Smashing the “Coffee in an Airplane” lie.

Hello lovely readers! What a hard day it has been for us today. Many times during debates, we heard the same ridiculous argument. “Because I can walk in an airplane, that proves that we can move so fast and not feel it.” Well, my pretties, that’s a scientific fallacy of the highest order. Let’s talk about it! 😀

Disclaimer: I live with DiD. I have multiple alters and I say “We” a lot simply because we truly are a package deal and proud of it, so, deal with it. You may think I’m crazy but I’m certainly not stupid. Would you like to listen to this blog rather than read? Here you are!

So, many times in debates, we always heard the same debating tactic. “I can walk in an airplane in flight, so that proves relative motion.” Not so fast! It’s not that simple and never has been. If anything, this argument is the highest order of scientific fallacy we have EVER heard and are happy to destroy this argument, again.

At first, we thought this was something that someone saw on some Reddit post because it’s that ridiculous. After some quick googling, we found the culprit.

So we are in a Jetliner at say, 600 miles per hour. We are sitting with our cup of coffee, sipping away and checking out the hot chick in the seat next to us. What does this prove? Nothing other than we are sitting in an airplane in flight, looking at a hot chick. That’s it and nothing more.

The reality of the situation can be broken down into two distinct sections. Let’s tackle em, together!

The insanity of the argument is easily understood once you apply those things called “Common sense” and “Observable FACT“.

The reason you don’t feel the force of movement generated by thrust is simple. The headwind that generates the force of drag, applied by thrust, of which you would incur, is being DEFLECTED away from you, the coffee cup and the hot chick who’s sitting inside a pressurized tube. Let’s look again at the “Force of Drag”.

In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid.[1] This can exist between two fluid layers (or surfaces) or a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, drag forces depend on velocity.[2][3] Drag force is proportional to the velocity for a laminar flow and the squared velocity for a turbulent flow. Even though the ultimate cause of a drag is viscous friction, the turbulent drag is independent of viscosity.[4]  SRC1 See bottom

The forces of drag generated by thrust that would impact the surface area of your body, the hot chick’s body, the coffee and everything inside the craft is being deflected by the aluminum shell of the aircraft itself. It’s that simple.

If everyone was seated on top of the aircraft, you most certainly would feel the force of both your airspeed and the headwind that you would incur because of it. Not to mention, you would eventually pass out. You are moving so fast, it would be virtually impossible to breathe, move or anything else.  You certainly would feel TREMENDOUS force.

The very fact that the interior of a commercial airliner is pressurized should tell you something. The reason aircraft are pressurized is so that human beings can breathe. The higher in altitude you go, the thinner the air gets.

Eventually, you will go so high into the “Atmosphere” that becomes less and less dense, that you will eventually pass out from lack of oxygen. This is why aircraft are equipped with breathing masks, in case of decompression.

Sucking a straw with a finger on one end and watching it crinkle up is a perfect example of aircraft decompression.

An aircraft has to be pressurized and the air inside of it stabilized. The only reason it remains in the cabin is because it, also, is being protected from the tremendous Force of Drag that the aircraft’s engine(s) create(s) by producing thrust.


This myth of the “Relative motion” in an aircraft  is a scientific fallacy for 4 major reasons:

  1.  The Earth isn’t protected by an aluminum shell, it doesn’t have man made engines.
  2. Humans cannot produce the thrust to move as fast as a commercial jetliner at high altitude, either.
  3. We don’t work by analogy. Anyone who chooses to present evidence by analogy hasn’t done their homework and is acting lazy.
  4. We don’t debate with anyone that would rather use analogies as observable science, rather than actual facts and actual science.

We can do this all night long. Debunking these myths is very easy when you apply that little thing called “Logic” that so many brainwashed individuals lack.
