Skywriting in the UK?

[Self Loading Freight]

A friend asks why there don't seem to be any skywriting companies in the UK. I seem to remember that the CAA doesn't normally issue permits for that, but I can't find chapter and verse.

Is this so?

Thanks,

Maybe they just can't sell the services:hmm:

Or even "spell" the service.....
