As far as "stop that rubbish" is concerned, I will say this:
For all the Polish people who are seeking to apportion blame for this tragic accident:
1) It seems abundantly clear to me, and I suspect most 'professional pilots', that it was the Polish Air Force that killed everyone on board
2) It seems clear to me also that there may have been some sort of PAR in use, but it was only being used by ATC to 'monitor' the approach as is done in the UK sometimes. The a/c was not receiving a talkdown.
3) As far as 'who was PIC' is concerned, see 1) above
