While I do fly on a fairly regular basis, each trip requires on my part a process of letting go, of reaching the point on my flight departure date that I have made peace with the fact that my plane will crash, and when it doesn't, I am happily suprised.
I do understand that in its simplest terms that airplanes are able to fly due to two primary principles that contribute to the creation of lift, which is what makes flight possible. Those two principles are Bernoulli's Principle and Newton's Third Law. Let's break it down and look at each principle individually.
Bernoulli's Principle
By definition, Bernoulli's Principle states:For an inviscid flow, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure.
From a practical standpoint, this basically means that as a fluid (air, water, etc) moves faster, it's internal pressure decreases.
But how does this help an airplane create lift?
Basically, the shaping of the wing "fools" the air around it into thinking it is a long rotation cylinder, and forces the air to travel faster over the top of the wing than that of the bottom.
And according to Bernoulli's Principle, faster moving air = lower pressure. If we have lower pressure on top of the wing than we do on the bottom of the wing, we now have an inequality of pressures acting on the wing. There is more pressure pushing up on the bottom of the wing than there is on the top pushing down, which means we now have a total net force pushing up and we have lift.
Newton's 3rd Law
Newton's 3rd Law is defined as: To every action there is always an equal and opposite reaction.
Airplane wings are fixed onto the airframe of the plane at a slight angle. It may not be easy to see for the untrained eye, but upon a close examination of an wing's attachment point to the body of a plane, one will see a slight angle.This angle creates a deflection of air downward. As air hits the underside of the wing, even in straight-and-level cruise flight, it is forced downward. And according to Newton's 3rd Law, the forcing of the air downward causes an equal and opposite upward force on the wing, thus contributing to the creation of lift.
Makes sense. So what's the big deal about flying?
Statistics show (Click Here) that flying is one of the safest things that you can do.
If you are going to worry about dying, there are many more probable ways to die than on a commercial jet.
Take a look at the chart below, which shows the chance of fatalities on a commercial flight compared to other causes of death in the United States.
Notice that you are more likely to die from a bee sting than from a commercial flight. The number one killer in the United States is cardiovascular disease, with about eight hundred and eighty-five thousand deaths per year. Each of us has about a fifty percent (50%) chance of dying of cardiovascular disease.
Whenever we fly, we have a one one-hundred-thousandth of one percent (.000014%) chance of dying!

DEATH BY: YOUR ODDS

Let me say, that all of the above sounds great, reads wonderful, and seems like a no brainer, but it does not help make better my dislike of flying.
I hate flying and these statistics do nothing to change my feelings, Sure, you can walk out the door of your house and a piano can fall on your head, or lightning can strike you on a clear, sunny day. Life is one big crap shoot, but there is just something about airplanes that gives me the creeps.
Let's start with the obvious point. Nobody can be unaware that airplanes at 30,000 feet plus high do not always come gracefully and gently into land when something goes wrong. I know, cars are much more dangerous at 55 mph, but they seem a lot more natural than airplanes.
In real life this doesn't make any sense, I know the ugly true facts about the dangers of cars, those who drive them, Driving Under The Influence of Drugs (DUI) or Driving While Intoxicated (DWI). I really know what can and does horrifically happen much more frequently with cars and people than with airplanes.
Today's Blog post is not about what what I should know, but one of those things we all have within ourselves that seems to make no sense, and why I can't seem to get rid of it.
If something goes wrong with an airplane, your options are severely limited. All the time before the flight you have to think about the prospect of actually getting on the airplane. I am not good with heights. I also expect to be in control somewhat of my ability to travel, while I am moving in space. I enjoy checking the oil, tire pressures, kicking the tires, filling the gas tank, doing the pre-trip maintenance check up, things that I am able to do with a car. It gives me a sense of feeling comfortable, a false sense for sure, but it works.
In an airplane everything is done to you in an airplane. You have to deal with the idiots at security and all of their self importance as they literally strip you bare.
Once on the airplane, you're imprisoned with all your fears. You are told where to sit, when you must strap yourself in, which receptacle you may be sick, and what to eat and drink. You can't get out, or wind down the window, and half the time you don't even know what time zone you're in. If you decide to sing to yourself, the person in the next seat will probably elbow you in the ribs; and if your waking hours clash with what is supposedly a night time flight, you may feel obliged not to speak for ages.
And then, when you've finally landed safely, and may have to deal with the fact that your luggage has gone to another continent, you have a miserable time at your destination, thinking about how you've got to do it all again just to come home.
LEAVING ON A JET PLANE-JOHN DENVER
Why this great, innocent song, you ask? Because the lyrics say that the guy is leaving on a jet plane and he doesn’t know when he’ll be back again. Probably because he’s dead.
In the case of John Denver, he was ultimately killed flying an airplane he owned, not exactly reassuring.
So, yes I hate to fly, but I do fly often, and am a reasonably "good flyer" because as I previously stated I have already come to terms with everything that can go wrong on the flight. In essence, I have relinquished control to whatever, whomever controls that which we have absolutely no input as to its outcome.
Then there are the things that "they" don't want you to know.
Pilots falling asleep on the job (click here) is far more common than you might expect. In one British Airline Pilots Association’s survey of 500 commercial pilots, 56 percent admitted to having fallen asleep on the flight deck.
Twenty-nine percent had woken up to find the other pilot asleep.
Eighty-four percent said they believed their abilities had been compromised by tiredness in the past six months. While this might seem like unacceptable behavior, it is also very common.
