Air France 447 - AFR447 - A detailed meteorological analysis - Satellite and weather data
This study was significantly updated on June 1, 2011 in memory of the 2nd anniversary of the crash. Also it was precipitated by the renewed interest in the fate of the flight with the data recorders having been recovered a few weeks ago. Interestingly it appears that almost all of the conclusions in my earlier study were correct. The purpose of this update is to introduce some new information, make corrections where necessary, edit extraneous theories that can now be disregarded, and clean up the text a bit.
