On approach to CGN one night some years ago when it was very busy with night freight. We are using 14L, cloud base around 500 feet and sudenly the Tower Freq goes off the air (but we don't know that - why would we?).
Pop out of cloud, go visual and, lo and behold, there are the lights of an aircraft on the threshold waiting for take-off.
Go Around and contact Approach. Told that Tower had suffered an RT failure.
On subsequent contact with Tower, I am told that they had been flashing a red light at me from the Tower!
Red light from the Tower at 500 feet?
Get real!
For a start, where the hell is the Tower at CGN?
You will be astonished to learn that looking for a Red Light from the Tower was pretty low down in my list of priorities.
Incidentally, I actually saw Chesty Morgan in the Flyers Club in Gander in the 1970s. I can confirm that she was all "teeth and t+ts".
