Interesting phenomena, anyone got details on how this actually forms?
As the cloud forms it then seems to follow the aircraft, it can't be as straight forward as first thought. Is it a factor of the particulate from the exhaust? or does the air temp have to be extremely low to produce. Is there any adverse affect on the airframe?
I have have worked in a variety of regions in temps of -30 to +40 degC and not come across this before.
Thanks
