Its not like anyone died, there was no smoke or fire or anything that could leave a lasting imprint on someone. Sure it would be stressful, for about 10mins (the flight would have been only 3 or 4 mins long) but is that enough to cause long term damage? If so, eat a bag of cement and harden up.
Right. It was nothing at all. Nothing that would keep a professional from sleeping right for over a month afterward, like Capt. Sullenberger or Doreen Welsh
People almost died. Some will have very long lasting effects. Some won't. It isn't their fault if they do.
The fact that the event was over relatively quickly doesn't change the fact that they suffered from trauma. Some did not suffer much. Some suffered greatly.
