Mi-17 helicopter flying among the buildings causes panic in Warsaw

On Jul. 27. 2013, an unusual sight in the skies over Warsaw caused some city residents to make panicked calls to the police: a huge Russian Mi-17 (Mi-171) helicopter was flying at very low altitude in the heart of the city.

It turned out that it was a chopper rented for the process of mounting an air conditioning device on a roof of one of the Warsaw banks.

Most probably cheaper than a crane, still a bit unusual to use a chopper to perform such heavy-duty task over the top of a downtown building.

Here are some pictures:
