"The Mast"
As a long time Teesside Airport enthusiast I can recall that aircraft approaching from the east and southeast where frequenty given vectors to avoid "The Mast", or to report "clear of The Mast", "Visual with The Mast" etc. The Mast being the Bilsdale Transmitting Station Mast on Bilsdale West Moor I was wondering why I have never heard this particular "Hazard to Navigation" mentioned in recent years. Any ideas ?.
