Only caught a brief segment of the press conference live... but they had a computer simulation showing what happened.
Curiously enough the simulation stops as the front gear leaves the runway and the investigator said something to the effect of "this is where the flight recorders stopped due to the shock of leaving the runway".
I call BS on this one... these things are designed to 3,600 G's of force and they "stopped working" at the end of the runway.
Makes me wonder if Canada lacking the equipment and budget to examine the recorders themselves handed it over to Airbus for analysis and Airbus "truncated" the data to prevent the release of anything that may play them in an unfavourable light (as is speculated in the AF 296 flight in 1988)?
