The Berlin Airlift: Reading a Blockade as a Test of Will
It is June 1948. The Soviet Union has blocked all land and rail access to West Berlin, a Western-held enclave 100 miles inside the Soviet zone. The city's 2.2 million residents need roughly 4,500 tons of supplies daily (food, coal, medicine) to survive. The Western powers can fly cargo planes in through three air corridors. Each plane carries about 10 tons; a round trip takes several hours, and the fleet can sustain roughly 300 sorties a day. Winter will raise coal demand. The Western allies must decide whether to attempt resupply by air, abandon the city, or force a ground convoy through the blockade. Abandoning Berlin would be a visible retreat; forcing a convoy risks war.
1. Using the tonnage and sortie figures, assess whether an airlift can meet the city's needs, and identify the key variable that determines feasibility.

Capacity check:
- 300 sorties/day × 10 tons = 3,000 tons/day against a need of 4,500 tons/day.
- That is a shortfall of 1,500 tons/day - roughly two-thirds of requirement at these figures.
On the stated numbers, a sustained airlift cannot fully meet demand. So the choice is not simply "airlift or not" - it is whether the shortfall can be closed.
The key variable is sortie rate and load, not the blockade itself. Feasibility hinges on:
- Raising sorties (more crews, more planes, round-the-clock operations);
- Larger loads per aircraft;
- Rationing to cut demand, especially before winter coal needs spike.
The judgment: the airlift is marginal at 300 sorties but becomes viable if capacity is pushed up and demand managed. The exam rewards recognizing that the decision turned on logistics arithmetic and its elasticity, not on political rhetoric alone.
2. The allies ultimately chose the airlift over abandoning Berlin or forcing a convoy. Justify that choice using the strategic logic of the setup, and explain why 'forcing a convoy' was the weakest option.

Why airlift beat the alternatives:
- Abandoning Berlin = visible Western retreat, ceding the city and undermining credibility with Western Europe. It concedes the political contest without a fight.
- Forcing a convoy = the blockade is a military tripwire. Running ground transport through Soviet-controlled territory invites direct confrontation and risks war over supply trucks - disproportionate stakes for the objective.
- Airlift = a calibrated response: it contests the blockade below the threshold of war, signals resolve, and - crucially - is reversible and deniable if tensions ease. It converts a military standoff into a logistical and moral contest the West can win publicly.
The weakness of the convoy option is escalation asymmetry: it matches the Soviets at their strongest point (ground control) rather than at a point of Western advantage (air capability and industrial capacity).
The exam point: Cold War crises were managed by choosing the arena of confrontation - answering a ground blockade in the air kept the contest from becoming a war while still refusing to concede.
