doors in general you won t open a door into the fire or into that fuel, but i will say that some of the challenges for folks that can t see things and if this fire developed and smoke developed, circumstances may have changed. you want to get the passengers off on the side that s the safest but perhaps they couldn t see what they couldn t see at the time before it developed, but the good news is, the evacuation worked. you had good crew resource management with other pilots conveying information about the leaking fluids coming out of the engine and so all of this is really important. this is a success. no one was killed. you re absolutely right. it could have been a lot worse. debra hersman, former ntsb chair. thanks very much. let s bring in our aviation analyst miles o bryan and the former ntsb managing director peter goals. do 767s have a good safety record, aad safety record?
