If you fly a lot, then maybe you’ve rolled over the possible uses for the tiny hole in your airplane window a time or two before. It actually serves two purposes: first, it allows airflow through to keep from too much pressure building in the plane and busting the window as it rises in altitude, and second, it keeps the windows from fogging up with all the warm breath of the passengers.
It's correct though, I can remember all the publicity when they were first introduced.
So if I try to save your life, but you see that it will make you uncomfortable, can I assume you will pass on the help?
Yes, had me totally confused .
