British engineers and scientists have published plans for a new hypersonic plane called
the A2. It will be very fast. At the moment, a flight from London in the UK to Sydney in
Australia takes about twenty-one hours but with the A2 the same flight will take about four-
hours. The flight will fly at 4,500 kilometers per hour and will fly at an altitude of over
10,000 meters. it will carry 300 passengers but it won't have any windows because scientists
haven't found glass that is strong enough. It will be better for the environment than other
plancs because the engines won't produce gases that cause pollution.
In the future, will people travel from London to Australia for the
weekend? It's possible! But how much will a ticket cost? The planners say that it won't
be very expensive - about £2,000. The A2 will be ready for its first flight in 2030.
