When you travel on an airplane, you presume it to keep you safe and sound until you land to your destination. It's not much to expect, really. But, what if I tell you that there are holes punched at the bottom of the window.
Have you not noticed it before? Oh, damn! I can only imagine the panic you must feel at this very moment. Worry not! The hole is not planned out to get you sucked out in the open air, 30, 000 feet above the ground. But, if it's not a well-planned conspiracy of murdering you, then why?
Oh, well this is exactly why!
Do not panic, guys. Do not panic.
Okay, maybe exaggeration is officially my forte, but hey curiosity got the better of me.
Robbie from io9 tracked down the maintenance manual copy for the Boeing 737 on the WikiLeaks and then contacted Marlowe Moncur, the director of the Technology in GKN Aerospace, which by the way is the world leader in the passenger cabin window design development.
Robbie surely took it to another level by contacting the very best in the business. That is what I call smart.
The hole is for maintaining pressure in the cabin.
The cabin windows are generally comprised of inner, middle and outer panes which are made up of synthetic resin. The holes are mostly in the middle pane whereas the inner pane is a failsafe in case the outer pane fractures because of one reason or the other.
Share the article with as many as you can, so that if anyone notices that hole, he/she doesn't panic.
