Hidden meaning behind black triangles you see in some planes

Hidden meaning behind black triangles you see in some planes

The strange black triangles you see in plane cabins have been explained

Those weird black triangle stickers you sometimes see in plane cabins are actually there for a very important reason.

Now, for most of us, the first thing we do once we get on a plane is whack the headphones on and sit quietly until that drinks trolley comes along.

Instead, others will read the safety manual and notice every little thing - from the little round holes in the windows, to realising the windows are in fact round and not square.

Very quickly, this was because of an incident in 1945 when a plane from Rome took off to London.

35 people were aboard the aircraft when it suddenly exploded in the sky and landed in the Mediterranean Sea.

A few months later, the same sort of incident took place with a plane on its way 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.

Once this investigation was published, airlines changed their designs to make windows more circular, as this allows the stress on the metal to flow more evenly around the edges.

There's a reason why plane windows are round and not square.

Now, the reason why you're here, flight attendant Henny Lim has explained the situation with these little black triangle stickers.

“Passengers sitting next to the triangles get the best view of the wings,” the cabin crew member said.

She also noted that the wing view windows are the 'best vantage points for the slats and flaps outside'.

“If you’re flying an airline that allows you to choose your own seat, look for one of the triangles in the cabin,” she continued.

“Anybody who loves taking window shots or videos will get the best view over the wings from these seats.”

In the comments, one person wrote: "Very informative."

"Wow interesting," a second added, while a third commented: "Thanks so much for the tip."

In another video, Henny explained the reason why flight attendants sit on their hands in the 'bracing position'.

“This position involves fastening the seatbelt securely, sitting upright, sitting on hands, palms upright, thumbs tuck and arms are loose with feet on the floor,” she said.

“The aim is to keep the body in a rigid pose so that if there was any impact from an unplanned emergency, the body is less damaged.”

The pose basically 'keeps body movement restricted so that there is less chance of injury if there was an impact'.
