Norman and others,
The cloud formation is entirely man made, and consists of 'bundles'
ofcontrails in a fairly strong anticyclonic shear. Playing an IR animation
shows individual trails forming as the older ones rotate anticyclonically.
The first trails appeared near 04z as the overnight pond hoppers headed for
Europe. A nice visual example of vorticity.

There's some odd-looking cirrus formation to the west of Scotland on the
following loop (the URL will probably wrap to the next line)

It looks too regular to be natural but I'm sure it is natural.
