Air transport began over 200 years ago. Here's a timeline of some of the major developments.
The Montgolfier brothers launched their first hot air balloon.

The first airship, fitted with a steam engine was flown by Henri Giffard from Paris. The airship could only fly forward.
The Wright Brothers made the first engine powered flight in 'The Flyer'. It flew for 12 seconds and travelled 37 metres.
The first all metal plane was built by a German, Herman Junkers. It travelled at 170 km per hour.
The first sea plane, having one or two floats in place of the usual under carriage, this plane took off from, and landed on, water.
Flying boats were used to cross oceans because aircraft could not carry enough fuel to travel long distances non-stop. Flying boats could fly between seaports and islands, refuelling as they went. They didn't need runways, and it was thought to be safer to fly across water in an aircraft that could float. Flying boats have floats where the undercarriage would be on a land-based aircraft.
In the 1930s the use of twin (two) engines enabled planes to carry more passengers.
The first practical helicopter which could carry passengers, was developed.
How does a helicopter fly?
On a helicopter the wings are called rotor blades. The rotor blades have an aerofoil shape, curved on the top and flat on the bottom, just like the wings of an aeroplane. When the rotor blades rotate, the pressure of the air flowing under the blades is greater than the fast-moving air above them. The strong pressure below pushes the helicopter into the air, giving it the lift it needs to fly. To move up, down, forward or backward or to hover motionless in the air, the pilot changes the angle or tilt of the helicopter's rotor blades. The tail rotor blade stops the helicopter from spinning around in a circle.
This flying boat, 'Spruce Goose' was built of wood. It only flew once, over a distance of about 2 kilometres. It is the largest plane ever built.
Early jet liners carried about 40 passengers, and had jet engines with propellers called turbo-prop engines.
Jet passenger planes had turbo-jets and no longer needed propellers.
How does the jet engine work?
Air is sucked into the front of a jet engine and is compressed (squashed) by powerful fans, called turbofans. The compressed air is mixed with fuel and ignited. As the fuel burns, hot gases rush out of the back of the engine, pushing the aircraft along. As the gas leaves the engine, it spins turbines which make the turbofans at the front of the engine work.

Commercial jet liners were able to carry over 400 passengers After a disasterous crash in 2000, and other matters, Concorde was taken out of service in 2003.
The Russian built Tupolev Tu-144 was the first supersonic passenger aircraft. It flew on December 31, 1968; two months ahead of the first flight for the Concorde SST. Concorde flew at speeds of up to 2100 kilometres per hour carrying 100 passengers.
The first re-usable space vehicle, the space shuttle 'Colombia' was launched.
The largest passenger aircraft, (so far!) the double-decked, Airbus A380 can carry more than 800 passengers.
The 787 Dreamliner a long-range, mid-size wide-body, twin-engine jet airliner came into service. It is can carry up to 250 passengers. It is a lighter and more energy efficient aeroplane.
