The video introduces a British invention that could transform aviation by allowing jet airliners to take off and land almost vertically using a rotating aerofoil. This innovation, demonstrated with models, promises to double the lift compared to traditional helicopters, potentially enabling rapid travel between city centers, such as London and Paris, in just 50 minutes.

What event is highlighted at the beginning of the video?

• A new movie release

• A radio-controlled model plane championship

• A car racing event

• A music concert

What is the main feature of the British invention discussed in the video?

• It allows planes to fly faster than sound

• It enables planes to take off almost vertically

• It reduces fuel consumption by half

• It increases passenger capacity

How does the aerofoil design function during flight?

• It rotates continuously

• It stops in line with the fuselage

• It folds into the wings

• It detaches from the plane

What is the advantage of the telegraph pole rotor's aerofoil shape?

• It allows for longer flights

• It increases fuel efficiency

• It reduces noise pollution

• It provides twice as much lift as a helicopter

How long would it take for a 70-seater heli-jet to travel from London to Paris using this invention?

• 1 hour

• 1 hour and 30 minutes

• 50 minutes

• 30 minutes
