> a firefighting truck was responding to a separate incident on a flight that had aborted its takeoff and reported a strange odour on board. Air traffic control recordings suggested the odour on the plane had made some flight attendants feel ill.

Not making light of this, but I imagine there is another story of the person who had some strange scented product that led the flight attendants to play it safe and phone it in. There may very be someone whose strong cologne or forgetfulness to leave a chemical at home resulted in 2 deaths :(
