call in case a quarrel should get out of hand. In 1931 police and government authority didn’t exist. The passengers in the airport hall enjoyed the right to fly or travel by other means to Wapenamanda or elsewhere in Papua New Guinea without requiring permission. In the modern Western world we have come to take the freedom to travel for granted, but previously it was exceptional. In 1931 no New Guinean born in Goroka had ever visited Wapenamanda a mere 107 miles to the west; the idea of traveling from Goroka to Wapenamanda, without being killed as an unknown stranger within the first 10 miles from Goroka, would have been unthinkable. Yet I had just traveled 7,000 miles from Los Angeles to Port Moresby, a distance hundreds of times greater than the cumulative distance that any traditional New Guinea Highlander would have gone in the course of his or her lifetime from his or her birthplace.
