Speedywheels, yip Coquet Island was indeed a favourite entry point but was universally known as Amble Light in the RAF. I suspect many crews would have no idea about Coquet, unless they have spent time at Boulmer and in the pubs in Warkworth.
It might have been an entry point to one of the link routes back in the V force days, when low flying was restricted to specific routes, but you will need to ask someone 15 years older than me to confirm that
