HubertH,
sorry to disappoint you, but nothing "confirmed by Polish offcials" in yesterday's article you are quoting. Just some press rumors, like many, many others, this time even without any precise final conclusion. As for now, the 10:56 time, even if wrong, still offcially remains.
There were many other, earlier rumors about the time of the crash, but again, only rumors.
Sergei's information is precise and based on hard facts. Quite a difference here.
