Riddle me this: can airplanes fly with only one wing?

Or can they reach supersonic speeds — still with a single wing?

The second conditional

If you answered no to both, you’re in for a surprise!

There’s still so much you probably didn’t know about airplanes, and neither did I — until

Can airplanes avoid hitting birds mid-flight?

Accidents happen, and sometimes planes must make an emergency landing because a bird smacked

into the windshield or got itself into one of the engines.

But this is usually the case during takeoff or landing, since birds don’t fly at the

Unless they’re wearing oxygen masks or something.

Measures taken at the airports to prevent this include loud sounds, like shooting blanks

into the air to scare off the birds from the runway, or even specially trained birds of

prey, who bully the other birds so that airplanes could take off safely.

How can a plane get struck by lightning and still continue its flight?

Normally, after it’s hit by lightning, an airplane is sent for inspection, but it can

still safely complete its current flight.

The fuselage conducts electricity well enough, and like with a lightning rod, the zap will

most probably strike one of the tips of the airplane — either one of the wings, or the

Then it seeks the ground but doesn’t find it, exiting from the tail.

It’s easier for electricity to roll through the surface of the plane than go inside, so

people on board are safe from its effects.

Still, lightning is powerful, and there can be some damage done to the airplane on the

Can the airplane’s equipment be disrupted by mobile phones?

The short answer is no, the longer answer is nooooooo -- your device can’t make any

of the plane’s electronics malfunction.

If you owned a smartphone about 5 years ago, you might remember that weird noise coming

out of any speakers around you when someone called you.

This normally doesn’t happen with modern devices, but the danger is still there.

Imagine a pilot trying to make out what the control is saying and all they hear is static

because someone hasn’t turned on the airplane mode?

I wouldn’t like to be on the same plane.

It might seem some sort of a magical button that allows you to keep your phone turned

on during the flight, but all it does is just cut any radio transmission, cellular or Bluetooth.

You aren’t likely to get reception at 30,000 feet anyway, but it can be important during

takeoff and landing, when you’ve still got signal.

And today the airplane mode is more flexible too, allowing Wi-Fi to work on board.

That’s why you can connect to the on-board entertainment system even with everything

Is it really a must to keep the window covers open during takeoff and landing?

Most incidents happen exactly at these times, so flight attendants need to have the clearest

With window screens open, they have better lighting inside, can see if anything goes

wrong outside, and the ground crew can also notice if something happens on board.

In case of emergency, rescuers should also be able to see inside for people trapped in

So only close that cover when you have safely climbed to unfathomable heights you can’t

Why are some contrails so short-lived, while others stay in the sky for a long time?

Contrails are a lot like clouds: they appear from water condensing high up.

Jet engines burn fuel, emitting CO2 and water vapor, as well as other gases.

Some of them allow water particles to collect around themselves, creating water droplets

If it’s already humid up there, then there’s more water, and the contrail is more prominent.

And if it’s cold, the droplets might turn into ice, staying behind for a much longer

Why aren’t there supersonic passenger airplanes?

There used to be two of them in the past, but both turned out to be unprofitable and

The British & French Concorde and the Russian Tu-144 Charger were the only commercial airplanes

to have broken the sound barrier in the 20th century.

They were thought to be the future of civil aviation, but the costs turned out to be just

too high, and a series of crashes sealed the fate of both supersonic jets.

Why are pilots’ and flight attendants’ seat belts so different from passengers’

Unlike passengers, flight attendants don’t have armrests or even comfortable enough cushions

All they have are small foldable seats near the galley.

That’s why they need not only a seat belt, like yours, but a shoulder strap as well.

Also, in an emergency, flight attendants have to be able to coordinate evacuation, so they

As for the pilots, they have a five-point harness that keeps them firmly in their seats.

This allows them to control the airplane even when it’s rocking and swaying like crazy.

Not that it’s going to rock and sway like crazy on your flight.

Why does traveling by car feel faster than by airplane?

Going 70 mph on an interstate makes you feel the drive and excitement of speed.

Flying at nearly 600 mph makes you drowsy at best.

This is because you don’t feel the actual speed of anything: you can only see how fast

you’re moving relative to other objects.

The closer, the faster — in a car, everything’s close to you, so you see trees, people, houses,
