The Airlander 10, the world's largest aircraft, took to the skies for the first time over Bedfordshire, England, on Wednesday and completed a lap of Cardington airfield before safely landing, the BBC reports.
At 92 metres (300 feet) in length, the helium-filled airship is 19 metres longer than the Airbus A380, the world's largest passenger jet.
The Airlander 10 has been nicknamed "The Flying Bum" due to its peachy behind's striking similarity to the human rump.
While the airship was originally in production in the US for surveillance purposes, Defense department budget cuts meant the project was abandoned. UK company Hybrid Air Vehicles stepped in and brought it to Britain.
It is designed to stay aloft for up to five days and will cost £25 million (around $33 million or AU$43 million). HAV says it could be used to deliver aid.
