Same way, same day formation :p. What we used to call 'in company' to get around inside controlled airspace with one clearance.

What a bizarre thread, which appears to be a poor attempt to bring the organiser of the photo shoot into some sort of justification tribunal.

What is an auth sheet?
Police and AA don't use them

No auth sheet but any flight that isn't a direct Police task has to be approved by Puzzle Palace in W Yorks.

Sigh - that escalated quickly.

Still, nice photos, eh?
