Aviation Hazards Aircraft operating near a tropical cyclone will be subjected to significant Low Level Wind Shear. Also, some aircraft cannot take off if the crosswinds over an airstrip exceed a certain value. In the overwhelming majority of cases, 35 knot winds (tropical gale wind envelope) exceeds this threshhold for military aircraft (Can’t take off, can’t launch helicopter for rescue operations). These turbulent conditions can become a very dangerous hazard to equipment and personnel safety.
DATELINE: October 31, 2000 -- Updated 06:14 p.m. EST, 2314 GMT (From CNN.com) Taiwan says 65 dead in Singapore Airlines crash Taiwanese officials say that at least 65 people died when Los Angles-bound Singapore Airlines Flight 006 crashed during takeoff in stormy weather in Taipei late Tuesday. James Boyd, an airline spokesman in Los Angeles, said that according to the latest information available from the crash site, 75 people on board the Boeing 747-400 were unaccounted for.
DATELINE: October 31, 2000 -- Updated 06:14 p.m. EST, 2314 GMT (From CNN.com) Taiwan says 65 dead in Singapore Airlines crash CNN Meteorologist Orelon Sydney reports the weather at the time of takeoff "was the equivalent of a Category 2 hurricane making landfall on the island. Shortly after the crash, bands of bad weather extending outward from Typhoon Xangsane were creating winds measured from 40 to 73 mph, Sydney said.
