Flight attendant gives answer about holes in plane windows after always being asked same question

Flight attendant gives answer about holes in plane windows after always being asked same question

It's actually very important for everyone's safety

If you’re not instantly closing your eyes the moment you buckle in for a flight, you’re probably gazing out the window ready to watch the Earth disappear below.

And as you stare out or look through your phone to begin that TikTok of your trip right from take-off, you might notice something a little weird.

It’s something that makes some plane passengers panic, the tiny little pinprick hole in the bottom of the window’s glass.

However, a flight attendant has finally given an answer about what these are for after constantly getting asked during work.

Henny Lim, who is an air steward for the Philippines-based airline Cebu Pacific, always has passengers asking her about those strange little holes in the window.

In a video shared to TikTok, she explained they’re called ‘bleed holes’.

And they’re quite important too as Lim wrote in the clip: “The tiny hole helps to balance the pressure difference between the cabin and the outside air.”

The flight attendant adds it has another purpose in releasing ‘moisture’ and stopping any ‘frost or condensation’ from blocking your view as you gaze out into the sky on your journey.

The Federal Aviation Administration (FAA) also confirmed the importance of the bleed hole to Business Insider.

It said: “Airplane windows consist of three separate panes. The outer pane deals with this air pressure difference. Thanks to the tiny holes in the middle pane, known as the 'bleed hole.' Its primary purpose is to balance air pressure.

“The ‘bleed hole’ allows pressure to balance between the passenger cabin and the air gap. Meaning the outer pane takes on the pressure while the middle pane acts as a fail-safe.”

Plus, like Lim said, the FAA explained it releases moisture from that air gap to prevent the window ‘from fogging up or frosting over’.

Something you might not have given as much thought as the holes is why the windows are round and not square - and the reason is a little horrifying.

Back in 1945, a flight from Rome to London suddenly exploded in the sky and a few months later, a similar incident took place from London to Johannesburg.

The one thing both aircrafts had in common was that their windows had sharp squared-off corners.

So, The Telegraph did an investigation into the twin tragedies, and found that the square shape of the windows resulted in metal fatigue. Specifically, the sharp corners would put more pressure on parts of the plane in high altitudes.

Airlines then changed the designs to more circular windows, as this allows the stress on the metal to flow more evenly around the edges.
