Ah, the vagueness of your reply proves you are a weatherman!!
My maths master was an RAF met-man during WW2. He once explained to us why vectoring was important by recounting the story of when he was at an aerodrome near Bristol and an He-111 landed. The crew bundled out and were surprised to be looking down the barrels of various bits of weaponry. They thought they were in Brittany.
"The nav got his wind reading wrong!"
Looking forward to your tales.
