RiverBoat...has Bournemouth upset you at some point? Only Brize "say rocas" and yet Bournemouth "bark remain ocas"???
Its cautionary as many have mentioned to say to an a/c remain outside controlled airspace until we're able to get back to that a/c with a clearance to cross through, subject many things..traffic, weather, emergencies etc. If it said in the transmission along with pass your message then yes, waste of time!
