If, when flying in an airliner, a window is somehow perforated or its seal compromised, today’s invention might help.
As the cabin decompresses, anyone still strapped in near the window affected, can reach down and pull up a section of reinforced carpet from the floor nearby.
This would be clearly marked and mentioned in the flight safety video.
The tiles would be much wider than the window and could be coarsely applied to the aperture, forming a good enough seal to stop any further significant air loss.
There would be several such tiles near each window to allow for the possibility that one may be blown out. More than one tile could be used to form a multilayer plug for extra reassurance during the subsequent descent.
