The maiden flight of the world's longest aircraft has been delayed because of a "technical issue".
The Airlander 10 - 302ft (92m) long and which cost £25m to build - was due to take off from Cardington Airfield in Bedfordshire on Sunday.
The aircraft can only fly during daylight hours during the test stage, and organisers feared the flight would not would not have been completed before dark by the time the issue was resolved.
It is not known when another attempt at a test flight will be made.
