Allegedly it was this that led to the AP detailing the specified callsigns that were to be used per squadron.
The Red Arrows had a double ejection a good few years ago (iirc, actually quadruple, two bangs per aircraft) when someone called that one Gnat was on fire but got the formation numbering wrong.
