A thread on RVSM contingency procedures ( nice input there Nitpicker) has a link to a website called Webtracker, I'd never seen it before, it's great. I looked up the approach in question to see how accurate the " missed out by seconds " quote was. It was pretty accurate! They got down to 1089 feet before climbing out. The interesting thing to me is that they commenced the miss at 1059:01 .
If they did maybe 700fpm for the last part of the approach that means they missed out by only about 20 seconds. Seems a bit crazy to me in that the go around would have made a lot more noise than continuing to land.
