　Flying to another country can sometimes take several days. But the designer of a futuristic jet (喷气式飞机) says his plane could take you around the world in your lunch break.

　According to an article in The Sun, the plane called the Antipode, could carry 10 people and use rocket boosters (火箭助推器) to go12 km high. Then it could fly from London to New York in less than 20 minutes, or from New York to Shanghai in 24 minutes.

　A normal Boeing 747 has a top speed of 917 km/h. The fastest plane in the world right now is Air Force One. It carries the president of the United States and can reach 1,092 km/h. But the Antipode would be capable of reaching a crazy 25,750 km/h!

　Canadian designer Charles Bombardier says his plane could be 10 times faster than the Concorde, which could fly at 2,180 km/h. The Concorde used to be the world's fastest passenger plane between 1976 and 2003. But the Concorde was very noisy and its nose got dangerously hot when it flew, A Concorde crashed in 2000, killing 114 people. No Concordes were flown again after 2003.

　The Antipodes design includes a special nose that stops it from overheating and having the same problems that the Concorde did. New technology, recently tested by NASA, makes the Antipode the perfect shape and weight to fly fast and safely.

　"It's always something that people would like - a transportation system that could take you from one place on the planet to the other side," Mr Bombardier told the BBC.

　Don't try to buy a ticket on the plane yet, though. The design is just a concept and will need more research before it becomes a reality.
