Hypotheses
Cocurrent stream (cocurrent track)
Limited the scope of the perturbed gaseous environment arising from the movement in her body. For example, the area of disturbed air in the form of vortices, breaking away from the wingtips of an airplane. Each vortex is formed due to the tendency of air to flow from region of high pressure (under the wing) to an area of low pressure (above the wing). Although the vortices fade out very quickly (about 5 minutes), but still behind a heavy aircraft, they can stretch for miles.
Investigation
On the basis of appearance is a concurrent trace of the plane, which is clearly visible in the cloud.
