Looking: SSW

Not sure what's happening here; I think the 'main' cloud (running away from photographer in image) is an old condensation trail that's considerably spread apart - then there's been some 'interference' by a/c in transit possibly disturbing the thermal/humidity structure through the layer and triggering instability. I've noted it as Cc cas & flo (I could detect distinct ice trails/tails below the cloud elements). Not seen anything quite like it before.

Interesting. Part of it looks like a "distrail" (clear space cut through cloud) possibly caused by the heat of the aircraft's engines evaporating the cloud. But in you case it looks like that the heat has also caused instability and convective type clouds to form.
