The maiden flight of the world’s largest airship has been postponed. The 92-meter-long Airlander 10 hybrid airship was due to take off for test flights north of London.

But its developer Hybrid Air Vehicles canceled the flight because of a “technical issue.” The company has yet to specify when the flights will resume.

The giant aircraft is a combination of blimp and plane, which allows it to carry a higher load while consuming less fuel. Its maker says it can fly at up to nearly 150 kilometers per hour and stay airborne for 2 weeks. The project has cost 30 million pounds.
