Pilots often take advantage of the ____,which are highly-speed winds between 7km and 16 km above earths surface.

Answer 1

I believe it is called or referred to as the "Jet Stream". During World War II, allied pilots encountered high speed winds in the upper air. They named those winds after the fastest planes they came up against: fighters equipped with jet engines! Jet stream winds in winter time can reach up to 300 MPH as well!
