I will be interested to understand the sequence of events which led to the failures observed.
As the MLG is quite far aft of the intake for the engines, although plausible, is it likely that a burst tyre, especially one on the rear axle, would eject debris far enough forward to be ingested?
I know that the engine intake danger areas extend around and aft of the intake itself, especially at high-power settings, and that forward speed of the a/c at the time of the tyre failure could influence this scenario, however, is it possible that the engine damage was caused by other debris, which in turn led to the ejection of shrapnel into the tyre causing it's subsequent failure?
