Flights from East to West Take Longer Time

In a familiar phenomenon for passengers who traveled on long-distance flights, traveling from east to west takes longer than the trip itself in the opposite direction. Why? The rotation of the earth in the opposite direction of the clock makes part of the interpretation.

Markus Wahl from the German pilots' association (Vereinigung Cockpit) says: "Generally, at higher altitudes, wind often comes from the west, which is associated with the Earth's rotation."

Air currents from the equator to the poles are affected by the rotation of the Earth. Flights to the west usually face winds in the opposite direction, while flights to the east run in the same direction as the wind. These winds are also called jet streams, according to the German news agency.

"Normally eastward flights benefit from winds, because these favorable winds are the strongest," says Wahl.

Jet streams also affect short-distance flights, although the effect is too small, and causes a minor difference. "This effect often goes unnoticed amid the regular delays, that’s why you do not feel it as a passenger," Wahl says.

Tourist Coins Pose Giant Problem at N. Ireland's Famous Causeway Site

Northern Ireland's Giant Causeway draws close to one million visitors a year but their habit of wedging tiny coins in cracks between the rocks -- to bring love or luck -- is damaging the world-famous wonder.

Now authorities are urging tourists to keep their coins in their pockets to preserve the spectacular landscape.

Some 40,000 columns mark the causeway, Northern Ireland's first UNESCO World Heritage Site.

Geologists say the natural phenomenon was created by an outpouring of basalt lava 60 million years ago.

Legend has it that the causeway was formed by Irish giant Finn McCool.

In recent decades, visitors have pushed thousands of coins into fissures in the rocks.

The gesture is "a token of love or luck", according to Cliff Henry, the causeway's nature engagement officer.

But the coins rapidly corrode and expand, causing the basalt to flake and leaving "unsightly" rust-colored streaks, Henry told AFP.

He pointed to streaks on a rock and gingerly prized out a US cent with a set of keys.

"We get a lot of euros and dollar cents. But coins from literally all over the world -- any currency you can think of, pretty much -- we have had it here," he said.

A report by the British Geological Survey in 2021 revealed that the coins were "doing some serious damage" and something had to be done about it, he noted.

Signs are now in place around the site appealing to tourists to "leave no trace".
"Once some visitors see other people have done it, they feel that they need to add to it," causeway tour guide Joan Kennedy told AFP.

She and her colleagues now gently but firmly tell tourists to desist.

At the exit from the causeway, a US couple said they were "distressed" to hear of the damage the metal caused.

"Our guide mentioned as we came up that people had been putting coins into the stones. It's really terrible to hear that," said Robert Lewis, a 75-year-old from Florida.

"It's kind of like damaging any kind of nature when you are doing something like that, putting something foreign into nature. It's not good," said his wife, Geri, 70.

As part of a £30,000 ($40,000) conservation project, stone masons recently removed as many coins as they could -- without causing further damage -- from 10 test sites around the causeway.

Henry said the trial was successful and is to be expanded across the causeway.

"If we can get all those coins removed to start with that will help the situation and hopefully no more coins will be put in," he said.

"If visitors see fewer coins in the stones and hear appeals to stop the damaging practice, the problem can maybe be solved.

"We know that visitors love and cherish the Giant's Causeway, and many form deep personal connections to it, so we want this natural wonder to remain special for future generations."
