<It will be interesting to see the outcome of the inquiry into this accident.>
I shouldn't be difficult to quickly assay the engines, for fuel, ash or compressor damage. If it's a fuel problem things will get very quite over there. If it's an ash problem, the phones will start ringing in all the international airline ops sections within hours.
If it's a weather problem, Boeing will be on this big time putting out reminders/restrictions with Airbus following suit.
