What Will Happen If Planes Fly Almost to Space

Hey air-travelers! What’s your favorite time during a flight? The take-off, the landing? Or maybe the moment your plane climbs just above the clouds? Ahh, the view is magical. But have you ever wondered what would happen if your plane starts to climb even higher? Well, it's time to get some answers.

The first thing you should know is that the higher a plane flies, the faster it goes, and the cheaper it is. Air molecules are responsible for that. And since flying higher is more relaxed, more economic and safer, wouldn’t it make more sense if an airliner flew even higher? Actually, it’s a bit more complicated than that. Let's figure out!

SUMMARY:
- When a plane flies higher, less air is pushing down from above – therefore the air molecules spread out more, decreasing the air’s density.
- When an aircraft flies through less air molecules, it needs to adjust its speed in order to get enough air and lift itself.
- When the plane travels rapidly at higher altitudes, it consumes less fuel while taking you to your destination faster.
- All the turbulence, clouds, rain and bad weather in general, stay below the plane’s altitude, so we can enjoy a smooth, non-eventful flight.
- Pilots have more time to fix the problem and communicate with the controllers before they make an emergency landing.
- One of the main reasons a jet can’t fly higher is because there won’t be enough air flowing through its engine.
- When the air density decreases, the engine thrust does the same.
- When both the speed of sound and temperature drop in high altitudes, the true airspeed will increase. And at some point, they’ll meet. That’s what pilots call the coffin corner, and it’s as dangerous as it sounds.
- If a plane reaches that point, and it decelerates, it’ll go into a low speed stall. If it goes faster, it’ll end up in a high-speed stall. Neither of those are safe.
- Planes usually fly at around Mach 0.7 or 70% of the speed of sound. If an aircraft goes faster than that, it can cause shockwaves to form.
- If all these events happen in the coffin corner, it’ll break the aircraft into pieces.
- At certain altitudes, an aircraft has a minimum speed limit and a maximum speed limit.
- As the aircraft goes slower, the drag increases. The slower the jet goes, the more thrust it needs to be controlled.
- But the way they save a plane when it’s approaching supersonic speeds is a whole different story – and this is actually a bit more common.
- They slowly bring the thrust back a little bit, and gradually raise the air brakes. Everything is done in slow movements, because a sudden change can cause shockwaves that’ll roll the plane.

Hey there, BrightSiders! What was the most unforgettable flight you’ve ever had?

[karthikrajeshraj]

My favourite moment is when the flight attendant gives me food

[adiloz]

As aircraft engineering student, that literally explained 99% of my 3 years worth of aerodynamics module!!

[royfablooo]

Take a shot everytime this guy jokes over the simplest things.

[jadabdelkhalek]

Nobody:
Speaker: says a corny joke
Nobody:
Speaker: laughs at own joke

[Senaihh]

As a student pilot i like how this video gives lot of insights about what actually happens. Informative .

[girishkumar]

A group of Engineering professors were invited to fly in a plane. Right after they were comfortably seated, they were informed the plane was built by their students.
All but one got off their seats and headed frantically to the exits in maniacal panic.
The one lone professor that stayed put, calmly in his seat, was asked: "Why did you stay put?"
"I have plenty of confidence in my students. Knowing them, I for a fact can assure you this plane will never even start."

Yeah... Learned about the Coffin Corner. During my 7 years at the airport, I've never heard the British Airways and Air Canada pilots never mention that at all. Not even in their little meetings. I love flying, and always wanted to be a pilot. I have a real respect for every pilot out there.

When he said “I wish someone would decrease my density” I felt that

[zulaikhashaikh]

Now current favorite topic of Bright Side is Planeee...😅

[d.lovetheproducer]

"boy i wish someone would decrease my density" i lost concentration after that hahaha

[mikeryan]

This is a great explanation of several key aspects of flying, much batter than I was expecting.

[joshuatuazon]

Thanks BRIGHT SIDE! Love all your vids! You make my day brighter! 😂❤️❤️❤️

[kshiban]

We mostly fly around .80 Mach in newer airliners like the 767 for economy. Some of the older jets were a bit faster. The 727-100 could go .90 Mach but it burned a lot of extra fuel to do it. We can't go much faster than .82 Mach in the 767 because it puts us uncomfortably close to our maximum speed.

[wailoonthee]

I like the animations, it makes me easily understand the content. 😄

[cchangmiin]

I have always thought about the plane flying to space thanks for doing this video!😊

[anteeklund]

Not all supersonic planes were made for the military. Take the Concorde for example

[pac_jon]

airplanes can't "fly in space", the END.

[kaweesaflavia]

😂😂😂 I'VE LOVED THE LAUGH. MY HEART WAS ALREADY TREMBLING, IT BROUGHT IT BACK, THE '' LAUGH''. BUT THE CHESS THING😏😏

[timperrin]

Wow! I learned a lot! Very informative video, great explanation about the physics that control flight.
