So far as using an ALDIS ..I had a BA 757 land without clearance...he had set 118.1 instead of 118.3. We never heard from him when transferred from APP. I shone the ALDIS at him...transmitted blind...and he landed safely. It was a buggah of a job to convince him that he HAD a clearance to land.

The pilot did not call me & I was intrigued to see when he would. There was no traffic to affect the a/c, so I didn't say anything & let it run.
