We fly with two pilots at all times. We have a crew of up to 20 people, which includes extra pilots, engineers, mechanics and ground crew. We only need a hangar about twice a year, for maintenance checks. Normally, the ship is kept outside, day and night, on tour all over the country for 10 months of the year. Due to strong, lightweight materials for envelopes and gondolas developed since the 1970's, virtually all airships today are non-rigid.
All airships are dirigeables.
Our airships could stay aloft, without refueling, for up to 24 hours. With extra tanks, one of our Skyships flew for 52 hours without refueling in 1990. Our airships normally operate at around 1,500 to 3,000 feet. We can, however, go up to 8,000 but the payload is reduced. Inc. All Rights Reserved.
