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:
