The Telegraph reports on the possible come-back of airships, the lighter-than-air aircrafts that 70 years ago were meant to sail noiselessly across the Atlantic like aeronautical cruise ships.
A group of British engineers from Hybrid Air Vehicles has built a scale prototype of what will soon be the largest flying vessel in the world -- a huge balloon made of ultra-lightweight, super-strong polyester on top of a hovercraft landing system. If it works, it could change the future of flight. The prototype will be a 300ft-long surveillance vehicle capable of staying airborne for 21 days at a time for the US Department of Defence.
"It's not an 'airship'," says, the company's marketing man Gordon Taylor. "It's a 'hybrid air vehicle'."
