Were you on a buddy box, or were you just handing the transmitter back and forth?

As an instructor (Who only teaches on a buddy box) I cant imagine watching an airplane go into the ground waiting on the student to ask me to take over. Its a reflex that is subconscious, if I see a plane in trouble I will wait as long as I can but when I know its getting close I instinctively let go of the button and catch the plane, I dont ask for permission. Im in control and I decide whos got the plane.
