How Flying Works
The science and engineering of flight, explained clearly and correctly, without the myths many of us learned at school.
Every mechanism has a diagram you can play with, and every page lists its sources, including pilots’ own explanations where they exist.

The first explainer to read
How Does a Plane Actually Fly?
The real physics of lift — and why the popular explanation is a myth.

How engines are sold
Who Actually Makes Jet Engines, and Which Aircraft Use Them?
Four companies build nearly every airliner engine flying — and some jets let you choose.
Read it →Nervous about bumps?
Why Turbulence Isn't Dangerous
Certified for +2.5G/-1G. Real turbulence never gets close.

Learning paths
Ordered tracks through the explainers. Each article shows which stop you’re on and links to the next.
Aerodynamics & Flight
How wings make lift, and how aircraft climb, turn and cruise.
How Does a Plane Actually Fly?
The real physics of lift — and why the popular explanation is a myth.
What Every Part of a Plane’s Wing and Tail Does
Ailerons roll, elevators pitch, the rudder yaws, and spoilers do three jobs.
What Flaps and Slats Actually Do
A wing shaped for 500mph cruise is a genuinely different shape for landing.
What a Stall Actually Is (It's Not About Power)
It's an angle-of-attack problem, not an engine problem — and pulling back makes it worse.
How Does a Plane Actually Turn?
The rudder doesn't turn a plane — the bank does.
Why 35,000 Feet? Altitude, Concorde and Private Jets
Why Concorde, fighter jets and private jets all fly higher than a normal airliner.

Jet Streams: The World's Real Rivers of Wind
Four major jet streams circle the planet, plus a fifth that runs backwards.
Takeoff & Landing
Every phase of the runway, from V1 to touchdown.
What the Red, Green and White Lights on a Plane Mean
Red left, green right, white tail: a rule borrowed from 1848 steam ships.

V1, Vr, V2: What Happens During Takeoff
The three speeds called out on every single takeoff, and what each one means.
What Is a Rejected Takeoff, and What Is V1?
A calculated speed beyond which stopping on the runway is no longer the plan.
Why Planes Take Off and Land Into the Wind
A 20-knot headwind can cut a takeoff run by about a quarter.
.jpg?width=800)
What Is a Go-Around, and Why Is It Routine?
Roughly 1 to 4 in every 1,000 landings. Not an emergency — the safe default.

Why Some Landings Are Hard and Some Are Smooth
A firm touchdown is often the correct technique — not a mistake.

How Autoland Lands a Plane in Zero Visibility
In the thickest fog, the autopilot doesn't assist — it flies the whole landing.
What Do Runway Numbers Actually Mean?
The number is a compass heading — and it occasionally has to be repainted.
Weather
Lightning, turbulence, ice, ash and storms far away.
Why Turbulence Isn't Dangerous
Certified for +2.5G/-1G. Real turbulence never gets close.
.jpg?width=800)
What Happens When Lightning Strikes a Plane?
Struck about once a year on average — here's why almost nothing happens.

How De-Icing and Anti-Icing Actually Work
A thin layer of ice on a wing can be lethal — the real 1982 Air Florida crash shows why.
Why a Storm Nowhere Near You Can Delay Your Flight
Your gate is sunny, your flight is delayed anyway — here's why.
Why Does Volcanic Ash Ground Flights?
A 747 lost all four engines in 1982 — and restarted them mid-glide.
Cockpit & Systems
Autopilot, fly-by-wire, navigation and the warnings pilots hear.
What Autopilot Actually Does (And Doesn't)
It executes exactly what pilots tell it to — nothing more.
What Is Fly-By-Wire, and Why Does It Matter?
Since 1988, a computer sits between the stick and the control surfaces.
Airbus Sidestick vs Boeing Yoke
It's not hardware taste — it's who has final authority over the aircraft.
.jpg?width=800)
How Planes Navigate With No Landmarks in Sight
A 767 with both engines out glided to a safe landing, and the crew still found the runway.
What Do Cockpit Warnings Like TCAS and GPWS Mean?
When multiple alarms fire at once, there's a real trained order for which wins.
How Does a Black Box Actually Work?
It isn't black, and it isn't one box — the real 1950s invention story.
.jpg?width=800)
How Does Cabin Pressurization Actually Work?
At 40,000ft, useful consciousness lasts seconds without it.
Safety & Procedures
What happens when something goes wrong, and the rules that prepare for it.
What Happens If an Engine Fails Mid-Flight?
Why twin-engine jets are certified to fly for hours on one engine.
How Much Reserve Fuel Does an Airliner Actually Carry?
A 30 to 45-minute buffer, calculated in time, not gallons.
What Happens If Both Pilots Become Incapacitated?
The real 2005 Helios Airways tragedy, and what changed because of it.
What Is a Squawk Code? 7500, 7600, 7700 Explained
A four-digit code can tell every controller a flight is hijacked — without a word spoken.
The 90-Second Evacuation Rule, Explained
Every airliner has to prove 873 people can get out that fast, before it ever flies.
Why Airliners Don't Carry Passenger Parachutes
It's not cost-cutting — the doors can't even open at cruise altitude.
How Routes Are Planned — and Why Crews Change Mid-Flight
On an 18-hour nonstop, four pilots take turns flying it.
Engineering, Engines & Manufacturers
How airliners are built, the engines that power them, and the programmes behind them.
From Aluminium to Carbon Fibre: How Fuselages Evolved
Why the 787 is half composite — the science, the history, and the real downsides.

The Evolution of the Jet Engine
From Whittle's first turbojet to the open-fan engines being tested now.
Who Actually Makes Jet Engines, and Which Aircraft Use Them?
Four companies build nearly every airliner engine flying — and some jets let you choose.

Why Is the Boeing 777X Still Not Flying Passengers?
Due in 2020, now targeting 2027 — the real reasons behind seven years of delay.
For Travellers
Bags, seats and jet lag: the practical side of a flight.
Why Bags Go Missing on Connecting Flights
Transfers cause the biggest share of mishandled bags. Here’s why.
Why the Same Seat Feels Different on Each Plane
A 777 economy seat can be 18.5 or 17 inches wide. It depends on the layout.
Why Jet Lag Is Worse When You Fly East
Your body clock runs about 24 hours 11 minutes, so shrinking the day hurts more.
Airline Economics
Why tickets, bags and airports cost what they do.

Why Every Kilo Costs Money
Lift has to overcome weight — and that's where baggage fees actually come from.
The KPIs That Actually Run an Airline
Load factor, CASM, RASM, yield — plain English, real formulas.
What Airports Charge Airlines — and How Budget Carriers Dodge It
Landing fees, gate fees, jet bridge charges — and the real workarounds.
