The ATR went back to WAW on "special permit" last night for cleaning.
There was a danger of some damage, but also the security
markings were covered by the paint, so
"all the passengers were seated on the clean side".

Today the man who did it, and was stupid enough to
put the picture on his blog, got arrested.
He may serve up to 5 years...
