Doctors believe food poisoning or a flu virus caused an Alaska Airlines pilot to pass out on a Seattle-bound flight that was diverted to Portland 
Thursday night, an airline spokeswoman said.
Alaska Airlines Flight 473 from Los Angeles to Seattle landed in Portland Thursday night after the pilot passed out. The copilot landed the Boeing 737 safely at Portland International Airport shortly after 9 p.m. and the pilot was taken to the hospital, officials said.
No one was injured.
If the president of the newly formed Jet Airways pilots’ union is to be believed, the reason for some 400 of its members falling "sick" Tuesday, perhaps, was food poisoning.
"We are not on strike. This is an individual decision by each pilot," said Girish Kaushik, president of the National Aviators Guild, after member pilots reported sick and inconvenienced some 20,
Asked if it was not too much of a coincidence that so many pilots reported sick at the same time, Kaushik told IANS,
"We could all have had food poisoning. That’s why we all could have become ill."
The civil aviation ministry has taken strong exception to what it calls a "wildcat" strike.
