Jet streams can be helpful and detrimental to pilots, so the airline industry uses these water vapor images to adjust flight routes.
Jet streams occur at very high altitudes — 30,000 to 40,000 feet — which is why they were not definitively identified until World War II, when pilots noticed intense headwinds during long - distance military missions.
