USS Akron (ZRS-4) was a helium-filled rigid airship of the United States Navy that was lost in a weather-related accident off the New Jersey coast early on 4 April 1933, killing 73 of the 76 crew and passengers on board.
During its accident-prone 18-month term of service, she also served as a flying aircraft carrier for launching F9C Sparrowhawk biplane fighters.
At 785 ft (239 m) long, 20 ft (6.1 m) shorter than the German commercial airship Hindenburg, Akron and her sister Macon were among the largest flying objects in the world. Although the Hindenburg was longer, it was filled with hydrogen, so the two U.S. airships still hold the world record for helium-filled airships.Source: YouTube
