What happens to the water which forms on a plane's wings?

When a plane is moving through the air, I assume that friction heats the wings somewhat and that this would cause the water vapor in the atmosphere to condense. What happens to this water? Is the amount just so small that the condensation isn't visible from the ground?What happens to the water which forms on a plane's wings?Water vapor would condense on cold objects, not hot ones. Like when you get a cold drink out of the fridge, and water condenses on the bottle.



If the plane flies from cold air to moist warmer air, then the cold wings will condense water, but it gets blown off pretty quickly. The problem is if it is cold enough for the water to freeze. Then ice can form on the plane's wings, and that can be a problem for control of the plane.What happens to the water which forms on a plane's wings?Even though the air temperature at 35000 ft. alt is -65 degrees f. the Surface of the wings on an aircraft are about 140 degrees f. This temperature is caused by friction.
