I opened the window and the bird flew straight in.

Another scream came, then a window flew open with a crash.

Suddenly the window flew open with a violent push from without.

'The window in the floor above flew down into the street,' he said.

Suddenly, three stories up one building, a window flew open and a young woman stuck her head out.

When she came in it was as if the window flew open and the room filled with air and light.

Curtains billow and windows suddenly fly open in the middle of the night.

The window ahead of them flew open, outwards, scattering all the snow.

While I was closing the door the window flew open behind me.

At the fourth rap the window flew open as if something had exploded behind it.
