BEIJING: For the first time, China's air force on Sunday successfully test flew warplanes from a highway strip in central China's Henan Province.Flight tests of military aircraft including the third generation of warplanes were held on the Zhengzhou-Minquan highway, state-run Xinhua news agency reported.
Common practice in Sweden where it takes a day or more to prepare the road as an air strip. Any central divider is removed to allow use of the full width of the road and the surface is swept of debris. Roads so used are thicker with a concrete base.
I image that sand storms would be a problem in Henan Province.
