Think about how many passengers and crew have yet AGAIN been exposed to toxic chemicals and are now at risk of long term health problems. How many children and pregnant woman were on this flight?
as long as your thinking, why stop there.
Think about all the incidents in the past 50 years of flight that have involved toxic fumes of one sort or the other and think about all the crews and passengers aboard who have subsequently died that could be blamed on association with those fumes.
Data for the zealots is in the numbers, not the scientific proof .
