Strange happenings up North
 

Jump into the plane tonight to move it into the hangar and as usual the GPS fired up with a strange line on the map page running from down south up over Edinburgh thru Fife and Angus up to Wick,

Now that line was not there yesterday and I haven't updated the GPS, upon highlighting the line with the pointer it came up with " Met research flights area Charlie surface to 35000"

How the fiddlesticks did this get on my GPS ?
