People will often tell you that flying is statistically the safest form of transport, but it's really hard for that to resonate when the ground feels like a million miles away.
Those fears escalate too when turbulence hit the aircraft. From your seats you can't really know if the pilots have everything under control, so while the uncertainty of the situation consumes you, so does the expectancy of the worst.
This must have happened for those on board a passenger jet that was confronted by three water spouts as it approached a runway in Russia.
The huge sprouts appeared over the Black Sea off the coast of Sochi on Tuesday, Daily Mail reports, and forced the plane to weave in between them to ensure a safe landing.
Because of the weather, a number of other flights were diverted away from the airport, having to land at Anapa and Krasnodar instead.
Witnesses on the ground filmed and took pictures of the plane, worried about whether it would be able to make it down safely.
Something similar happened last month on an American Airlines flight 759, travelling from Athens to Philadelphia.
Ten people ended up injured from severe turbulence, which was totally unexpected for passengers or staff on board. This time however, footage was captured from inside the cabin...

The flight eventually landed safely later that afternoon, with three passengers and seven crew members being taken to hospital.
Back in May, similar footage came out of Russia, when major turbulence caused people to be thrown from their seats, along with food and luggage being strewn across the floor.
If you've ever been on a plane during turbulence, you'll know it can be a pretty terrifying experience. I've only been through mild turbulence and it was enough to have me praying, so I can't even imagine what these passengers went through.
The Aeroflot flight from Russia to Thailand hit turbulence an hour before landing, leaving at least 20 people suffering major injuries, including suspected broken spines, the Daily Mail reports.
The dramatic forage shows people lying in the aisles after being thrown into the air.
Evgenia Zibrova, who posted the video to Instagram, wrote: "Numerous air pockets one hour before landing led to broken bones, internal and external bleeding.
"Lots of people from the tail cabin have broken their noses, several people have probably broken their spines.
"Babies are covered in bruises, people lost consciousness. Thanks that we are still alive. Aeroflot, please help these people."
Vladimir Sosnov, deputy head of Russian Consulate in Thailand, said: "The injured suffered multiple fractures. There are both Russian and foreign citizens among them.
"Apparently, those who were injured did not have their seat belts fastened."

After landing injured passengers were rushed to hospital where two underwent emergency surgery.
A source told Interfax: "A Boeing 777 plane suddenly got into the zone of strong turbulence before starting to descend.
"There had been no order to fasten seat belts at that moment.
"As a result, the plane was jolted by hundreds of metres, and some passengers were thrown into the space between the chairs suffering traumas."
