I always used to titter when one of the 'old boys' at Boscombe ( in the good old days when we controllers were CAA ) used to round off his talkdown with 'Look ahead and land'.
Once, with a film camera pointing at me, I had to 'do' a PAR talkdown with a pretend aircraft. It was amazingly difficult, one minute chuntering away as if I was talking to a Jag on one engine, the next slowly as if to a Scout
