Blimp disaster: Thanks to Jim Lushine, a retired weather service meteorologist, for passing along this interesting bit of history:
"Eighty years ago, on April 4, 1933, the greatest airship disaster in U.S. history occurred.
"No, not the hydrogen-filled Hindenburg, which burst into flames four years later, but rather the helium-filled USS Akron, a Navy airship.
"It had taken off from New Jersey, intending to fly off the East Coast, when it crashed in the ocean, killing 73 of the 76 aboard. According to survivors, the airship was hit by a violent storm.
"After reading accounts of the incident, I am convinced the airship was brought down by a strong down-burst of air, or what is today known as a microburst.
"This meteorological term coined, by Ted Fujita in the 1970s, has been linked to several major airline crashes.
"The most notorious of those: Delta Flight 191, which took off from Fort Lauderdale on Aug. 2, 1985, and crashed while attempting to land in Dallas, killing 137 souls.
"This and other incidents led to the deployment of Terminal Doppler Weather Radar. TDWR installations are located near the Fort Lauderdale-Hollywood and Palm Beach international airports, specifically to warn of potentially violent turbulence especially during landing."Copyright © 2015, South Florida
