Speculation at this point. If it's that, it might have ingested debris into one or more engines, or have been an attempted late aborted takeoff complicated by the high winds. One thing I noted earlier, prior to the accident, was the short amount of pavement needed to take off from 27L and the rapid rate of climb out of the airport amidst the strong winds.

I am not qualified in aerodynamics or piloting to make strong assertions here, though, so take that for what it's worth.
