evacuation was ordered from the flight deck, according to media reports of pax accounts. In the absence of more credible sources, this seems likely. No need to second-guess if it should or should not have been ordered, as long as we obviously know close to nothing, and don't know what the crew knew. Four people were lightly bruised, and got medical help on site. I see nothing highly unusual, and all I assume at this time is - job well done, by the pilots, cabin crew, emergency services and atc.
