because I was right behind him holding.

Dudley, It's a good story, but I'm afraid I find it
a bit hard to believe.

1. In my experience, admittedly years ago, we were instructed not to
roger for further transmissions and to break off the approach if we
failed to hear the controller for about three seconds. Actually, it
sounded like the controller never took his (her) finger off the mike
button, which would block any calls from the pilot.

2. If you were holding, you would be on a different frequency. The
final controller has a channel all his (her) own, for obvious reasons.

Precisely correct Vince, my experiences were quite a few years
ago too but my long term memory is crystal clear, all our GCA's
were done on 134.1, and that's all that was done on there, GCA's.

Mind you, I have no idea what I had for breakfast this morning...
(or whether for that matter)
