February 10 - Hybrid Air Vehicles (HAV) believes that its Airlander 10 airship - the world's largest aircraft - will be back in the air 'soon'.

HLPFI readers will recall that it suffered a 'heavy landing' in August last year during a UK test flight resulting in damage to the external structure of the cockpit.

HAV says that the Airlander 10 is designed to stay airborne for up to five days at a time manned, or more than two weeks if unmanned.

It makes little noise, creates little pollution and can take off from and land at small sites almost anywhere.
