How about we stop this Ryan-bashing and look at the scenario. You are the crew. ATC report smoke coming from the engine after landing. One thing is for sure, they are not going to let you park that thing on one of their nice airbridges and risk smoke getting into the terminal. Now what do you do? Allow the passengers to remain aboard, with the possibility that the whole thing may go up on you? Or do what this crew did, evacuate the passengers and leave the airport fire services, who have bigger extinguishers than you, tackle the problem. No, I wasn't there, and can't say for sure that they made the right decision, but something tells me that I would have done the same thing. Nobody hurt and the aircraft intact. Fly with you anytime, Captain.
