Tallinn Defence EXPO: Counter-drone systems and robot soldiers steal the show Drones have changed the face of war in Ukraine. At the Tallinn Defence EXPO, Estonian companies showed the counter-drone systems and battlefield robots they say Europe now needs. READ MORE : Euronews Next is a future-focus

Why do airplanes dim cabin lights before takeoff and landing? It is a deliberate safety procedure: dimming pre-adapts passengers' eyes to darkness for faster evacuations, makes exit signs and floor path lighting stand out, and lets the crew see exterior hazards through the windows.

That pinprick hole in your airplane window is not damage. It is a breather hole that balances pressure across the window panes and stops fogging, and this explainer covers how the three-pane design works.

Those white lines are contrails: ice crystals formed when hot, moist engine exhaust meets freezing air at cruising altitude. Whether they vanish or linger depends on humidity.

Airline miles usually expire after a period of inactivity, not because you didn't fly. A small portal purchase, a dining reward, or a tiny redemption is often enough to reset the clock and protect your balance.

Those curved tips on modern airplane wings are called winglets, and they cut drag in a way that saves real fuel on every flight.

Flying a drone near an airport is one of the fastest ways to break the law by accident. Here is how controlled airspace, authorisation, and distance rules actually work.

Most jets cruise between 30,000 and 40,000 feet for a reason: thinner air means less drag, but engines and passengers still need enough air to work.

Cold weather drains drone batteries faster and can cut flight time sharply. Warm storage, gentle warm-ups, and lower expectations keep winter flights safe.

Turbulence feels alarming, but modern aircraft are built for far worse than a bumpy ride. The real risk is to unbelted passengers, not the plane.

Sunset is the hardest light for a drone camera: bright sky, dark ground, and fast-changing colour. These settings keep your 4K footage smooth and usable.

Early jets had square windows, and that shape turned out to be dangerous. Round windows spread pressure loads evenly and keep the fuselage strong.

A rocket launch is over in minutes, and a bad viewing spot can ruin it. Pick your site, timing, and backup plan before launch day.

Forgetting airplane mode will not bring a plane down, but there are real reasons crews still ask for it, from network interference to battery drain.
