No Flight Plan

Someone answered my querie awhile back as to why Medevac Helo’s do not have to file a flight plan…what about News Helo’s ? When you search the Tail ID of Global Calgary’s…it shows I believe the initial Test Flight when they got it…thats it ! Sorry, I can’t remember the ID of it now. They get to buzz around the city without having to file any type of plan or ? Oh, found it in an earlier post… C-FLWB is Global 1

News helos generally fly VFR.
