why does land look like squares from an airplane

The horizontal white dumb-bell but with a black bar placed perpendicular to the shaft across each circular portion of the dumb-bell when displayed in a signal area indicates that aircraft are required to land and take off on runways only, but other manoeuvres need not be confined to runways and taxiways. Also how they leave letters with the air planes. (You can see an example in the image above.) So I liked it. The power station, which is bigger than 1800 football fields and is one the largest in the world, is owned in part by MidAmerican Renewables, a Berkshire Hathaway company and a nice visual representation of the enormity of Warren Buffets wealth.

Why do airplanes leave tracks in the sky?

Thanks for WONDERing with us! That's very cool! Have you ever seen that before?

Next up: A hydroelectric dam? Thanks for your patience.

With my own eyes.

By the way, this is why its so cold on airplanes.

We think it's WONDERful that you spend so much time outside! Return to that same spot each hour over the course of 3-4 hours. :), Welcome, Anya A!

:), Hi, Briana.S!

Those "exhaust trails" as you call it are nothing more the a toxic chemical concoction that they are spraying out to manufacture weather. Top photo by Glenn Young via Shutterstock.

Willis Orlando, Product Operations Specialist at Scotts Cheap Flights, says the round shape, while gentle on the eyes, is for a lot more than aesthetic purposes.

There are four basic signals.[2]. St. Elmo's Fire is usually blue or purple in color, but can also appear to be green. We think you're cool, Sydney!

As far as flying goes, there should be no issues flying above a hurricane in an aircraft equipped to monitor radar echo tops.".

The technology certainly must have improved somewhat through the years but the length and duration seems to depend more on what type of plane you are seeing.

is in the chem trails?

There is science behind what you are saying, but I want you to do something.

We respect everyone's viewpoint and want all our WONDER friends to feel comfortable sharing their thoughts on WONDERopolis.

Thanks for being our Wonder Friend!

Have you read any of the WONDERS about dogs?

:), Hi there, Tera, thanks for joining us at Wonderopolis today! The WONDER tells us that "today, skywriters take advantage of satellite navigation to program messages before flight, thereby increasing accuracy." The trails actually slowly broaden and BLANKET the entire sky. :), Welcome back, Ryan!

umm well i saw this in a movie but i didn't think it was possible. Make sure you know the facts before you have google put mis information about this subject on the web for children . and even though you're so high, there are huge mountains towering over you that you need to thread before you can get out of there. :). If you've ever seen an air show, you may have seen airplanes creating messages in the sky with what look like clouds. Tomorrows Wonder of the Day can be a real headache!

A horizontal red square panel with one yellow diagonal when displayed in a signal area indicates that owing to the bad state of the manoeuvring area, or for any other reason, special precautions must be observed in approaching to land or in landing.

Here's the thing, I am over 70 years old and I love a blue, blue sky or large beautiful clouds and have always gazed at the sky everytime I am outside (almost always). So much to see!

In this picture, the water is being sprayed just right above the crop, but moreso in the past, there were large "guns" shooting water in all directions from the top of the horizontal pipe.

There are strict regulations for drones in flight they can't come within 50 meters of people or structures or within a kilometer of airports, and can't get higher than 400 feet.

:), Those are great questions, Joe! Investigate geoengineering, as well as terms like Solar Radiation Management (SRM).

Thank you for your good sport and positive attitude when everyone is seemingly picking apart your article.

Are these contrails? I didn't know about this white tracks like why these plains are leaving this type of track N then I searched on Google N Wonderopolis you rally helped me in this topicThankyou So much And Thankyou So much Guys for sharing your experience with me and other People. The flashes in the sky look like dancing lightning bolts. So many people want to seepink lakes that scenic flights over them are now offered.

People have claimed to have flown over rainbows, but the laws of physics tell us that this is not possible.

Turns out, airplane windows were not always roundthey used to be square.

Essentially they are farmlands. Thats when square windows began to prove deadly. ?

The analysis of the crashes, and the similar injuries on the passengers, demonstrated that metal fatigue failureoriginating from the corners of the windowshad brought the planes down. Ever wonder what kinds of unusual objects pilots see from the air?

In these systems, water is pumped from a well in the center of the circle from an underground aquifer and distributed through a giant pipe hundreds of yards long; the whole systems pivots around a central point.

I never knew that airplane engine produces exhaust, just like the car do.

She is a Geo engineering whistle-blower . However, these high-altitude balloons could potentially cause a collision they are certainly not something a pilot wants to see at eye level when mid-flight. These trails do not dissipate. Always keep WONDERing! The array consists of 5.2 million cadmium/telluride thin film modules on fixed tilt mounts no more than six feet above the ground to reduce the visual impact. Thats a bit ironic considering 5,200,000 of anything is going to have a hell of a visual impact, even from 32,000 feet in the air. 12201 Sunrise Valley Drive Reston, VA 20192, Region 2: South Atlantic-Gulf (Includes Puerto Rico and the U.S. Virgin Islands), Region 12: Pacific Islands (American Samoa, Hawaii, Guam, Commonwealth of the Northern Mariana Islands).

Wonder #710: How Does Technology Change Lives?

They are spraying!

Thanks for WONDERing with us!

We'd suggest a Wonder Journey--searching the Internet or visiting your local library--to find out. And our government has definitely capitalized on this fact. If you're up for a challenge, try this fun experiment at home with just a few simple supplies. When there is a difference in the concentration of electrons between two objects, the potential difference induces an electric field. Thanks for WONDERing with us, today! :), Hi EH!

A coal-power plant?

Don't worry, though, you can still have fun checking out one or more of the following fun activities with a friend or family member: That's some aerodynamic / thermal aerodynamic stuff, there!

Thanks for joining the discussion and sharing your thoughts on this WONDER!

I have never seen it be done before but it looks pretty. We can see the trails that last all day. :), Great, Hung! They had very little depth and were shoulder-to-shoulder, hundreds of them, and they all had almost continuous lightning.''.

Do you ever make homemade cards for your friends and family members on their birthdays? I would watch the hell out of that. [1] At a pilot's command, the machines spray oil onto the plane's hot exhaust system, where it burns quickly and creates clouds of dense white smoke. I never knew most of those facts until today.

There is now a white haze that lingers and spreads out behind many of these planes.

Because this activity requires some clouds.

It can also be heard "singing" on the plane's radio a hissing sound that goes up and down the musical scale.

So, why the same airplane can stop doing it from one moment to another in same weather conditions? We think you're right, that it's not normal procedure to fly back and forth and completely cover the sky with contrails -- usually planes are just passing through, getting from point A to point B! :).

After a while, though, the plane's track fades and disappears into thin air.

You are murdering people for the govt.

After you get your answer to this airplane question, find answers to other airplane questions, like why airplane is also spelled aeroplane,how high airplanes actually fly, and whats up with those rear-facing airplane seats. This led to the oval design you see today, since stress could flow more evenly around a round window rather than building up at the corners of a square one. Planes leaves these contrails in the skies all day sometimes and change the sky to a nasty white haze. The landing T, showing the wind direction on an all-over landing field with the tail of the T pointing downwind.

Do you ever wonder what you're seeing when you look out of your airplane window and spot bizarre red pools or strange green circles on the ground below? :), Excellent argument, Laney! :-).

Just follow the directions to create your very own. We hope you have a great day, Tera!

We are glad you visited Wonderopolis. How are they similar? Please come back and visit us soon!

And just so you know, all commercial air liners planes don't make fake smoke. This article previously appeared in a different format as part ofThe AtlanticsNotes section, retired in 2021. Wow.

We think that should help clarify what is in the chemical trails!

Tell everybody about Wonderopolis and its wonders.

Interested in sharing Wonderopolis every day? It's really shocking that we've managed to bugger up something so huge.".

They were square up until the 1950s, during a time when planes flew slower and lower.

"It's called pivot irrigation," he said.

We talked to Gregory Dicum, author of the incredible aerial landscape guide Window Seat, about the weirdest and most beautiful views from an airplane. Skywriting goes way back. Those artificial clouds in the sky are actually exhaust gases from the airplane. Some airplanes even write words in the sky with their tracks! Why do you think that is? :), That sounds like a lot of fun, Monet Gray! WHAT are we breathing in and we want to know the truth.

Compare your observations. Here are some more window views that Dicum recommends.

The exhaust trails in the sky can make interesting visuals to look at. There are also pink lakes in British Columbia, Spain, and Canada. This condensed water vapor and mixture of ice crystals make up the cloud-like trails you see in the sky. In November 2018, pilots reported seeing UFOs off the coast of Ireland.
