A question with regard to the radio calls, frequently stepping on each other. Given that the 737 was quite far away at low altitude, could poor reception help explain the overlaps in transmission ? Perhaps each party thinking the other had finished - and clearly the controller very keen to be able to help, despite being busy with other tasks at the same time?
The emotion in the Air Traffic Controller's voice at the end is clear to hear. Superb that both crew survived a nail biting experience..
