Vapour Trails created by planes:
Areas of low pressure form around the edge of the wing, creating vortices - tubes of circulating air - that leave trails behind the wing’s tips. The low pressure in these areas mean that cold air can condense, leaving spectacular trails of water or even ice behind the plane.When a plane passes through a cloud, water vapour and ice from the clouds are sucked into the vortices, adding to the effect.
The air pressure created around the plane can also cut through a cloud, parting the vapours and leaving spectacular patterns behind as the clouds gather around the vortices. A plane breaking the sound barrier produces a similar condensation effect around an aircraft, caused by an area of low pressure rapidly forming towards the plane’s tail.

happy aviation day!
Don’t need candles on my birthday today, the two burners on this USN F/A-18E will do just fine!
