No euphemism, simply a statement of the findings that are supported by the evidence to date.
"The damage observed in the forward section of the aircraft appears to indicate that the aircraft was penetrated by a large number of high-energy objects from outside the aircraft"
With the usual caveats that accompany a preliminary report including, in this case, the statement that further work will include (among other things)
"forensic examination of wreckage if recovered and possible foreign objects, if found"
