What's The Fastest Direction To Fly Around The World? DEBUNKED

[@DebunkedOfficial]

What's the worst flight you've ever had?

[@inshort58]

A very unwell person staggered towards me down the aisle and then puked right at me, I just managed to jump up on to my seat in time as it smattered all over the floor and front of my seat. I was then moved to another seat... a wet one.

Flying to Italy and couldn't land due to wind. They attempted 3 times so we has to go elsewhere

From a pilot - Well done :) FYI, we use winds aloft data to pick the best flight altitude - for max ground speed, and minimum fuel burn. Ex - Report near Denver - 18,000 feet - wind from 220 at 55 knots 24,000 feet - 230 at 76 knots 30,000 feet - 275 at 98 knots

@MarcPagan this might be a stupid question, but as a pilot, can you ‘feel’ the difference?

[@MarcPagan]

@@accidentinstrument Feel the dif in wind speeds and direction? If that's the question - No, but wind's impact on ground speed and required course correction are evident.

Interesting question: If SpaceX Starship Earth to Earth ever happens (I'm doubtful), would flights on it be faster in the East to West direction due to the carousel explanation, since air currents wouldn't have a heavy impact on a rocket's flight path? Conservation of momentum does very much exist, but we have to remember we're talking about a sphere. Without modelling in the atmosphere the hovering harrier would have to travel a longer distance through a full rotation of the Earth, so if it was able to hover perfectly vertical the entire time the momentum conserved from taking off from the Earth wouldn't be quite enough to complete a full rotation, say, 500m off the ground in the same amount of time as Earth. Albiet obviously that's a small enough change for a human pilot to easily correct for very slightly and by using the environment as reference points... But if we're talking about rocket travel, well first of all the peak altitude is higher, the atmosphere isn't that much of a factor in speed, and we're not considering a "hovering" scenario. I'm legitimately curious if the situation would be reversed for them (and my experience playing Kerbal of having rockets launched straight vertical usually drifting west a bit whilst in space is telling me it's likely).

[@starmanxvi]

Yes, rockets travel much faster (~16,000 mph for p2p) than the Earth's rotation in either direction. Flying eastwards it would get a 1000 mph boost, and flying westward it would get 1000 mph slowed, this is why rockets launch east the majority of the time. You can think of this like standing on another conveyor belt (B) next to the bear (A) and you are moving much faster. When both conveyor belts are moving in the same direction, say A has a speed of 1 m/s and B has one of 3 m/s, meaning that their speed relative to each other is 2 m/s. Now let's say they are traveling opposite directions at the same speeds, their relative speed would now be 4 m/s while the independent velocity of each conveyor belt is still the same. This analogy doesn't work for airplanes as they don't have enough speed to overcome the Earth's rotation unlike rockets, this is definitely something you could try out more yourself in KSP as it is quite a fun experiment and a great use of the game's capabilities. Great question and hope this helps. (Edit: Holy crap I just took a look at your channel and you've been playing Kerbal for a few years less than I've been alive lol, it's so weird to see the game in its early stages like that.)

I like the fact the map has 2 Icelands on it. Noticed it at the 9 minute mark

[@jaggerbushOG]

I flew from Pittsburgh to Hong Kong - then traveled around and ended in Singapore. Flew Singapore to London to Pittsburgh. Now, the return flight was just as I imagined - Singapore to London on a straight line over Afghanistan. Spent a day in London and then across the Atlantic to Pittsburgh (against head winds) - but Pitt to HKG was a bit of a surprise. It was 22 hours but over the artic, down over Russia to HKG.

[@matijakralj8860]

But what about long-range shooting? "Coriolis effect is a product of the Earth’s rotation and, in the case of firearms, moves the target away from the original point of aim when the bullet finally arrives. Total deviation is determined by time of flight, shot direction (azimuth), how fast the planet is moving at both the firing point and target and more. It’s dictated by a lesser-known Coriolis force that, thankfully, includes inertia as a key component" And: "All shots, regardless of hemisphere, will impact lower than expected when sent west and high when traveling east." And this: "The Earth is a sphere. So, targets to the west are rotating toward you and rising slightly on the horizon (atop the planet’s circumference). The bullet, in theory, continues toward your point of aim, which is no longer there because it’s moved up."

[@riverbender9898]

Thanks for great videos.

[@brianstieben9284]

Nice video! I have one doubt. At minute 5:44. Why does the hot air go north (and south also I guess)?

[@icefreez3r815]

Air is heated up at the ground, rises up, therefore increases pressure at high altitudes. Less air north and south -> wind from high pressure to low pressure

[@brianstieben9284]

[@MrPinkfloydian]

Very interesting and hilarious as always. I even got left with two (dumb!) questions. # One - How do pilots adjust the course according to the jetstream... since they can't open the window, lick their finger, and stretch the arm out so they can... feeeeel the jetstream? (😂) I'm off to search for what technology might that be 👍 # Two - Soooo could it be faster to return to the USA from London... flying east? 🤔 I'm off searching for the duration of the flight from London to Australia and Australia to the USA to make sure the flights keep going east... even though I'm certain that a flight from the USA to London does not equals to a flight around half of the Earth. But that's the idea... # Three - How long/length could compensate flying East from London? 🤔... I'm off to a chatbot right away 😂

Waitaminute. "Air warmed at the equator rises, it moves toward the poles." I think that one warranted a lot more explanation -- it implies that the north pole is "up", and that's why the warm air moves there. The only hint you left that suggests that's not what's actually happening is that you clarified that the air only moves "up" in the northern hemisphere. I'm actually not 100% sure of the actual mechanism. I *think* it's that warm air, high energy air tends to expand to evenly distribute that energy into cooler, lower energy air (thus, the warm air at the equator moves toward the poles). Right?

[@GoogleSucks-i1d]

The idea that heat goes up is a misconception. Heat travels to less heated areas whether it's up or down. This can be demonstrated by putting a warm bowl of soup in your lap. The heat will go down. This is called convection. When you have a large volume of heated air gravity will play a role. Gas compress when cooled and expanded when heated. So not only can warm ground air transfer it's heat upward to cooler air the heated air itself will move. This is because the same volume of air contains less air molecules than an equal volume of cooler air. Gravity will cause the heavier air to move down which will push the less dense, i.e. warmer, air upwards. This is generally why people think heat rises and is also how hot air balloons. Bonus fact: when you include the different speeds the air moves you get the cause of all the weather in the world. When you include the vapor pressure, the capability of warmer air to hold more water, and land formations like mountains you get everything you need for all the weather on the entire planet.

[@accidentinstrument]

@user-ln1ec9qr5y heat from the bowl of soup into your lap is conduction rather than convection I think

I will guess its like the gulf stream but happens in the air.

[@JohnSmithEx]

Another physical effect not mentioned in the video is that flying eastward results in a greater angular velocity compared to flying westward. That's because the angular velocity of the plane is added to the angular velocity of the earth. This results to an increased centrifugal force, reducing the effort required by the engines to maintain the plane's altitude. The effect of this phenomenon at reducing the duration of the flight is minuscule compared to the effect of the winds.

[@nkosikhonadube241]

You are actually wrong this time because the coriolis force actually states that winds blow from a point of high pressure to a point of low pressure towards their left. Which means that winds blow from the poles toward the equator towards their left. Which means that in the northern hemisphere, winds blow from the west to the east.

[@Koh-Wei-Jian]

Wind. A single word can summarize this 11min video

[@harzemyalcinkaya]

Exactly. I got bored at minute 1 and barely finished minute 2. I guess the point they were trying to get was in the opposite direction of the wind.

[@lonelyPorterCH]

Watching this at the airport travelling from switzerland to Los Angeles ^^ Lets see which way is faster (if any)

[@reshpeck]

Obviously you're going to fly slower into a headwind, but wouldn't the change in latitude have an effect as well? As you're moving south along your route from London your initial ground level momentum becomes relatively lower in comparison to the ground at the faster moving lower latitudes of New York, and on the return trip you'd be gaining on the ground in London. Surely this is a factor as well?

[@burieddreamer]

And why do the winds from the equator go north? It's not accurate when you say "it goes up" to describe "going north."

[@randomgamerkid8172]

Hi

[@Nam3Iess]

As a drone operator, I figured this one out by myself 😂

[@DeaconHo]

Okay this makes sense.

[@timothytumusiime2903]

So.... With the difference in rotational speed at the poles and the equator, what would happen if a person was suddenly teleported from one to the other Would the airspeed slam into them and pulp their insides???

[@DebunkedOfficial]

I like the way your mind works 🤓

[@blasterdush4998]

shouldnt the south wind be to the other side?

[@MariaMartinez-researcher]

If you mean the wind in the Southern Hemisphere should go in the opposite direction, no, it shouldn't, as the whole Earth rotates in the same direction, towards the East. The Coriolis Effect and jet streams work the same North and South. There is a difference, though, regarding the deviation of the currents of air from the Equator to the Poles, and that's why hurricanes, cyclones, turn counterclockwise in the North Hemisphere and clockwise in the Southern Hemisphere. Water in a bathtub or toilet can do it too, but it is too small a quantity as to be affected consistently.

[@dwaynelangerhr6985]

It is very simple. If you fly to from London to New York it takes longer because London uses the Meric system and we here in the states don't.

[@Soundbrigade]

I think it has to do with relativistic effects from Einsteins equations… 🤔 Honestly, a very good explanation and definitely a “flat earth killer”.
