Thats a good Q. Especially given that they are oftimes giving 'Fog warning current' but you can see bleeding Cardiff from the 09 threshold!
They,ve stopped doing it now but it used to be the practice at BRS, when the wx was ****ty, (which it often is!), to make you state your 'souls on board' as you taxiied. As if they expected you were going to have a whoopsy. Needless to say the fire crews were 'stood to' during these high risk ops
I tell you, BRS is a funny place
