One wing vapour trails?

[tixntox]

We watched four military jets in formation yesterday and the vapour trails were from the tips of the right wings only. Seemed strange as they are usually in two streams or one central stream. Any suggestions? Fuel dumping maybe?

Were they banking at the time? That might cause the pressure coming off one wingtip to be low enough to create water vapour but not be low enough at the other tip.

Or, if they were in a close formation, then each aeroplane’s inside wing may be disrupting the airflow over the next areoplane’s outer wing....etc....if you see what I mean.

The pressure at the wingtip needs to drop far enough away from the ambient pressure for the water vapour to form, that does not always happen on both wingtips at the same time. It also only happens when a certain amount of lift is being created. The amount of lift changes as the aircraft rolls and yaws. That’s why you sometimes only see a wingtip vortex coming off one wing when an aeroplane is flying on its own.

Were the planes red by any chance?

Were they heading west? Low pressure is to the north of the UK at the moment

The wind speed and direction also plays a part. If they were flying in a crosswind, which could be at 200mph+ up at 10,000 ft it plays a big part in causing a differing wingtip exit pressure - as above.
