Zheping Huang wrote about a flying train:

• Impressed by the idea of Elon Musk’s Hyperloop, China is planning its own “flying train”.
• The plan is to build a train that can run at 4,000 kilometers per hour – three times the speed of sound.
• If China achieves this the train will be ten times faster than the fastest bullet train in the world – and four times faster than a commercial jet.
• It will also be faster than Musk’s Hyperloop – which is only projected to reach speeds of 1,200 kilometers per hour.
• Critics note that any such transport system would likely be prohibitively expensive compared to an airline ticket.
