Small white cloud displays unusual movements west of Mt Rainier in Washington State

I was looking south from a friend's condominium deck in the Seattle community of Ballard. We could clearly see Mt. Rainier, approximately 75 miles to the south. A small, white cloud appeared close to the west flank of the mountain, approximately 2/3 of the way to the summit. Over a period of two minutes, the white cloud began to behave in an odd manner as it drifted, and then moved very rapidly to the west, straight away from Rainier, maintaining a constant elevation. As we were watching, the cloud abruptly stopped, and then dissolved before our eyes.

Airplanes could be seen it the same general area, before, during and after the cloud was seen moving. They were also to the west of Rainier, and presumably taking off to the north from Sea-Tac airport. These airplanes were clearly darker than the object, and their direction and motion was entirely different.
