Aircraft on freq with stuck mike, of course you can talk over them, I hear:
Indian accent pilot - "Aircraft with stuck mike this is captain of AI101 your mike is stuck we cant talk"
American accent pilot - "Ya know he cant hear you as he has a stuck mike"
Indian accent pilot - "Kolkata this is AI101, there is an aircraft with a stuck mike please have them reported immediately as we cannot give RT to you"
Kolkata - AI101 Rog we are aware of this
....... and these guys are captains!
