The Berlin Airlift 1948/49: Candy Bombers, logistics and airports

Over West Berlin there is an almost constant drone. Every few minutes a silver four-engine aircraft appears over the rooftops of Neukölln, touches down at Tempelhof, is unloaded and half an hour later is back in the air. What began as an emergency measure in the summer of 1948 became the largest supply operation by air the world had seen until then. The Berlin Airlift is a piece of world politics – but above all it is a lesson in air transport logistics. This article explains how the system worked, which aircraft and airports were involved and where you can still find its traces in Berlin and elsewhere today.

The Airlift at a glance

From June 24, 1948, to May 12, 1949, the Soviet Union blocked all roads, railway lines and waterways between the western occupation zones and the western sectors of Berlin. Around two million people were thereby cut off from resupply. The US and Britain responded with an airlift: through the three air corridors the victorious powers had agreed in 1945, they flew in coal, food and everything else a major city needs. The first aircraft landed on June 26, 1948, and the last official landing followed on September 30, 1949 – more than four months after the end of the blockade, because the Allies were building up stocks in case of a renewed closure.

Why the blockade came about

After the Second World War, Germany was divided into four occupation zones, with Berlin as an island in the middle of the Soviet zone, divided into four sectors. Tensions between the Western powers and the Soviet Union grew, and the dispute came to a head over the currency. When the Western Allies introduced the Deutsche Mark in their zones in June 1948 and it was soon to apply in the western sectors of Berlin as well, the Soviet side closed the access routes.

There had already been a foretaste in April 1948: after interference with land traffic, the Americans supplied their garrison from the air for a short time, the so-called “Little Airlift.” That was a garrison supply. Supplying an entire city from the air was considered impossible by many in June 1948. The decisive point: the land routes were nowhere guaranteed by treaty, the air corridors were. Anyone blocking them would have had to shoot at aircraft.

The logistics: an assembly line in the air

The need was enormous. Before the blockade, in summer an average of a good 10,000 tons of goods per day came into the western sectors. As the minimum for survival, the planners estimated about 4,500 tons daily in summer and significantly more in winter, when heating was needed. In July 1948 the Airlift managed only around 2,000 tons per day at first. That the figure ended up far higher is mainly thanks to an organizational achievement.

Three corridors as one-way streets

The three air corridors were each about 32 kilometers wide and connected Berlin with Hamburg in the northwest, Bückeburg in the west and Frankfurt am Main in the southwest. For the Airlift they were used as one-way streets: in via the northern and southern corridors, out via the middle one. That way loaded and empty aircraft never met on the same route.

Within the corridors the aircraft flew at several altitude bands staggered 500 feet apart, and one behind the other at fixed time intervals. In the end a rhythm emerged in which, at peak times, an aircraft landed in Berlin every few minutes.

One attempt per flight

The fine-tuning came from Major General William H. Tunner, who in the Second World War had organized the supply flights over the Himalayas (“the Hump”) between India and China. In July 1948 he took over the American Airlift, later the joint American-British operational command based in Wiesbaden.

How necessary that was became clear on August 13, 1948, later called “Black Friday.” In bad weather the approaches backed up over Tempelhof, several accidents happened on the runway, and dozens of aircraft circled in holding patterns over the city. Tunner drew hard conclusions from it:

• No more circling: Anyone who missed their approach did not land on a second attempt but flew back west still loaded and rejoined the queue.
• Instrument flying as standard: Flights were made under instrument flight rules regardless of weather, so the rhythm did not depend on the sky.
• Fixed spacing: Landings followed at fixed intervals of a few minutes.
• Fast ground times: The crews stayed with the aircraft, snack carts came to the aircraft, and the time on the ground fell, according to German-language accounts, from around 75 to about 30 minutes.

All-weather operation was made possible by radar-guided approaches (Ground Controlled Approach). A controller on the ground guided the pilots by radio using his radar picture until just short of the threshold. For the time that was a big step; more in the overview of the history of air traffic control – and a reason why the Airlift is considered the birth of modern traffic flow management. Anyone who watches the approach chain at a hub today sees the principle again on a large scale; the guide Understanding hub waves is about this timing in modern scheduled traffic.

The Easter Parade

How capable the system had become by then was demonstrated by Tunner at Easter 1949. From noon on April 15 to noon on April 16, almost 1,400 aircraft landed in Berlin with just under 13,000 tons of cargo – mostly coal. The exact figures differ slightly depending on the source, the record is undisputed. After the Easter Parade the daily average performance stayed permanently higher than before.

The aircraft of the Airlift

For spotters the Airlift is above all a type parade of the late piston-engine era. German aircraft were not used, but German mechanics and workers certainly were.

Type	Operator	Role in the Airlift	Special feature
Douglas C-47 Skytrain / Dakota	USA, Britain	shaped the first weeks	twin-engine, around 3 tons payload, soon replaced by the C-54 for the Americans
Douglas C-54 Skymaster	USA	backbone of the American Airlift	four-engine, around 9 tons payload, several hundred aircraft in service
Avro York	Britain	most important British transport	derived from the Lancaster bomber
Handley Page Hastings	Britain	from late 1948	then-new RAF transport
Short Sunderland	Britain	flying boat operation until winter	landed on the Havel, carried salt among other things
chartered civilian aircraft	British companies	additional capacity	wide range, e.g. Lancastrian, Bristol Freighter or converted Halifax

The C-54 Skymaster, the military version of the civilian DC-4, is the true Candy Bomber: it carried more than the C-47, was faster and could be used well in the rhythm. Everything important about the type is in the profile of the Douglas C-54 Skymaster and the civilian Douglas DC-4. You will find the twin-engine predecessor under Douglas DC-3 / C-47, and its history is told in the article Douglas DC-3: the aircraft that changed aviation.

The British had fewer large transports and therefore relied on variety. The Sunderland flying boats took off from the Elbe near Hamburg-Finkenwerder and landed on the Havel. Their hull was protected against corrosion from seawater, which is why they carried the aggressive salt, among other things. When the Havel and Wannsee froze over in winter, the flying boat chapter was over.

The airports: three in Berlin, many in the west

Tempelhof in the American sector

The airport in the south of the city was the heart of the American Airlift and took in most of the cargo. The approach led low over the surrounding apartment blocks, and the pictures of children on rubble heaps in front of landing aircraft almost all come from here. Tempelhof remained a commercial airport for a long time and was closed in 2008; the site is now a public park, the Tempelhofer Feld. The whole story is in the article Tempelhof Airport and in the profile Berlin Tempelhof Airport.

Gatow in the British sector

The airfield in the west of Berlin was the base of the Royal Air Force and recorded the most movements. Nearby, on the Havel, the flying boats landed on the water. Gatow remained a British military airfield until 1994. Today the site houses the Military History Museum Berlin-Gatow airfield, which you can plan well via the spot page Luftwaffe Museum at Gatow airfield.

Tegel in the French sector

Tempelhof and Gatow alone were not enough. So on August 5, 1948, construction of a new airfield began in the French sector at the Tegeler Forst. Because heavy equipment was lacking, much was built by hand, and thousands of Berliners worked on the construction site. On November 5, 1948, the first C-54 landed, and in early December the field was officially opened. The main runway was about 2.4 kilometers long and was then considered one of the longest in Europe. This makeshift field later became Berlin Tegel Airport, which handed scheduled operations over to BER in November 2020 – read about it in the article Tegel Airport.

The departure fields in the west

The Americans flew mainly from Rhein-Main near Frankfurt and from Wiesbaden-Erbenheim through the southern corridor. The British used fields in their zone, including Faßberg (a focus for coal), Wunstorf, Celle, Lübeck and Schleswig, plus Hamburg-Finkenwerder for the flying boats. Many of these fields are military airfields or used otherwise today; at Wunstorf, for example, the Luftwaffe (German Air Force) is stationed with the A400M, as the guide to Wunstorf air base shows. How to tell today’s transports apart is explained in the article Recognizing military transports. The Rhein-Main field is part of the history of today’s Frankfurt Airport.

Airfield	Sector/zone	Main role
Tempelhof	US sector of Berlin	destination airport with the largest cargo volume
Gatow	British sector of Berlin	destination airport with the most movements, flying boats on the Havel
Tegel	French sector of Berlin	additional destination airport from late 1948
Rhein-Main / Wiesbaden	US zone	departure bases for the southern corridor
Faßberg, Wunstorf, Celle, Lübeck, Schleswig	British zone	departure bases for the northern corridor

Halvorsen and the Candy Bombers

The best-known story of the Airlift is a small one. US pilot Gail Halvorsen (1920–2022) saw children at the fence at Tempelhof and promised them candy. So that they would recognize his aircraft in the stream of approaches, he wiggled his wings on approach – which earned him the nickname “Uncle Wiggly Wings.” Before landing, his crew dropped chocolate and chewing gum on small parachutes.

The private action became an operation of its own called “Little Vittles,” modeled on “Operation Vittles,” as the Americans called the Airlift. By the end, around 23 tons of candy are said to have been dropped. Halvorsen stayed connected to Berlin and was commander at Tempelhof in the 1970s.

Where exactly the term “Rosinenbomber” (“raisin bomber”) comes from has not been conclusively settled. It is usually linked to flights that brought dried fruit for Christmas baking in 1948. What is clear is that it came from Berliners’ everyday speech and that, only a few years after the end of the war, “bombers” had turned into supply aircraft – which is exactly what made the word so catchy.

The price of the Airlift

Continuous operation at one-minute intervals, in all weather and with exhausted crews, took its toll. At least 101 people died, most of them in flying accidents. Frequently cited are 31 Americans and about 40 Britons, plus German civilians, such as workers at the airfields. The exact figures differ depending on the source. Measured against flight hours, the accident rate was nevertheless lower than the planners had feared.

On top of that came harassment from the Soviet side: fighters flying close to transports, searchlights or anti-aircraft exercises near the corridors. No transport was shot down – the Airlift remained a logistical, not a military confrontation.

The end and what remained

After the blockade proved ineffective, the Soviet Union signaled willingness to talk in spring 1949. On May 12, 1949, shortly after midnight, trucks and trains rolled to West Berlin again. The flights continued to build up stocks and were gradually reduced until the official end on September 30, 1949.

Politically the Airlift had a great effect: in the perception of many Berliners, occupiers became protecting powers, and the experience shaped the relationship between the later Federal Republic and the Western powers. In aviation terms it showed what is possible with rhythm, standardization and radar guidance – ideas that became a matter of course in scheduled traffic in the following decades. The air corridors themselves remained the way into the city until 1990, and only airlines of the three Western powers were allowed to fly scheduled services to West Berlin, which shaped the city’s special transport history until the end of the Cold War. How things went on with Tegel and the Berlin airlines is shown in the articles on Air Berlin and – on the other side of the Wall – on Interflug.

Traces of the Airlift today

If you are interested in the Airlift, you can spend a whole day on it in Berlin.

Before you photograph the exhibits, it is worth a look at the guide Recognizing vintage aircraft in the sky. It helps you tell the C-47, DC-4 and other piston-engine classics apart by details such as engine nacelles, tail and landing gear. And if you want to see current jets between museum and memorial, you will find the right finish in the plane spotting guide for BER and at the BER observation deck.

What to keep in mind

• Read numbers carefully. Tonnages, flight counts and casualty figures differ depending on the source and method of counting, for example whether outbound and return flights are counted separately. Anyone who needs exact values should cite the source.
• Military is not the same as civil. The C-54 and DC-4 are closely related but not identical. With historic aircraft it pays to look at serial numbers; how US military serials are structured is explained in the article US military serials.
• Airworthy vintage aircraft are rare. Only a few aircraft from the Airlift era still fly. When one shows up at an air day, it is a highlight – better plan the sighting early.
• Respect memorial sites. The Airlift Memorial is also a place for the dead of the operation. Photos are of course fine there, climbing on the base is not.

Conclusion

For eleven months the Berlin Airlift was the lifeline of a major city. Its success rested less on individual heroic deeds than on a thoroughly organized system: one-way corridors, staggered altitudes, fixed landing intervals, radar approaches and short ground times. The C-54 Skymaster became its symbol, Tempelhof, Gatow and Tegel its stages, and the nickname “Raisin Bomber” still obscures that it was mainly coal that was flown. In Berlin you can walk its traces in a day – from the memorial across the Tempelhofer Feld to Gatow airfield.
