Chinese researchers have planned to build an airport in Antarctica in November. The Chinese (be) not very used to flying to the southernmost continent, because the country s first polar plane, the Snow Eagle 601, (put) into use only three years ago.
Before the Snow Eagle 601, Chinese researchers traveled to the ice-covered land by ship, which took significantly (long) than flying. There are currently more than 20 airports in Antarctica, but none of them belong to China. The Snow Eagle 601 has to rely on Russian airports (take) off and land. That's the Chinese researchers decided to build their own. Building an airport in Antarctica is very different from building one elsewhere. The continent is covered by a (constant) moving layer of ice, so the builders must find somewhere that moves at the slowest possible pace and in a (fix) direction.
The builders managed to find a spot back in early 2017 following tough measuring process that took place in the storm-like polar winds. The next problem is the snow. The soft nature of snow makes a bad material for a runway. So the builders must use road roller-like (machine) to press the snow, which can be very time-consuming in extreme coldness.
