				 The 
				92-metre Airlander 10 floated in a hangar in Cardington, central 
				England, at a media event where its backers showcased a vessel 
				they said could stay airborne for up to two weeks. 
				 
				Hybrid Air Vehicles is hoping the slow-moving, helium-filled 
				Airlander 10 will catch the eye of potential customers who might 
				want to use it to carry cargo or deliver aid, for surveillance, 
				communications or leisure purposes. It can carry 48 passengers. 
				 
				The Airlander can take off and land vertically meaning it does 
				not need a tarmac runway. It can also operate from open fields, 
				deserts, ice or water, meaning it could be useful for 
				humanitarian missions or coastguard monitoring. 
				 
				Airships have a long history stretching back to the nineteenth 
				century, although their use was curtailed by competition from 
				aeroplanes in the twentieth century and high-profile accidents 
				such as the Hindenburg disaster in 1937. 
				 
				Hybrid Air Vehicles is a privately-held firm funded so far by 
				17.5 million pounds ($25.2 million) raised from 1,000 
				shareholders, and which has benefited from U.S. investment and 
				British and EU grants. 
				 
				It will undertake additional ground testing before a first 
				flight in the coming months. 
				 
				The airship could then become a familiar sight over the central 
				English countryside as it aims to complete 200 hours of test 
				flights before demonstrations to would-be customers. 
				 
				Hybrid Air Vehicles hopes to be building 12 of the airships a 
				year by 2018.
