How Blimps Work. by Craig Freudenrich, Ph.D. Airships are called lighter-than-air (LTA) craft because to generate lift, they use gases that are lighter than air. The most common gas in use today is helium, which has a lifting capacity of 0.064 lb/ft3 (1.02 kg/m3). Hydrogen was commonly used in the early days of airships because it was even lighter, with a lifting capacity of 0.070 lb/ft3 (1.1 kg/m3) and was easier and cheaper to acquire than helium.
