There is an excellent posting with graphs comparing the Asiana flight to a United 777 that landed 10 minutes before. The graphs compare height, speed and importantly energy. http://flyingprofessors.net/what-happened-to-asiana-airlines-flight-214-2/ http://flyingprofessors.net/what-happened-to-asiana-airlines... As most have hypothesized, it was an unstabilized approach and they should have done a go around (barring unknown technical/mechanical factors).

Looking at the graphs the plane was ahead of them by about 5-10 seconds. That usually doesn't turn out too well. Gotta be ahead of the plane, not the plane ahead of you. Usually a noob mistake (on the ground system failure, hard to fix) OR hopefully extensive extenuating circumstances (on the plane system failure, easy to fix).
