A window frame, torn out by an explosion from the eighteenth floor window of a high-rise building on Vosstaniya Square, rushed down, overtaking along the way a bunch of small glass fragments that rained down from the windows of three floors above the eighteenth and five below. The frame picked up speed, its flight path turned into a steep straight line. Cutting through the air with a whistle, it crashed into the roof of an Audi standing on the site in front of the high-rise building, broke through it and got stuck in the car, towering above it like a monument symbolizing the rampant terrorism in the current capital of Russia.
