A short compilation of aircraft flying through clouds and moist air, showing the spiraling vortices that wings leave behind. The footage shows wingtip vortices and the way planes disturb cloud layers.

Numberphile with Tom Crawford of Oxford explains the Reynolds number, the second of three videos on Navier-Stokes and fluid flow, with demonstrations of laminar versus turbulent behavior.
