First, my CONGRATULATIONS to Asiana214 cabin crew, they not only did an excellent job, the did the perfect evacuation by the book, 90 secīs = everybody out. No questions on that.
Second, what happened we will see and learn from it, Iīm the first one interested, but still nobody knows the chain of errors that lead to the crash. As a LTC I always have 3 extra set of eyes in my head looking around in and out, and another 3 extra set of ears for weird noises, my mind is already 15min ahead of the flight and my hands and feet are fully ready to take control if needed. Itīs not nuclear physics....
