I'm Greg Fyfe, former NTSB air safety investigator.

I'm here today to answer your questions from the internet.

Anybody know where the safest spot is to sit on an airplane?

The best place to sit is where you can access an exit.

Over the wings or close proximity to either the forward exit or the rear exit.

Count the seats between the exit in front of you and the exits behind you.

Because airplane crashes, unfortunately, don't occur where the airplane is upright.

Knowing your position in relation to the closest exit is your best bet.

What do pilots say to the passengers of a plane when it is crashing?

Is it like in the movies or is it completely different?

One of the statements that you may hear is,

Ladies and gentlemen, we have a situation.

In a catastrophic or at least a more dire or urgent situation, you may not hear from the flight crew at all.

If anything, you may hear brace for impact because impact with the ground is imminent.

But you're not gonna hear a long discussion from the flight crew because their priority is to try and prevent the accident.

I am amazed that a flock of birds can bring a plane down.

The size of the bird is what really matters.

There have been a number of events that have taken place over the years.

The most recent one in history that a movie was made out of called The Miracle on the Hudson involving Captain Sully Sullenberger and First Officer Jeff Skiles.

The airplane had just taken off out of LaGuardia Airport.

They were climbing out and they ran through a flock of geese at about 3,000 feet.

Unfortunately, those geese were sucked into the engine.

With engines, they are built to withstand bird strikes to a certain extent.

But when you look at a 20 pound goose, that's like throwing a bowling ball into the front end of an airplane at two or 300 miles an hour.

The airplane then turned into a giant glider.

The flight crew had to make a decision and put the airplane down in the water.

There are other elements of bird strikes.

One of the bird strike accidents that I investigated several years ago involved an aircraft that was going into Sioux Falls, South Dakota at night.

And the pilots had forgotten one item on a checklist, windshield heat.

Now the windows on an airplane, because it's pressurized, are very thick.

Because it flies at high altitude and the window gets cold soaked, we heat the windshields to temper the glass so that if something does strike it, it will not shatter.

But that one missed item on a checklist put this flight crew in peril.

This is a picture from inside the cockpit of a bird that was struck.

It was a two pound duck, came through an inch and a half piece of glass.

The remnants then struck the captain, almost killed him.

The first officer had enough presence of mind, got on the flight controls and actually successfully landed the airplane.

I investigated a small general aviation accident where a very large bird, 22 pounds, actually came through the windscreen and struck both pilots, a flight instructor and a student, killed both of them.

We build aircraft to mitigate these kinds of dangers, but you can't build a birdproof aircraft.

Nw18graphics asks, during which flight stages do most aviation accidents occur?

We rarely have in-flight events at cruise altitude.

You're putting the most strain on engines.

Even though you're lighter, you're approaching the ground.

And so if there's any kind of weather event, wind shear, downdrafts, your margin of safety is decreased.

If we're so close to the ground and we're not going that fast, are we going to survive or do we have a better chance of survival?

But you also have a better chance of survival even in flight.

If you look at an airplane that was built in the 1940s or 1950s or 60s, today, the airplanes are so much better as far as their structure.

They have certain structures that break to absorb the energy.

They can withstand higher G-loads than those accidents that occurred with older airplanes.

Which accident investigation reports had the biggest impact on the industry or were the most controversial when they came out?

The one that is probably the most controversial is Malaysian Air MH370, the airplane that disappeared over the South Indian Ocean.

One of the reasons that I think MH370 has had such an impact is the fact that it's a mystery.

There's 2,000 feet of silt on the bottom of the ocean floor there.

If the airplane settled into that 2,000 feet of silt, you will never see that aircraft because it's so deep.

And in fact, the geography is like the Rocky Mountains.

If it crashed into one of the crevasses in that mountainous terrain, it may look like the terrain.

So any side scan sonar or any other technology may miss the aircraft.

One other controversial accident is TWA 800.

That was the aircraft that blew up off the coast of New York.

There are a lot of conspiracy theorists out there that still think that that airplane was shot down rather than having a mechanical malfunction in the center fuel tank that ended up leading to an explosion.

Kate Newens asks, where is Malaysia Airlines Flight 370?

These are questions that keep me up at night.

It's in the middle of the South Indian Ocean

22,000 feet deep on the bottom of the South Indian Ocean.

These are the questions that keep a lot of people up at night because it's the mystery.
