Boeing 747-100

Four engines, a hump above the cockpit and behind it just three small windows: that is what the jumbo looked like when it changed aviation. The Boeing 747-100 is the first production version of the 747 and the first widebody jet to carry passengers in scheduled service. From 1970, it made long-distance travel affordable for a mass audience. Here you will learn how the program came about, why Boeing built a factory of its own for it, how to tell the 747-100 from its successors and where you can still see the original jumbo up close today.

What is the Boeing 747-100?

The 747-100 is the beginning of a family that was built for over half a century. The type was a gamble: in the mid-1960s, air traffic was growing rapidly, airports were congested, and airlines were looking for an aircraft that could carry significantly more passengers per departure than the then-common Boeing 707. Boeing answered with a widebody aircraft with two aisles in the cabin – the first of its kind in scheduled service.

The impetus came from Pan Am. In April 1966, the US airline ordered 25 aircraft for a total of 525 million US dollars and thus became the launch customer. After further orders came in, including from Japan Airlines and Lufthansa, Boeing gave the go-ahead for production in July 1966.

In a typical seating layout, the base version offered around 366 seats, flew at Mach 0.84 and covered around 8,500 to 9,800 kilometers depending on version. It was flown by three people: two pilots and a flight engineer. Power came from four Pratt & Whitney JT9Ds – large high-bypass turbofans of a new generation, without which an aircraft of this size could not have been operated economically. You can find more about the engine maker on the Pratt & Whitney page.

Everett: a factory for a new aircraft

For an aircraft of this size, Boeing simply had no suitable hall. In June 1966, the manufacturer therefore bought a site of around 320 hectares near Everett, north of Seattle, right next to Paine Field airfield. Before anything could even be built, huge amounts of earth had to be moved to level the hilly terrain.

The hall went into operation in 1967 and, after several expansions, is today the largest building in the world by volume according to Guinness World Records. For decades, all 747s rolled off the line here, later joined by the 767, 777 and, for a time, the 787. The last 747, a freighter for Atlas Air, was delivered in early 2023. If you travel to Everett today, you can take a closer look at the plant site through the offerings at Boeing Future of Flight in Everett and watch test flights from Paine Field.

From rollout to the first scheduled flight

On September 30, 1968, the prototype with the registration N7470 rolled out of the hall in Everett. A good four months later, on February 9, 1969, it took off for its first flight. In the cockpit sat test pilots Jack Waddell and Brien Wygle and flight engineer Jess Wallick. An extensive test program followed, ending in certification by the US Federal Aviation Administration (FAA) in December 1969.

After that, things moved quickly. On January 15, 1970, the then First Lady Pat Nixon christened a Pan Am aircraft in Washington with the name Clipper Young America. The first scheduled flight was set for the evening of January 21, 1970, from New York JFK Airport to London Heathrow. But an engine on the christened aircraft overheated. Pan Am swapped the aircraft for the Clipper Victor (N736PA), and the jumbo took off several hours late – arriving in London on January 22.

The Clipper Victor later made history in a tragic way: it was destroyed on the ground at Tenerife in 1977 in the collision of two jumbos, the deadliest accident in civil aviation to this day – more in the article The 1977 Tenerife air disaster. You can find the detailed history of the family in the article The history of the Boeing 747.

The versions of the 747-100

At 205 aircraft, the 747-100 remained a comparatively small production run. As early as 1971, the heavier 747-200 arrived with more powerful engines and longer range, which quickly became the standard. Nevertheless, three versions of the -100 were built:

Version	Use	Special feature	Built
747-100	Long-haul, passengers	Original version, initially three upper deck windows per side	167
747-100B	Long-haul, passengers	higher takeoff weight, one aircraft for Iran Air, eight for Saudia	9
747-100SR	Short-haul in Japan	reinforced structure for many takeoffs, up to around 550 seats	29

The 747-100B was a latecomer: one aircraft went to Iran Air, the other eight to Saudia, which ordered its jets with Rolls-Royce RB211 engines. The 747SR (Short Range) was developed by Boeing for Japanese airlines that wanted to carry as many people as possible per departure on heavily traveled domestic routes. With tight seat pitch, around 500 to 550 passengers fit in, depending on version. The short-haul version 747-400D later took on a similar role.

Besides the passenger versions, quite a few 747-100s were converted to freighters after their time in scheduled service. Two aircraft from American Airlines and Japan Airlines also ended up with NASA and, as Shuttle Carrier Aircraft, carried the space shuttles piggyback across the US.

How to recognize the 747-100

The silhouette tells you right away that it is a jumbo. The harder question is exactly which 747 it is – especially on old slides, archive photos or in a museum. These features help you:

747-100 or 747-200?

That is the real puzzle, because from the outside the two are nearly identical. The -200 has a higher takeoff weight, more fuel and more powerful engines – you can see little of that on the fuselage. Three upper deck windows are a good clue for the -100, but not in every case: Boeing later offered an upper deck with ten windows per side, and some early aircraft were converted afterward. Only registration and serial number bring certainty. With them you can find the exact version and customer code in production lists, such as 747-121 for Pan Am or 747-128 for Air France. How registrations are structured is explained in the article Understanding aircraft registrations.

You can find a compact overview of all variants from the -100 to the -8 in the article Telling the Boeing 747-100 through 747-8 apart. And if you want to compare the jumbo and the superjumbo, see the guide Telling the A380 and Boeing 747 apart.

The role of the 747-100 in mass aviation

The 747 doubled at a stroke the number of seats an airline could offer on a long-haul route. More seats per flight meant lower costs per passenger – and thus room for cheaper tickets. Long-distance trips that had previously been reserved for a small, wealthy class became affordable for considerably more people in the 1970s. The jumbo is therefore regarded as the aircraft that made mass tourism on long-haul routes possible in the first place.

The start was not easy all the same. The 747 arrived at a time of weakening demand and rising oil prices, and many airlines initially could not fill their huge cabins. Some converted parts of the cabin into lounges or bars to use the space attractively. Competition grew too: with the Lockheed L-1011 TriStar and the McDonnell Douglas DC-10, smaller widebody jets came onto the market, and with the Concorde, a supersonic future seemed within reach. In the long run, though, the concept of “many seats, low price” prevailed – and with it the jumbo.

Major airlines shaped their image with the 747. Japan Airlines became the largest 747 operator of all time, and Pan Am, Air France, British Airways and Northwest made the jumbo the symbol of their long-haul operations. Many of the liveries of the time are cult today – some of them are shown in the article Legendary airline liveries of history.

Where to see the 747-100 today

As of October 2026, the 747-100 no longer flies in civilian scheduled service. If you want to experience the original jumbo, plan a museum visit. The most important preserved examples:

Registration	Version	Location
N7470	747-121, prototype	Museum of Flight Seattle
N747GE	747-121	Pima Air & Space Museum Tucson
N481EV	747-132 (freighter conversion)	Evergreen Aviation & Space Museum
N905NA	747-123, NASA shuttle carrier	Johnson Space Center, Houston
F-BPVJ	747-128 (Air France)	Musée de l’Air et de l’Espace Le Bourget

Fuselage sections come on top: the National Air and Space Museum in Washington shows the nose of the former Northwest aircraft N601US, and the nose of the British Airways aircraft G-AWNG is at the Hiller Aviation Museum in California.

The prototype N7470 in Seattle

The most important example is the prototype itself. After the certification flights, Boeing used N7470 for many more years as a test bed, including for new engines from other Boeing programs such as the PW4000 of the 777. In 1995, Boeing officially handed the aircraft over to the Museum of Flight, where it was extensively restored in 2013 and 2014. Today it stands in the Aviation Pavilion – in its flight test configuration. A visit combines well with spotting at the neighboring airfield: you will find information on that at the spot Museum of Flight at Boeing Field.

In Germany and Europe

In Europe, the Air France aircraft F-BPVJ at Le Bourget is the first address for a real 747-100. In Germany, you get closest to the original jumbo at the Technik Museum Speyer: there stands the Lufthansa 747 D-ABYM, a 747-230 – the direct successor version with almost identical looks. Further destinations for a day trip are collected in the article Aviation museums in Germany.

Photo tips for museum jumbos

• Plan for distance. At around 70 meters long and almost 60 meters of wingspan, a 747 rarely fits completely in the frame inside a hall. A wide-angle lens or a panorama from several shots helps.
• Details instead of the full view. If the whole aircraft does not fit in the photo, concentrate on the features: three upper deck windows, the JT9D nacelles, the landing gear with its four main gear legs.
• Document the registration. With museum aircraft, a photo of the registration or the information board is worthwhile. That way you can assign the version cleanly later.
• Outdoors in good light. Aircraft displayed outdoors, such as in Tucson or Le Bourget, look best at a low sun position. When the sun is favorable is shown in the guide to the sun position at your photo spot.
• Classify archive pictures. If you are identifying old slides or photos from the family archive, you will find more help in the article Recognizing vintage aircraft in the sky.

Why the 747-100 disappeared so early

The 747-100 was a pioneer – and pioneers are quickly overtaken. The first JT9D engines had teething troubles, and takeoff weight and range were limited. With the 747-200, Boeing had a version on offer shortly after market launch that provided more fuel, more payload and more range. From then on, airlines ordered almost only the -200, later the -300 and, from 1989, the 747-400 with a glass cockpit and a two-person crew.

When more efficient twinjets took over long-haul routes, the old Classic jumbos with three crew in the cockpit and high fuel burn were hardly economical anymore. Many 747-100s kept flying as freighters after their passenger careers before they were finally retired. What remains is the legacy: without the 747-100, there would be neither the later jumbo versions nor the factory in Everett, where widebody jets are still built today. How the jumbo ranks among the giants of aviation is shown in the article The largest aircraft in the world.

Conclusion

The Boeing 747-100 is the jumbo with which it all began: ordered by Pan Am in 1966, in the air for the first time in 1969, in scheduled service across the Atlantic in 1970. It made long-haul flights affordable for the masses and gave Boeing a plant that still holds records today. You will not see it in operation anymore, but preserved examples stand in Seattle, Tucson, McMinnville, Houston and Le Bourget – above all the prototype N7470.
