By 2050, you may be able to travel from London to Sydney in just 90-minutes, on the hypersonic SpaceLiner.

Traveling between Europe and the US would be reduced to just over 60 minutes. The SpaceLiner would take approximately eight minutes to reach the earth’s upper atmosphere before gliding back to Earth at hypersonic speeds of more than 15,000mph. Engineers hope to use a liquid oxygen and hydrogen rocket fuel, leaving water vapor as waste.
