THIS perfectly-timed photo shows the moment a US Air Force jet created its own cloud - thanks to a rare combination of speed, temperature, humidity and pressure.

Amateur photographer Wayne Lewis, 38, caught the jet on camera as it flew through Talyllyn on the world-famous Mach Loop.

He managed to capture the split-second moment the jet created - and then emerged - from the white fluffy cloud.

This rare phenomenon only occurs in a fraction of a second when there is the perfect combination of air speed, temperature, humidity and air pressure.

Often mistaken as the effect of a ‘sonic boom’, it happens when water vapour in the humid air is instantaneously condensed into droplets.

Teacher Wayne from Welshpool, said: “I shot the photos from the top of a hill above a valley, hoping that the aircraft would pass.

“From there I managed to be almost at eye-level with the pilots. I was incredibly lucky to get this photo.

“The photos have been extremely popular with the people I have shown. It’s extremely rare to get a photo like this.”

These type of clouds are often mistaken as the effect of a ‘sonic boom’ - when the aircraft breaks the sound barrier at 767mph.
