Turkey's national carrier moved all its planes and operations from Istanbul's old airport to its shiny new one in an intense 41 hours over the weekend.

Turkish Airlines moved thousands of pieces of equipment - including planes, aircraft-towing vehicles, and security sensors - from its base in Atatürk Airport to New Istanbul Airport over 41 hours on Friday and Saturday.

The airline started the process, which it dubbed the "Great Move," at 3 a.m. Friday and completed it at 8 p.m. on Saturday, Turkish Airlines confirmed to Business Insider in a statement.

Hundreds of trucks carried more than 10,000 pieces of equipment, weighing about 44 tons, Turkey's Daily Sabah newspaper reported. The two airports are about 20 miles apart.

Mehmet Turhan, Turkey's transport minister, called it "the biggest move in world aviation history" in a TV broadcast cited by the Daily Sabah newspaper. The Guardian and Financial Times (FT) referred to the operation as "the big bang."

İlker Aycı, the chairman of Turkish Airlines, said in a Saturday statement: "Successfully concluding its mission of being the home of our brand throughout our 86 years of history, saying farewell to Atatürk Airport was a highly saddening experience for us."

Aycı added to the FT that the first 12 hours of the process was "very stressful" but "there was no crash, no loss and no big or small crisis."

The $11 billion project is a pet project of Turkish President Recep Tayyip Erdoğan's. Turkish Airlines described Erdoğan as "the originator behind the idea of this monumental project and its biggest supporter" in its Saturday statement.

Authorities hope the airport will accommodate 90 million passengers a year, which would be an increase of nearly 50% on the 64 million passengers Atatürk Airport reported in 2017.

Aycı, the Turkish Airlines chairman, and Turhan, the transport minister, on the weekend described the airport as the "biggest airport project of the world."

The opening of the airport had been delayed multiple times. Cranes could still seen near the terminal building on Saturday, the FT reported.
