I've seen for some time.

Are you sure it wasn't iridisation in some high cirrus?

It is the right time of year for them so it may have been a display.

I didn't see it. Did anyone get photographs of them? That would be
helpful.
Can anyone confirm if they were in fact lenticular stratospheric
nacreous clouds?
They do have a very aerodynamic wind swept characteristic shape.

Some pictures from the big display of 1996 on my webpage (together
with a list of all known UK displays for the past century)

They form usually at such a high altitude as to be visible over a very
wide area.

Thanks for the reply guys and I can assure you it was a single small cloud.
(I was driving south, so guess there could have been some behind me). You
had me doubting myself and I had to check out cloud sites to confirm it to
myself, but anyone who witnessed/photographed 1996 won't forget them.
Martin your description "bright white" sums it up quite well, it was very
bright. Can't think why I didn't stop and photograph it.
