I think it's called the A2, and apparently, it'll be able to fly halfway around the world in five hours. It is twice as fast as the Concord.
Instead of a 22 hour flight between Brittain and Sydney, it'll be 4 1/2.
There's the video which explains it all. So my question to you is:
Do you think these types of airplanes will take over the whole flying industry, and replace all the other airplanes? Is this the way we'll be travelling in twenty years or so?
