Have you ever looked at a flight path on a map and wondered why airplanes take curved routes instead of flying in a straight line? Wouldn’t flying in a direct line be more fuel-efficient and faster? At first glance, it seems logical that a shorter distance would result in less fuel consumption, but in reality, aviation is far more complex.
Several factors determine flight paths, including the Earth’s shape, jet streams, weather conditions, and air traffic regulations. Let’s break down why airplanes rarely fly in a straight line and how their curved paths actually make flights more efficient.
The Earth’s Shape and the Great Circle Route

One of the biggest reasons airplanes don’t fly in a straight line is the Earth’s curvature. While we often view flight maps as flat, the Earth is a sphere, and the shortest path between two points is actually an arc called the Great Circle Route.
If you take a globe and use a string to connect two distant locations, you’ll notice that the shortest route often curves rather than follows a straight path. This is why flights from New York to Tokyo pass over the Arctic region rather than flying directly west across the Pacific Ocean.
Using the Great Circle Route helps planes save both time and fuel, even though it appears curved on a flat map.
Jet Streams and Weather Conditions Impact Flight Paths
Another key factor affecting airplane routes is jet streams—high-altitude wind currents that move at speeds of up to 200 mph (320 km/h). Pilots strategically plan routes to take advantage of these strong winds when possible.

Flying with jet streams allows an airplane to get an extra push, helping it move faster while burning less fuel. Flying against a jet stream can slow down the plane significantly, increasing fuel consumption. Pilots often adjust routes to avoid strong headwinds, even if it means flying a longer distance.
Additionally, storms, turbulence, and severe weather conditions also play a role in determining flight paths. Airplanes may adjust mid-flight to bypass dangerous weather zones, thunderstorms, or areas with extreme turbulence.
Air Traffic Control and Flight Regulations
Air traffic isn’t a free-for-all where planes can just fly wherever they want. There are strict regulations set by aviation authorities and air traffic control (ATC) that dictate flight routes.
Some of these rules include restricted airspace, where certain areas, such as military zones, national security locations, and political zones, prohibit commercial flights from entering. Predefined flight corridors exist to avoid mid-air collisions, ensuring flights follow established air traffic lanes. Major airports handle hundreds of flights daily, so ATC ensures safe and efficient arrivals and departures.
Due to these regulations, airplanes cannot always take the most direct path and must follow designated routes instead.
Avoiding Air Turbulence for Passenger Comfort
Turbulence can make a flight uncomfortable, and pilots actively adjust routes to minimize rough air conditions. There are different types of turbulence, including thermal turbulence caused by warm air rising from the ground. Flying at higher altitudes helps avoid this.

Mechanical turbulence happens near mountains and rough terrains where wind patterns shift unpredictably. Clear-Air Turbulence (CAT) is sudden, strong air currents in high altitudes that are difficult to predict.
To ensure a smoother ride for passengers, pilots may deviate from the shortest path to avoid these turbulent areas.
Why Do Airplanes Sometimes Ascend Before Landing?
If you’ve ever been on a flight where the plane suddenly climbs just before landing, you might have felt a bit concerned. This maneuver is known as a go-around and is actually a common and safe aviation practice.
Some reasons why pilots perform a go-around include runway clearance issues. If another plane hasn’t cleared the runway in time, pilots must abort the landing and circle back. Poor weather conditions, such as poor visibility, strong crosswinds, or sudden gusts, can make a landing unsafe. If a plane is too fast, too high, or not properly aligned with the runway, the pilot will ascend and try again for a safer landing.
Go-arounds are standard procedures in aviation and ensure passenger safety above all else.
The World’s Longest Non-Stop Flight
While most flights follow curved paths, some routes push the limits of non-stop travel. The longest direct commercial flight in the world is from Singapore to Newark, New Jersey, USA.
This flight covers a distance of 10,400 miles (16,700 km) and takes approximately 18 hours and 45 minutes. It follows a carefully optimized path to balance fuel efficiency, wind conditions, and passenger comfort.

What Happens If a Plane Suddenly Loses Cabin Pressure?
A sudden drop in cabin pressure is often portrayed as a dramatic event in movies, but in reality, pilots are well-trained to handle it calmly.
When this happens, oxygen masks automatically deploy, and passengers should put them on immediately and breathe normally. The plane will descend to a safe altitude where oxygen levels are sufficient for breathing. The flight crew will assess the situation and communicate with passengers.
Losing cabin pressure doesn’t mean the plane will crash—pilots follow strict safety protocols to handle such incidents efficiently.
Final Thoughts: Why Curved Flight Paths Are More Efficient
While it may seem counterintuitive, airplanes take curved routes instead of straight lines to optimize flight efficiency, fuel usage, and passenger safety. Factors such as the Earth’s shape, jet streams, air traffic control, and weather conditions all play a crucial role in determining flight paths.
So next time you’re on a plane and see the route map displaying a curved flight path, remember there’s a lot of science and planning behind it to ensure you reach your destination as safely and efficiently as possible.
Nurse Gives Woman the Wrong Baby, Then New Mother Turns Pale — Story of the Day

The nurse examined Lucy’s twins before discharge, but Lucy was shocked when she returned them. The nurse had brought two baby girls after the examination, and Lucy had given birth to one boy and one girl.
Lucy and her husband Ross had been trying to conceive for a long time, and when they discovered they were expecting twins, they were over the moon.
The ultrasound had revealed they would be having a boy and a girl, and the couple was eagerly awaiting the arrival of the twins. However, when the nurse brought the children post-examination, they were both girls. Lucy’s face turned pale.

“Where has my son gone? What exactly did you do to him? And whose baby is this other girl?” she screamed, gazing at the nurse who had just brought the kids in.
“They are your daughters, ma’am,” the nurse, Savannah, said, her eyes fixated on the documents. “I double-checked the reports and I’m confident there is no error.”
“Have you lost your senses?” Lucy snapped. “I have all the reports with me as proof that I was supposed to deliver a boy and a girl. And I was informed about the same after delivery. There’s no way they’re both girls!”
Lucy noticed the fear in the nurse’s eyes when she looked up from her reports. She was about to say something to her when Dr. Linda Carter walked in. “Would you please keep quiet, ma’am? This is a hospital, and there are other patients,” she explained to Lucy.
“Quiet? Seriously?” Lucy glared at her. “Your nurse brings me a random child, then tells me she’s not wrong! Is that how your hospital administration operates? Should I contact the chief doctor and inform him of the situation?”
“I agree with my wife, doctor. We don’t want to create a scene either,” Ross intervened. “But your nurse is lying. We don’t know why she’s doing that, but if we don’t get our son back, we’ll have to call the police!”
“Please, sir, calm down,” Dr. Carter said. “I’m sure there’s just some misunderstanding. Savannah has been working at this hospital for several years. Perhaps she brought the wrong documents. Savannah, may I have a look at the papers?” Dr. Carter inquired. But Savannah didn’t give it to her and instead started stammering, “There’s no need, ma’am…I mean, I checked it, and they’re fine.”

Dr. Carter sensed something was wrong and softly told her, “It’s fine. Let me quickly check the reports.” However, when she read through them, she realized Lucy was correct.
“Please give me a minute, ma’am,” she said as she flipped through the pages. “I assume Savannah brought the incorrect paperwork. There was another patient named Lucy Matthews, and Savannah got confused.”
“I’m glad you noticed your mistake,” Lucy said, glaring at her. “I would recommend that you hire responsible people as members of the staff the next time!”
“I’m sorry, ma’am,” Dr. Carter apologized again as she turned to face Savannah. “Would you mind accompanying me, Savannah? I need you to find the correct reports for me.”
Savannah swiftly followed Dr. Carter, but Lucy spotted the tears in her eyes as she walked away. She got a strange feeling Dr. Carter and Savannah were up to something, so she decided to follow them.
She watched them both enter Dr. Carter’s clinic and then heard someone crying. It had to be Savannah, she reasoned. Fortunately, the door was slightly ajar, so Lucy sat on one of the chairs just outside the room and listened to what they were saying.
“What were you thinking, Savannah?” Dr. Carter spoke in a firm tone. “Lucy Matthews delivered twins: a boy and a girl at 10:30 a.m. today. Even the reports said that. Why are you lying to them? Be honest!”

“I didn’t have a choice, ma’am,” Savannah sobbed. “That other newborn girl belongs to my sister. Her spouse had abandoned her after he learned about the pregnancy, and unfortunately, she didn’t make it post-delivery. I could have adopted her, but my husband refused.”
“Why don’t you place her in a nursing home?” Dr. Carter proposed. “She’d be well taken care of there.”
“I’m afraid I can’t, ma’am. It was my sister’s last wish for her daughter to grow up in a loving home,” Savannah sobbed.
“When I saw Mrs. Matthews this morning and how she and her husband were supporting each other, I thought they would be a beautiful family for her. So I decided to swap Mrs. Matthew’s son with my sister’s daughter and place him in a nursing home instead.”
“But that’s not right, Savannah,” Dr. Carter pointed out. “We can’t let that happen. Get Mrs. Matthews’ son right now. And, yes, this should stay confidential between us. Let me see what I can do for you.”
Lucy’s eyes had welled up when she heard the story. There wasn’t a nefarious intention behind exchanging the kids. A helpless woman wanted her niece to end up in a lovely family. I feel sorry for the child, honestly. Lucy pondered as she returned to her room.
A few minutes later, Dr. Carter returned to Lucy’s room and handed over her newborn son. “Sorry about the mixup, ma’am. I apologize on behalf of my staff,” Dr. Carter said.

Having overheard the whole story earlier, Lucy, decided not to file a complaint against her. But every time she tried to sleep at home that night, her thoughts returned to the poor child, and her innocent face flashed straight in front of her eyes.
“I can’t forget about her, Ross,” Lucy told her husband at breakfast the next day. “I had a dream yesterday in which I saw a girl who had come to our house by mistake and was living peacefully with us. I know it doesn’t make sense, but I can’t get that out of my head.”
“It’s because of what happened yesterday, honey,” Ross explained. “Try to distract yourself with something else. How about we go somewhere? You’ll feel better.”
“No, Ross,” Lucy looked at him. “I don’t feel like leaving that child alone. I want to adopt her.”
“But honey!” Ross cried. “Are you sure? We already have two children to look after, and a third would be far too much! Don’t make emotional decisions! We need to be practical.”
“I understand, Ross, but please. I can’t persuade myself. I pondered it all night and decided to adopt her. Can we please go to the hospital today?”
“Well, honey. I am there with you in all your decisions, but I’m worried it’ll be too much work for you.”
“I can manage that, Ross. Please?” Lucy insisted.

Ross initially opposed the adoption, but his feelings changed when he held the child in his arms. She had brown eyes with a slight green tinge, and she kept staring at him. Ross was moved by her innocent looks, to say the least.
“I’m delighted you considered adopting her, Mr. and Mrs. Matthews. She is indeed lucky,” the doctor told them.
“Well, doctor, we tried a lot for kids, and now, when a child wants to come to us, we can’t just let it go. Just let me know when we can take her home,” Lucy said.
“It’ll take some time, but for now, I’ll submit the documents to expedite the process.”
As the doctor had said, it took some time, but Lucy and Ross had no regrets about their decision. When they brought the child home, they felt as if their family was finally complete. They named the baby girl Amelia.
Savannah visited them after learning Lucy and Ross had adopted the child and couldn’t stop thanking them. Since then, she’s become a regular at the Matthews’, and she mostly spends the weekends with Lucy’s kids: the twins Sia and Mark and Amelia.
What can we learn from this story?
- Relationships are formed through love and care, not necessarily by blood. Lucy and Ross’s adoption of Amelia as their kid is a beautiful example of this.
- Some accidents are beautiful. Savannah brought Amelia to Lucy simply because she wanted her to be adopted by a good family, and in the end, the poor child was blessed with a lovely family.
