I get a fire warning shortly after takeoff and i'm headed back for a landing too!
A fire WARNING is not the same as FIRE. Smoke detectors are not perfect and they can trigger without actual smoke. I've had smoke detectors go off from condensation by livestock and fruits. Your sensitive nose will tell you right away if it's smoke from fire, smouldering electrics or chemical reaction, or air conditioning oily smoke from a faulty pack. For example, when I'm in my seat on the upper deck, I can tell instantly if someone downstairs were to light up a cigarette by the way the air is circulated. So, in reference to this cabin incident, if you don't
SMELL smoke, it's practical reality to first investigate the area of the activated smoke detector before making snap decisions to land and to evacuate.
